Comparison of ECC and RSA algorithm in multipurpose smart card application

The main role of encryption algorithms is to keep devises safe from attack. Using the best and more efficient algorithm for a device according to its storage and amount of data transfer is the most important part. This paper compares Elliptical Curve Cryptography algorithm (ECC) with RSA algorithm on a multipurpose smart card. There are three applications in our multipurpose smart card which is named health, credit and passport card. ECC is compared with 160 bit key size and RSA with 1024 bit key size. The result of comparison is described in the final section.
