Abstract

The invention provides an intelligent IC card personalized data writing method, a computer device and a computer readable storage medium. The method comprises the steps that a card writing terminal obtains user personalized data, the personalized data of users is sent to a first discrete generator; the discretely encrypted user personalized data sent by the first discretization generator is received, the card writing terminal converts the discretely encrypted user personalized data into a personalized APDU instruction sequence; the personalized APDU instruction sequence is sent to an intelligent IC through the security channel, and after the intelligent IC card obtains the personalized APDU instruction sequence, user personalized data obtained after discrete encryption is extracted, and the user personalized data obtained after discrete encryption is sent to the second discrete generator. The user personalized data written into the intelligent IC card in the personalized process of theintelligent IC card can be discretely encrypted, so that the security of the user personalized data is improved.

Description

technical field [0001] The invention relates to the technical field of smart cards, in particular to a method for writing personalized data in an intelligent IC card, a computer device for realizing the method, and a computer-readable storage medium. Background technique [0002] When personalizing a smart IC card such as a financial IC card, it is necessary to obtain user personalization data through a card writer, and then convert the user personalization data into a personalized APDU command sequence and send it to the smart IC card for personalization processing. Under normal circumstances, the user's personalization data will have key data and corresponding verification values. Among them, the key data is encrypted and written into the smart IC card, and the verification value of the key is written into the smart IC card in plain text. . [0003] Since the method of opening and writing the secure channel between the smart IC card and the terminal, the algorithm for enc...
