Abstract
An authentication device for a communication device includes key stream generator circuitry and hash function circuitry. The key stream generator circuitry receives a first input data stream and generates a first data stream output signal based on the first input data stream and an encryption key. The first input data stream is associated with a first data rate. The hash function circuitry receives the first data stream output signal from the key stream generator circuitry. The hash function circuitry includes first decimation circuitry and recursive circuitry. The first decimation circuitry receives the first data stream output signal, and combines adjacent data words of the first data stream output signal to generate a first decimated output signal having a second data rate. The second data rate is less than the first data rate. The recursive circuitry generates an authentication tag based on the first decimated output signal.
