A signature aggregation scheme, can take a list of tuples

(message, signature, public key), and produce one signature
|
|
||||||
that can be verified with the list of messages and public keys.

An additional important property we need here: we cannot get

|

the original signatures from an aggregated one.

### Biscuit signature scheme
|
### Biscuit signature scheme
|
||||||
|
|
||||||
Assuming we have the following primitives:
|
Biscuit tokens are based on public key cryptography, with a chain of Ed25519
|
||||||
|
signatures. Each block contains the serialized Datalog, the next public key,
|
||||||
|
and the signature by the previous key. The token also contains the private key
|
||||||
|
corresponding to the last public key, to sign a new block and attenuate the
|
||||||
|
token, or a signature of the last block by the last private key, to seal the
|
||||||
|
token.
|
||||||
|
|
||||||
- `Keygen()` can give use a publick key `pk` and a private key `sk`
|
#### Signature (one block)
|
||||||
- `Sign(sk, message)` can give us a signature `S`, with `message` a byte array or arbitrary length
|
|
||||||
- `Aggregate(S1, S2)` can give us an aggregated signature `S`. Additionally, `Aggregate`
|
|
||||||
can be called with an aggregated signature `S` and a single signature `S'`, and return a new
|
|
||||||
aggregated signature `S"`
|
|
||||||
- `Verify([message], [pk], S)` will return true if the signature `S`
|
|
||||||
is valid for the list of messages `[message]` and the list of public keys `[pk]`
|
|
||||||
|
|
||||||
#### First layer of the authorization token
|
* `(pk_0, sk_0)` the root public and private Ed25519 keys
|
||||||
|
* `data_0` the serialized Datalog
|
||||||
|
* `(pk_1, sk_1)` the next key pair, generated at random
|
||||||
|
* `sig_0 = sign(sk_0, data_0 + pk_1)`
|
||||||
|
|
||||||
The issuing server performs the following steps:
|
The token will contain:
|
||||||
|
|
||||||
- `(pk1, sk1) <- Keygen()` (done once)
|
|
||||||
- create the first block (we can omit `pk1` from that block, since we assume the
|
|
||||||
token will be verified on a system that knows that public key)
|
|
||||||
- Serialize that first block to `m1`
|
|
||||||
- `S <- Sign(sk1, m1)`
|
|
||||||
- `token1 <- m1||S`
|
|
||||||
|
|
||||||
#### Adding a block to the token
|
|
||||||
|
|
||||||
The holder of a token can attenuate it by adding a new block and
|
|
||||||
signing it, with the following steps:
|
|
||||||
|
|
||||||
- With `token1` containing `[messages]||S`, and a way to get
|
|
||||||
the list of public keys `[pk]` for each block from the blocks, or
|
|
||||||
from the environment
|
|
||||||
- `(pk2, sk2) <- Keygen()`
|
|
||||||
- With `message2` the block we want to add (containing `pk2`, so it
|
|
||||||
can be found in further verifications)`
|
|
||||||
- `S2 <- Sign(sk2, message2)`
|
|
||||||
- `S' <- Aggregate(S, S2)`
|
|
||||||
- `token2 <- [messages]||message2||S'`
|
|
||||||
|
|
||||||
Note: the block can contain `sealed: true` in its keys and values, to
|
|
||||||
indicate a token should not be attenuated further.
|
|
||||||
|
|
||||||
Question: should the previous signature be verified before adding the
|
|
||||||
new block?
|
|
||||||
|
|
||||||
#### Verifying the token
|
|
||||||
|
|
||||||
- With `token` containing `[messages]||S`
|
|
||||||
- extract `[pk]` from `[messages]` and the environment: the first public
|
|
||||||
key should already be known, and for performance reasons, some public keys
|
|
||||||
could also be present in the list of common keys and values
|
|
||||||
- `b <- Verify([messages], [pk], S)`
|
|
||||||
- if `b` is true, the signature is valid
|
|
||||||
- proceed to validating rights
|
|
||||||
|
|
||||||
### Sealed Biscuit scheme
|
|
||||||
|
|
||||||
In some cases, we might want to convert the token to a symmetric key based
|
|
||||||
token that cannot be attenuated further. Common use case: contact the verifier
|
|
||||||
once, the verifier checks the signature, and generates from it a short lived
|
|
||||||
token with the same authorization, but that can be checked much faster than
|
|
||||||
public key based tokens.

## Annex 1: Cryptographic design proposals
|
|
||||||
|
|
||||||
### Pairing based cryptography
|
|
||||||
|
|
||||||
proposed by @geal
|
|
||||||
|
|
||||||
Assuming we have a pairing e: G1 x G2 -> Gt with G1 and G2 two additive cyclic groups of prime order q, Gt a multiplicative cyclic group of order q
|
|
||||||
with a, b from Fq* finite field of order q
|
|
||||||
with P from G1, Q from G2
|
|
||||||
|
|
||||||
We have the following properties:
|
|
||||||
- `e(aP, bQ) == e(P, Q)^(ab)`
|
|
||||||
- `e != 1`
|
|
||||||
|
|
||||||
More specifically:
|
|
||||||
|
|
||||||
- `e(aP, Q) == e(P, aQ) == e(P,Q)^a`
|
|
||||||
- `e(P1 + P2, Q) == e(P1, Q) * e(P2, Q)`
|
|
||||||
|
|
||||||
#### Signature
|
|
||||||
|
|
||||||
- choose k from Fq* as private key, g2 a generator of G2
|
|
||||||
- public key P = k*g2
|
|
||||||
|
|
||||||
- Signature S = k*H1(message) with H1 function to hash message to G1
|
|
||||||
- Verifying: knowing message, P and S
|
|
||||||
```
|
|
||||||
e(S, g2) == e( k*H1(message), g2)
|
|
||||||
== e( H1(message), k*g2)
|
|
||||||
== e( H1(message), P)
|
|
||||||
```
|
|
||||||
|
|
||||||
#### Signature aggregation
|
|
||||||
|
|
||||||
- knowing messages m1 and m2, public keys P1 and P2
|
|
||||||
- signatures S1 = Sign(k1, m1), S2 = Sign(k2, m2)
|
|
||||||
- the aggregated signature S = S1 + S2
|
|
||||||
|
|
||||||
Verifying:
|
|
||||||
```
|
|
||||||
e(S, g2) == e(S1+S2, g2)
|
|
||||||
== e(S1, g2)*e(S2, g2)
|
|
||||||
== e(k1*H1(m1), g2) * e(k2*HA(m2), g2)
|
|
||||||
== e(H1(m1), k1*g2) * e(H1(m2), k2*g2)
|
|
||||||
== e(H1(m1), P1) * e(H1(m2), P2)
|
|
||||||
```
|
|
||||||
|
|
||||||
so we calculate signature verification pairing for every caveat
|
|
||||||
then we multiply the result and check equality
|
|
||||||
|
|
||||||
we use curve BLS12-381 (Boneh Lynn Shacham) for security reasons
|
|
||||||
(cf https://github.com/zcash/zcash/issues/2502
|
|
||||||
for comparions with Barreto Naehrig curves)
|
|
||||||
assumes computational Diffe Hellman is hard
|
|
||||||
|
|
||||||
Performance is not stellar (with the pairing crate, we can
|
|
||||||
spend 30ms verifying a token with 3 blocks, with mcl 1.7ms).
|
|
||||||
|
|
||||||

||||||

#### Signature (appending)
|
||||||
|
|
||||||
Field elements in F have bit lengths divisible by 16
|
With a token containing blocks 0 to n:
|
||||||
|
|
||||||
hLen is equal to 2n
|
Block n contains:
|
||||||
|
- `data_n`
|
||||||
|
- `pk_n+1`
|
||||||
|
- `sig_n`
|
||||||
|
|
||||||
Steps:
|
The token also contains `sk_n+1`
|
||||||
|
|
||||||
Keygen:
|
We generate at random `(pk_n+2, sk_n+2)` and the signature `sig_n+1 = sign(sk_n+1, data_n+1 + pk_n+2)`
|
||||||
`(pk, sk) <- Keygen()`: sk random x with 0 < x < q

|
||||||
#### Basic EC-VRF behaviour
|
The token will contain:
|
||||||
|
|
||||||
Sign(pk, sk, message):
|
|
||||||
|

|
|
||||||
- s = k + c * sk mod q
|
|
||||||
- pi = (gamma, c, s)
|
|
||||||
|
|
||||||
Verify(pk, pi, message) for one message and its signature:
|
|
||||||
|
|
||||||
- (gamma, c, s) = pi
|
|
||||||
```
|
|
||||||
u = pk^-c * g^s
|
|
||||||
= g^(sk*-c)*g^(k + c*sk)
|
|
||||||

|
|
||||||
```
|
|
||||||
- h = ECVRF_hash_to_curve(pk, message)
|
|
||||||
```
|
|
||||||
v = gamma^-c * h^s
|
|
||||||
= h^(sk*-c)*h^(k + c*sk)
|
|
||||||

|
|
||||||
```
|
|

|
|

First block: Sign0(pk, sk, message)

- `gamma_(n+1) = h_(n+1)^sk_(n+1)`

- `k = ECVRF_nonce(sk, h)`

u_n = pk_0^-c_0 * .. * pk_n^-c_n * g^S_n

Verify([pk], PI, [message]) (with n blocks):
|
#### Verifying
|
||||||
|
|
||||||
|
For each block i from 0 to n:
|
||||||
|
|
||||||
Aggregate(pk', pi', [pk], PI) with [pk] list of public keys and PI aggregated signature:
|
- verify(pk_i, sig_i, data_i+pk_i+1)
|
||||||
- `([gamma], [c], S, W, C) = PI`
|
|
||||||
- check that `n = |[pk]| == |[message]| == |[gamma]| == |[c]|`
|
If all signatures are verified, extract pk_n+1 from the last block and
|
||||||
```
|
sk_n+1 from the proof field, and check that they are from the same
|
||||||
U = pk_0^-c_0 * .. * pk_n^-c_n * g^S
|
key pair.
|
||||||
= g^(sk_0*-c_0) * .. * g^(sk_n*-c_n) * g^(k_0 + sk0*c_0 + .. + k_n + sk_n*c_n)
|
|
||||||
= g^(k_0 + .. + k_n)
|
#### Signature (appending)
|
||||||
```
|
|
||||||
|
With a token containing blocks 0 to n:
|
||||||
|
|
||||||
|
Block n contains:
|
||||||
|
- `data_n`
|
||||||
|
- `pk_n+1`
|

|
- `sig_n`
|
||||||
|
|

|
The token also contains `sk_n+1`
|
||||||
|
|
||||||
|
We generate the signature `sig_n+1 = sign(sk_n+1, data_n + pk_n+1 + sig_n)` (we sign
|
||||||
|
the last block with the last private key).
|
||||||
|

The token will contain:

### Elliptic curve verifiable random functions: second method
|
|
||||||
|
|
||||||
This is a variant of the previous scheme, for which the product of
|
|
||||||
gamma points is precalculated, so that we do not need to do it to
|
|
||||||
aggregate a new signature or verify it. This also reduces the size
|
|
||||||
of the signature.
|
|
||||||
|
|
||||||
Same primitives as before:
|
|
||||||
|
|
||||||
```
|
|
||||||
F - finite field
|
|
||||||
2n - length, in octets, of a field element in F
|
|
||||||
E - elliptic curve (EC) defined over F
|
|
||||||
m - length, in octets, of an EC point encoded as an octet string
|
|
||||||
G - subgroup of E of large prime order
|
|
||||||
q - prime order of group G
|
|
||||||
cofactor - number of points on E divided by q
|
|
||||||
g - generator of group G
|
|
||||||
Hash - cryptographic hash function
|
|
||||||
hLen - output length in octets of Hash

|
||||||
```
|
```

|
||||||
Constraints on options:
|
#### Verifying (sealed)
|
||||||
|
|
||||||
Field elements in F have bit lengths divisible by 16
|
For each block i from 0 to n:
|
||||||
|
|

sig from the proof field, and check `verify(pk_n+1, sig_n+1, data_n+pk_n+1+sig_n)`

### Challenge tokens
|
|
||||||
|
|
||||||
Another method based on a more classical PKI, where the token contains
|
|
||||||
the secret key of the last caveat. To send the token for verification,
|
|
||||||
that key is used to sign the token with a nonce and current time, to
|
|
||||||
prove that we own it. We send the token without the key, but with the
|
|
||||||
signature. The verification token cannot be further attenuated.
|
|
||||||
|
|
||||||
Here's a description of the scheme:
|
|
||||||
|
|
||||||
```
|
|
||||||
(pk1, sk1) = keygen()
|
|
||||||
(pk2, sk2) = keygen()
|
|
||||||
s1 = sign(sk1, caveat1+pk2)
|
|
||||||
token1=caveat1+pk2+s1+sk2
|
|
||||||
```
|
|
||||||
|
|
||||||
Minting a new token
|
|
||||||
```
|
|
||||||
(pk3, sk3) = keygen()
|
|
||||||
s2 = sign(sk2, caveat2+pk3)
|
|
||||||
token2=caveat1+pk2+s1+caveat2+pk3+s2+sk3
|
|
||||||
```
|
|
||||||
|
|
||||||
Sending token2 for verification:
|
|
||||||
```
|
|
||||||
verif_token2=caveat1+pk2+s1+caveat2+pk3+s2
|
|
||||||
h = sign(sk3, nonce+time+verif_token2)
|
|
||||||
sending verif_token2+h
|
|
||||||
```
|
|
||||||
|
|
||||||
The verifier knows pk1 and can check the chain, and h allows checking that we hold sk3
|

### Cryptography
|
### Cryptography
|
||||||
|
|
||||||
#### Attenuable tokens
|
Biscuit tokens are based on public key cryptography, with a chain of Ed25519
|
||||||
|
signatures. Each block contains the serialized Datalog, the next public key,
|
||||||
|
and the signature by the previous key. The token also contains the private key
|
||||||
|
corresponding to the last public key, to sign a new block and attenuate the
|
||||||
|
token, or a signature of the last block by the last private key, to seal the
|
||||||
|
token.
|
||||||
|
|
||||||
Those tokens are based on public key cryptography, specifically aggregated
|
#### Signature (one block)
|
||||||
gamma signatures[Aggregated Gamma Signatures]. Signature aggregation allows
|
|
||||||
Biscuit to make a new token with a valid signature from an existing one,
|
|
||||||
by signing the new data and adding the new signature to the old one.
|
|
||||||
|
|
||||||
Every public key operation in Biscuit is defined over the Ristretto prime
|
* `(pk_0, sk_0)` the root public and private Ed25519 keys
|
||||||
order group[Ristretto], that is designed to prevent some implementation
|
* `data_0` the serialized Datalog
|
||||||
mistakes.
|
* `(pk_1, sk_1)` the next key pair, generated at random
|
||||||
|
* `sig_0 = sign(sk_0, data_0 + pk_1)`
|
||||||
|
|
||||||
Definitions:
|
The token will contain:
|
||||||
- `R`: Ristretto group
|
|
||||||
- `l`: order of the Ristretto group
|
|
||||||
- `Z/l`: scalar of order `l` associated to the Ristretto group
|
|
||||||
- `P`: Ristretto base point
|
|
||||||
- `H1`: point hashing function
|
|
||||||
- `H2`: message hashing function
|
|
||||||

||||||
##### Key generation

With secret key `x`, public key `X`, message `message`:

nextSecret: sk_1,

* `A = r * P`

* `d = H1(A)`
|
|
||||||
* `e = H2(X, message)`
|
|
||||||
* `z = rd - ex mod l`
|
|
||||||
|
|
||||||
The signature is `([A], z)`. The `[A]` array corresponds to the `parameters`
|
|
||||||
field in the protobuf schema.

#### Signature (appending)

With `([A0, ..., An], s)` the current signature:

Same process as the signature for a single block,
|
With a token containing blocks 0 to n:
|
||||||
with secret key `x`, public key `X`, message `message`:
|
|

|
- `sig_n`
|

* `z = rd - ex mod l`
|
|

|
||||||
The new signature is `([A0, ..., An, A], s + z)`
|
The token also contains `sk_n+1`
|
||||||
|
|
||||||
|
We generate at random `(pk_n+2, sk_n+2)` and the signature `sig_n+1 = sign(sk_n+1, data_n+1 + pk_n+2)`
|

#### Verifying

With:
|
For each block i from 0 to n:
|
||||||
|
|
||||||
* `([A0, ..., An], s)` the current signature
|
- verify(pk_i, sig_i, data_i+pk_i+1)
|
||||||
* `[P0, ..., Pn]` the list of public keys
|
|
||||||
* `[m0, ..., mn]` the list of messages
|
|
||||||
|
|
||||||
We verify as follows:
|
If all signatures are verified, extract pk_n+1 from the last block and
|
||||||
* check that `|[A0, ..., An]| == |[P0, ..., Pn]| == |[m0, ..., mn]|`
|
sk_n+1 from the proof field, and check that they are from the same
|
||||||
* check that `P0` is the root public key we are expecting
|
key pair.
|
||||||
* check that `[A0, ..., An]` are distinct
|
|
||||||
* check that `[(P0, m0), ..., (Pn, mn)]` are distinct
|
|
||||||
* `X = H2(P0, m0) * P0 + ... + H2(Pn, mn) * Pn - ( H1(A0) * A0 + ... + H1(An) * An )`
|
|
||||||
* if `s * P + X` is the point at infinite, the signature is verified
|
|
||||||
|
|
||||||
##### Point hashing
|
#### Signature (appending)
|
||||||
|
|
||||||
`H1(X) = Scalar::from_hash(sha512(X.compress().to_bytes()))`
|
With a token containing blocks 0 to n:
|
||||||
|
|
||||||
##### Message hashing
|
Block n contains:
|
||||||
|
- `data_n`
|
||||||
|
- `pk_n+1`
|
||||||
|
- `sig_n`
|
||||||
|
|
||||||
`H2(X, message) = Scalar::from_hash(sha512(X.compress().to_bytes()|message))` (with `|` the concatenation operator)
|
The token also contains `sk_n+1`
|
||||||
|
|
||||||
#### Sealed tokens
|
We generate the signature `sig_n+1 = sign(sk_n+1, data_n + pk_n+1 + sig_n)` (we sign
|
||||||
|
the last block with the last private key).
|
||||||
|
|
||||||
A sealed token contains the same kind of block as regular tokens,
|
The token will contain:
|
||||||
but it cannot be attenuated offline, and can only be verified by
|
|
||||||
knowing the secret used to create it.
|
|
||||||
|
|
||||||
The signature is the HMAC-SHA256 hash of the secret key and the
|
```
|
||||||
concatenation of all the blocks.

#### Verifying (sealed)
|
||||||
|
|
||||||
|
For each block i from 0 to n:
|
||||||
|
|
||||||
|
- verify(pk_i, sig_i, data_i+pk_i+1)
|
||||||
|
|
||||||
|
If all signatures are verified, extract pk_n+1 from the last block and

|
sig from the proof field, and check `verify(pk_n+1, sig_n+1, data_n+pk_n+1+sig_n)`
