ABSTRACT:
A device for encrypting or decrypting data packets. The device includes two cryptographic elements. The first cryptographic element generates processing data, based on a first starting value, for use in cryptographically processing the data packet. The second cryptographic element is arranged to generate the first starting value based on a second starting value. The second starting value is based on a previously cryptographically processed data packet.
