Method for one or several assemblies producing implementing a same key cryptographic algorithm to secret, the use of the process and the electronic unit

摘要

The invention concerns a method for making secure one or several computer installations using a common cryptographic secret key algorithm (Ks), characterised in that the way to perform said computation depends, for each computer installation and for each secret key, one secret data (Ds) stored in a secret zone of the computer installation(s).
