Abstract
This paper reflects the achievement of improved results in terms of cost for Pipelined Crypto Modular Multiplier Architecture when compared with its earlier versions of Parallel Crypto Architecture. The improved pipelined modular multiplier is implemented on Field Programmable Gate Array (FPGA), designed in four stages to be properly suitable for elliptic curve crypto computation. To avoid inversion complexity, the elliptic computations arithmetic utilizes projective coordinates instead of the normal affine coordinates. We adjusted the elliptic curve crypto addition operation with efficient scheduling for this pipelining.
The proposed hardware is compared to the previous parallel (non-pipelined) models that were similarly designed. All considered architectures have been synthesized for 160-bits operations showing interesting features. Detailed results showed that this work gave overall efficiency in the cost, which shows a promising direction for further research.
