ABSTRACT:
A mutual certification method includes an IC card having a random number generator, a plurality of key data and a plurality of encryption algorithms, and an IC card terminal which also has a random number generator, a plurality of key data and a plurality of encryption algorithms. The key data and encryption algorithm to be used are designated, and a random number may be transmitted for encryption and return, so that mutual certification may be performed.
