Abstract
A method for checking cryptographic secrets for equality involves at least one of the secrets being stored in a read-protected manner in a secure system. The at least one secure system has a cryptographic hash value interface. For checking purposes, a hash value of the secret provided with a salt or with the hash value of a salt is output via the interface for comparison with a corresponding hash value of another secret provided with the salt or with the hash value of the salt.
