Traditional cryptographic algorithms are developed on a software platform and provides information security schemes. Also, some processors have performed one of the crypto algorithms (either prime field or binary extension field) on chip level with optimal performance. The objective is to design and implement both symmetric key and public key algorithms of a cryptographic on chip level and make better architecture with pleasing performance. Crypto-processor design, have been designed with unified field instructions to make different processor architecture and improve system performance. The proposed high speed Montgomery modular multiplication and high radix Montgomery multiplication algorithms for pairing computation supports the public key algorithm. This design has been developed using Verilog HDL’s and verified using ModelSim-Altera 6.4a, and it has synthesized with Xilinx 9.1 Integrated Synthesis Environment (ISE) tool
