Microprocessor-aided portable data medium for exchanging data through a data exchange device runs an RSA encoding algorithm for creating a verifiable digital signature for a message

摘要

A program runs an RSA encoding algorithm for creating a digital signature for a message. The digital signature to be sent is verified. Only verified signatures are transmitted to the data exchange device. Verification exponents (e1,e2) are stored, serving to verify a digital signature by using a Chinese residual classes set.
