`latest.ipv8.attestation.wallet.primitives.boneh`

Implementation of the Boneh 2-DNF scheme (“Evaluating 2-DNF Formulas on Ciphertexts” by Boneh et al.).

Module Contents

`generate_prime`(→ int)	Generate p = l * n - 1 such that:
`bilinear_group`(...)	Generate a bilinear group for two generators.
`get_random_exponentiation`(...)	Create a random exponentiation of p in message space n.
`get_random_base`(→ tuple[int, int])	Create a generator for the EC.
`is_good_wp`(→ bool)	A good pairing is not 0 and has order n.
`get_good_wp`(→ tuple[int, ...)	Instead of inspecting torsion points and checking for co-primality:
`generate_primes`(→ tuple[int, int])	Generate some primes. Key size in bits.
`generate_keypair`(...)	Generate a keypair for a certain prime bit space.
`encode`(...)	Encode a message m given a public key.
`decode`(→ int \| None)	Decode a ciphertext c given a private key and the possible source messages.

latest.ipv8.attestation.wallet.primitives.boneh.generate_prime(n: int) → int

Generate p = l * n - 1 such that:

latest.ipv8.attestation.wallet.primitives.boneh.bilinear_group(n: int, p: int, g1x: int, g1y: int, g2x: int, g2y: int) → latest.ipv8.attestation.wallet.primitives.value.FP2Value: Generate a bilinear group for two generators.

latest.ipv8.attestation.wallet.primitives.boneh.get_random_exponentiation(p: latest.ipv8.attestation.wallet.primitives.value.FP2Value, n: int) → latest.ipv8.attestation.wallet.primitives.value.FP2Value: Create a random exponentiation of p in message space n.

latest.ipv8.attestation.wallet.primitives.boneh.get_random_base(n: int) → tuple[int, int]: Create a generator for the EC.

latest.ipv8.attestation.wallet.primitives.boneh.is_good_wp(n: int, wp: latest.ipv8.attestation.wallet.primitives.value.FP2Value) → bool: A good pairing is not 0 and has order n.

latest.ipv8.attestation.wallet.primitives.boneh.get_good_wp(n: int, p: int | None = None) → tuple[int, latest.ipv8.attestation.wallet.primitives.value.FP2Value]

Instead of inspecting torsion points and checking for co-primality: just brute force generate pairings until we get a good one.

latest.ipv8.attestation.wallet.primitives.boneh.generate_primes(key_size: int = 128) → tuple[int, int]: Generate some primes. Key size in bits.

latest.ipv8.attestation.wallet.primitives.boneh.generate_keypair(key_size: int = 32) → tuple[latest.ipv8.attestation.wallet.primitives.structs.BonehPublicKey, latest.ipv8.attestation.wallet.primitives.structs.BonehPrivateKey]: Generate a keypair for a certain prime bit space.

latest.ipv8.attestation.wallet.primitives.boneh.encode(pubkey: latest.ipv8.attestation.wallet.primitives.structs.BonehPublicKey, m: int) → latest.ipv8.attestation.wallet.primitives.value.FP2Value: Encode a message m given a public key.

latest.ipv8.attestation.wallet.primitives.boneh.decode(privkey: latest.ipv8.attestation.wallet.primitives.structs.BonehPrivateKey, msgspace: list[int], c: latest.ipv8.attestation.wallet.primitives.value.FP2Value) → int | None: Decode a ciphertext c given a private key and the possible source messages.
