Abstract
The invention concerns a method for generating an electronic signature key and an associated public key certificate, implemented by a client unit and a server unit, the method comprising a step during which the client unit and/or the server unit generate(s) a signature key comprising a private key and a public key, and a public key certificate comprising said public key, the method being characterized in that the client unit acquires an item of biometric data of an individual, and in that the signature key and/or the public key certificate are generated from at least a portion of said biometric data, and in that the portion of biometric metric data from which the signature key and/or the public key certificate have been generated is ephemeral and is not memorized after the signature key and the public key certificate have been generated. The invention also concerns a method for transferring a message and a system designed to implement the method for generating a signature key.
