ABSTRACT:
A method for authenticating a user working in a distributed environment in the client/server mode, wherein each authentication is performed from a single piece of authentication information, known as the "passphrase", having a predetermined length and duration of use (as a function of a tally value). The method is applicable to either a one-time password (OTP) system or an OTP system integrated with a Kerberos system, or in a one-time password system used alone, and the method may be used from a trusted terminal or an untrusted terminal. A method is provided that enables reinitializing the "passphrase" at the end of the duration of use with security, even in the event of active interception, and either in an OTP system integrated with a Kerberos system, or in an OTP system used alone.
