Method For Validating A Cryptographic Parameter And Corresponding Device

摘要

An electronic device is proposed, which is configured to receive at least one cryptographic parameter and validate the at least one cryptographic parameter. The electronic device is is configured to validating the parameter by determining an imprint from a one-way function and from at least the cryptographic parameter; detecting at least one part of the imprint in a dedicated memory zone of the electronic device, and delivering a piece of information on validation should there be effective detection.

1. An electronic device comprising:
means for receiving at least one cryptographic parameter; and means for validating said at least one cryptographic parameter, wherein said means for validating comprises:
means for determining an imprint from a one-way function and from at least said cryptographic parameter; andmeans for detecting at least one part of said imprint in a dedicated memory zone of said electronic device, said dedicated memory zone comprising a preliminarily stored imprint, said means for detecting delivering a piece of information on validation if there is effective detection.
