Abstract

The invention provides a smart card data processing method. The method comprises the following steps: exchanging a secret key between a smart card and a card reader, mutually authenticating identity by using a digital signature algorithm, and then using the secret key generated after exchanging to encrypt data transmitted between the smart card and the card reader. Through the adoption of the method provided by the invention, the authentication and data transmission processing between the smart card and the card reader are realized with low resource expenditure, the common attack can be resisted, and the expandability is provided.

Description

technical field [0001] The invention relates to smart card security, in particular to a smart card data processing method. Background technique [0002] With the continuous development of computer technology, smart cards are widely used as a fast and safe means. In the current process of developing the Internet of Things technology, as the main technology for identifying terminal objects, it has become an important part of the Internet of Things. An important reason for the rapid development of smart cards is that they can provide users with a higher security guarantee through the security system of the encryption system. By authenticating the smart card, the security status of the smart card can be obtained, and a certain usage authority can be obtained, so as to perform some security-related operations. [0003] In the contactless smart card system, the data exchange between the read-write device and the smart card is considered to be at risk of attack because it relies ...
