It encrypts data at more than 6.7 billion bits per second, 10 times faster than any other known encryptor. snip a superscalar implementation of DES (1 clock per round, 16 rounds of hardware) gives 6.7 Bps/64 bits per block or 104+ MHz clock. Should be able to do static key distribution accross the device, and 11 gate levels per round. That gives a number around 880 ps per gate with routing. Should be able to go 3 or 4 times faster. At least twice as fast with routing distances. You could also do a dual pipline... -- remove "no_spam_" from Reply-to address

(para 7.10) The paper further stated that "there has been remarkably little co-ordination of policy on encryption matters" internationally apart from the OECD Guidelines on Cryptography Policy. However, the Aaron Files that we are bringing to the attention of the public through these pages suggest otherwise - that UK Government encryption policy was closely co-ordinated by the US despite the denial in the Cabinet Office paper which concluded that the result of the absence of such a co-ordination "has been a degree of misunderstanding and suspicion as to the rationale behind attempts to regulate, or influence, the domestic use of encryption."

Your numbers are correct. You could put about a dozen fully-pipelined DES engines on an ASIC and get reasonable (e.g., commercial) yields. A 1-hour brute-force engine is the size of a laptop. Not counting SiGe.
