Abstract
Embodiments of an electronic circuit comprise a module, such as a security module, configured to perform cryptographic processing for a predetermined security protocol that includes random number checking. The security module is controlled by a descriptor that includes instructions that cause the security module to access a generated random number, compare the generated random number to a random number stored during a previous execution of the descriptor, and generate an error signal when the generated random number and the previous execution random number are equal.
