Abstract

The invention discloses a payment terminal offline authorization method and system based on an IC card. The method comprises the following steps of: obtaining a target object, the payment terminal cancompare whether the decrypted random number is consistent with the generated random number of the associated RSA public key value or not, and when it is compared that the decrypted random number is consistent with the generated random number of the associated RSA public key value, the payment terminal can record offline authorization information in an IC card to complete offline authorization. Through the above mode, the safety operation of the payment terminal can be authorized in an offline mode.

Description

technical field [0001] The invention relates to the technical field of payment terminals, in particular to an IC card-based payment terminal offline authorization method and system. Background technique [0002] As a financial transaction tool commonly used in daily life, payment terminals require high security, and operations related to the security of payment terminals must be authorized before they can be used. [0003] At present, many manufacturers use the online method to authorize the security operation of the payment terminal. Although this method is highly secure and the operation records can be traced back, each authorization must be connected to the Internet for communication, which requires the payment terminal itself to have a network function or configure a Computers with networking capabilities, and in addition, it is inefficient when the number of payment terminals that need to be authorized is relatively large. In addition, the online authorization method r...
