摘要：
A cryptographic system can include a register containing a key and a processor coupled to the register. The processor can be operable for performing a first encrypting operation, where the encrypting operation includes computing a key schedule using the register as a workspace. At the end of the first encrypting operation, the key is recovered from the register for use in a second encrypting operation.
