Abstract

The invention discloses an intelligent card safety communication method and relates to the field of information safety. The intelligent card safety communication method is capable of resolving the problem that communication data is monitored or intercepted. The intelligent card safety communication method is adopted and a safety communication mechanism capable of protecting an intelligent card to some extent can be provided. By launching a conversation, both communication sides are identified mutually, legality of identity of an opposite side and integrity of the communication data are confirmed, security constraint for follow-up communication is provided, and accordingly safety of communication is improved.

Description

technical field [0001] The invention relates to the field of information security, in particular to a method for secure communication of a smart card. Background technique [0002] With the rapid development of communication technology, information network has been widely used, and at the same time, computer network crimes are also emerging. People use identification and encryption technology to protect data in the information network, and widely use smart card products as identification tools for user identification. Safe and effective use of smart cards to realize real-time encryption and decryption processing of data transmitted in the network, so as to ensure that users can enjoy the services provided by the information network under the premise of safety, speed and convenience. [0003] For the security level involved in the field of information security communication, the currently used technology is not perfect, and it cannot avoid the problem of communication data b...
