Abstract

A hash value computation device for computing a hash value for a message using a hash algorithm that defines a key is provided, the device comprising a message schedule element having an input module which receives the message in 8-bit segments, a plurality of 8-bit memory modules which store the 8-bit segments of the message, an 8-bit message schedule value module which uses the 8-bit message segments and the hash algorithm to provide an 8-bit message schedule value for each 8-bit message segment, and an output module which outputs the 8-bit message schedule values, and a hash value computation element comprising a first input module which receives the 8-bit message schedule values, a second input module which receives 8-bit segments of the key defined by the hash algorithm, a plurality of 8-bit memory modules which store the 8-bit segments of the key, a hash value computation module which uses the 8- bit message schedule values and the 8-bit key segments to compute a hash value for the message, and an output module which outputs the hash value.
