Module `MinPk.Pop`Source

Proof of possession scheme described in section 3.3

A proof of possession scheme uses a separate public key validation step, called a proof of possession, to defend against rogue key attacks. This enables an optimization to aggregate signature verification for the case that all signatures are on the same message.

Sourcetype proof = Bytes.t

Sourceval sign : sk -> Bytes.t -> signature

Equivalent to core_sign with the DST given in the specification in section 4.2.3.

Sourceval verify : pk -> Bytes.t -> signature -> bool

Equivalent to core_verify with the DST given in the specification in section 4.2.3.

Sourceval pop_prove : sk -> proof

pop_proof sk implements section 3.3.2.

Sourceval pop_verify : pk -> proof -> bool

pop_verify pk signature implements section 3.3.3.

Sourceval aggregate_verify : (pk * proof) list -> Bytes.t -> signature -> bool

aggregate_verify pks msg aggregated_signature performs a aggregate signature verification. It supposes the same message msg has been signed. It implements the FastAggregateVerify algorithm specified in section 3.3.4.
