Abstract :
The article presents a pipeline implementation of the block cipher CLEFIA. The article examines three known methods of implementing a single encryption round and proposes a new fourth method. The article proposes the implementation of a key scheduler, which is highly compatible with pipeline encryption. The article contains a detailed analysis of the data processing path for the 128-bit key version of the algorithm and verifies its operation on two FPGA cards in practice. On the basis of one of these cards, the article proposes a prototype of an effective supercomputer-compatible hardware accelerator (High Performance Computing Application).
