Abstract
Method of authenticating a client to a server, the client having beforehand registered on the server by storing therein a valid identifier (ID) and a hashed word (H0; Hn) generated by applying a hash function to a disposable random variable (RAND0; RANDn; Rn) possessed/known by both the client and the server and concatenated with a sequence (ISC0; ISCn) resulting from hashing the concatenation of a password (PWD) known from the client, said disposable random variable (RAND0; RANDn; Rn) and an initialization sequence (ISCinit) possessed by the client.
