The invention relates to a cryptographic method of authentication using a decoding of an error correcting code on the basis of a public matrix, in which the public matrix is a quasi-cyclic matrix. The invention pertains also to a cryptographic device comprising computation means arranged so as to implement this method. The invention makes it possible to reduce the amount of public data to be stored in a cryptographic authentication method using a decoding of an error correcting code on the basis of a public matrix. |
