A cryptographic packet processing unit performing cryptographic operations on a data portion of a data packet based on control information included in a header of the data packet. The cryptographic packet processing unit comprises a cryptographic bus interface unit, a crypto-processing unit, and a control storage unit. The cryptographic bus interface unit is capable of (i) receiving the data packet and (ii) removing the control information from the data portion. Coupled to the cryptographic bus interface unit, the crypto-processing unit is capable of performing a cryptographic operation on the data portion under the control of the control storage unit, which contains the control information.
