Abstract

A method is for operating a cryptographic device to reduce effects of power analysis and time attacks. The method may include executing a first set of cryptographic algorithm computations with a first crypto-processor of the cryptographic device. The first set of cryptographic algorithm computations may provide encryption of a first set of data to be protected with a first secret key stored in the cryptographic device. The method may further include executing a second set of cryptographic algorithm computations with a second crypto-processor of the cryptographic device for providing encryption of a second set of data different from the first set of data to be protected with a second different secret key.
