Abstract (en)

[origin: FR2792789A1] The signature verification method has an entity prove and an entity verify. The entity prove carries out an encryption calculation separate from a private key. The process calculates an entity level prove to a value of pre validation, transmits the prove entity to the verify unit providing a value of pre-validation (1). The pre-validation value allows an entity verifier computation (3) producing a modular reduction with no requirements for division in the reduction.
