In last decade of the twentieth century electronic gadgets penetrated our lives in huge numbers. During the development of such technologies operation of the devices/protocols was the main concern and the security aspect was ignored. But the losses that occur due to security breaches resulted in security conscious designs. The direction of technological advancement is also towards more functionality in less area. In such cases security is usually the last preference. There is also more advancement in chip fabrication per unit area that brings the concept of system on chip (SOC). So to take the advantage of small fabrication per unit area for security enhancement we propose the architecture of modular arithmetic unit (MAU) as part of the new SOC in order to implement cryptographic algorithms in an efficient manner. MAU is designed keeping in view ease of interfacing with any processor on SOC. Thus cryptographic algorithms that are based on modular arithmetic can be written in high level language and executed on processor of SOC. MAU is implemented on Xilinx Spartan 3 which shows flexibility, scalability and less area. The implementation results show area consumption of 1500 slices.
