Realization and Application of RSA in Chip Operating System

摘要

As an outstanding asymmetric cryptography,RSA al gorithm has a lot of virtues and thus is well applied in the scope of IC card applications. T he paper deals with the application of RSA in smart cards and the approach in wh ich the modular exponentiation of huge number is simplified by using the Chinese Remainder Theorem. We have already succeeded in completing RSA in IC cards. Res ults indicate that RSA algorithm applied in IC cards has the equivalent speed of DES algorithm with the same environment.
