Abstract
In one embodiment, data communication apparatus includes a network interface for connection to a network and configured to receive a sequence of data packets from a remote device over the network, the sequence including data blocks, ones of the data blocks having block boundaries that are not aligned with payload boundaries of the packets, and packet processing circuitry to cryptographically process the data blocks using a block cipher so as to write corresponding cryptographically processed data blocks to a memory, while holding segments of respective ones of the received data blocks in the memory, such that the packet processing circuitry stores a first segment of a data block of a first packet in the memory until a second packet is received, and then cryptographically processes the first and second segments together so as to write a corresponding cryptographically processed data block to the memory.
