Efficient Parallel-Pipelined GHASH for Message Authentication

WebNow, we attack this protocol with a quantum circuit of the hash function. Take a superposition over all possible inputs x i and query the hash function with this state to obtain the state ψ = ∑ i x i H ( x i) . Measure the second register to obtain a random commitment. The measurement randomly picks c = H ( x i) for some i. Webalgorithm that is specified in Federal Information Processing Standard (FIPS) Pub. 197 [2].
