An authentication method provides a segment forming an executable
authentication plug-in previously authenticated by at least one
authentication function from an authentication library and linked to a
plurality of segments in accordance with a chaining relationship. In
response to a request for authentication of a plurality of segments
chained in accordance with the chaining relationship in this way, the
method authenticates each successive segment and, in the case of a
segment requiring the authentication plug-in, it executes the
authentication plug-in in order to authenticate the segment submitted in
this way to the authentication plug-in.
