Abstract

The invention provides an offline card transaction authentication system and an offline card transaction authentication method. The user card records the asymmetric private key and balance information, and generates a symmetric conference key. The transaction authentication host includes a card reader coupled to a user card and generates a symmetric conference key. In response to the transaction instruction received by the transaction authentication host, the transaction authentication host and the user card perform an identity authentication program according to the symmetric conference key. In response to the user card passing the identity authentication program, the transaction authentication host performs a transaction specified by the transaction instruction with the user card, and the user card adjusts balance information according to the transaction. The user card generates a digital signature for a transaction record of the transaction by using the asymmetric private key, and stores the digital signature and the transaction record in the storage medium.
