Abstract
An 8-bit bit-slice TEA-cryptographic accelerator for 64-bit RSFQ secure coprocessors is proposed. The accelerator is based on Tiny Encryption Algorithm (TEA) and mainly consists of bit-slice adders and bit-slice shifters. Synchronous concurrent-flow clocking is used to design a fully pipelined RSFQ logic design. For verifying the algorithm and the logic design, the RSFQ logic circuits of the proposed accelerator have been simulated with a target operating frequency of 50 GHz. It consists of 21 stages. The throughput is 7.672 × 107 64-bit TEA encryptions per second.
