ASIP for Elliptic Curve Cryptography Based on VLIW Architecture

The requirement of the flexible and effective implementation of the Elliptic Curve Cryptography (ECC) has become more and more exigent since its dominant position in the public-key cryptography application. Based on analyzing the basic structure features of Elliptic Curve Cryptography (ECC) algorithms, the parallel schedule algorithm of point addition and doubling is presented. And based on parallel schedule algorithm, the Application Specific Instruction-Set Co-Processor of ECC that adopting VLIW architecture is also proposed in this paper. The coprocessor for ECC is implemented and validated using Altera's FPGA. The experimental result shows that our proposed coprocessor has advantage in high performance and flexibility.
