The Design Of Smart Card Data Security Technology Research And Rsa Key Generation

Data security technologies used in smart card are researched ,and a RSA key generator integrated in smart card is designed. The RSA key generator is made up of two parts: random number generator (RNG) and the implementation of RSA key generation algorithm. The RNG is realized which using switch capacitor circuits ,and based on chaos. Although the RSA key generation algorithm itself is certain, the algorithms used in each step of RSA key generation algorithm are optional. By carefully analyzing and comparing these algorithms under the condition that used for smart card, the optimum algorithms are choiced, and the RSA key generation algorithm is implemented in smart card. The designed RSA key generator can generate a pare of 1024 bits RSA keys within 30 seconds (average value ) .
