Description
Technical field
The present invention relates to IC card field of encryption, and in particular to a kind of IC card encryption method, device, terminal and storage medium.
Background technique
IC card (Integrated Circuit Card, integrated circuit card), also referred to as smart card (Smart card), wisdom
Card (Intelligent card), microcircuit card (Microcircuit card) or chip card etc..It is by a microelectronics
Chip insertion meets in the card base of 7816 standard of ISO, is made into card form.Communication modes between IC card and reader can be with
It is contact, is also possible to contactless.IC card is divided into Contact Type Ic Card, non-contact IC and double interfaces according to communication interface
Block (being provided simultaneously with contact and contactless communication interface).
The advantages that IC card is due to its intrinsic information security, easy to carry, fairly perfect standardization, authentication,
The fields such as bank, telecommunications, public transport, parking lot management are just more and more applied, such as China second-generation identity card, the electricity of bank
Sub- wallet, the SIM cards of mobile phones of telecommunications, the bus card of public transport, subway card all exist for collecting the parking card etc. of parking fee
It plays an important role in people's daily life.
Existing encrypting IC card, especially access card are easy to be replicated privately by user by personal equipment, cause to be difficult to
Management, therefore, how effectively card inside information to be prevented to be replicated, or effectively identify the card being replicated be IC card application field urgently
Technical problem to be solved.
Summary of the invention
Present invention solves the technical problem that the problem of being easily unauthorized copying for encrypting IC card, provides a kind of IC card encryption side
