摘要：Nowadays, secure information exchange is an important issue for the communication network. Ellipticcurve cryptography (ECC)s is a type of cryptography which can provide same level of security but with much shorterkey size. The main operation in ECC is scalar point multiplication in which a point on the curve is multiplied by ascalar. This scalar point multiplication is done through point additions and point doubling which in turn is done throughseries of multiplications, additions, and subtraction and division operations. Various ECC processors that target primefields, binary fields are there which depends on the modulus they take. In prime field ECC processors the carrypropagation can be limited by using the RSD based representation in which the digits are represented by difference ofits positive component and negative components. A modular adder unit along with a modular subtraction unit was donein which the RSD digits were given as the input .And also Karatsuba multiplier along with recursive and iterative wasdone. The same units were done with the CSD representation and a comparison of both representations was done.
