Abstract
The present disclosure relates to a method for decrypting encrypted data. The method includes generating a first count value by a monotonic counter of a processing device, deriving, using a key derivation circuit, a first encryption key based on the first count value, transmitting the first encryption key to a cryptographic processor; and decrypting, based on the first encryption key, first encrypted data.
