Abstract: Based on analyzing the structure character of Elliptic Curve Cryptography(ECC) algorithms, the representative operation is selected. This paper has a research on the parallelism among the operation. A solution for efficient cryptographic processing through two multiplication modules and two addition/subtraction modules are proposed. A Very Long Instruction Word(VLIW) architecture of ECC coprocessor with specific instruction set is also presented. Experimental result shows that this co-processor has tradeoff between high performance and flexibility.
