Security equipment, encryption machine, security equipment operating system and operation method

Abstract

The invention provides security equipment, which comprises a chip. A first arithmetic unit is arranged in the chip. Annual ring data of previous-time operation or initial annual ring operation is stored in the chip. The first arithmetic unit can perform first-time arithmetic operation to generate first authentication data. Data participating in the first-time arithmetic operation comprise operating data of this time and the annual ring data of the previous-time operation or the initial annual ring data. The security equipment can transmit the first authentication data and the operating data of this time to an encryptor corresponding to the security equipment for authentication. When the first authentication data passes the authentication of the encryptor, the first arithmetic unit can perform second-time arithmetic operation to generate annual ring data of operation of this time. Data participating in the second-time arithmetic operation comprise counter data of operation of this time and the annual ring data of the previous-time operation or the initial annual ring data. The invention additionally provides the encryptor, a security equipment operating system and an operating method. The security equipment provided by the invention has very high security and is not apt to clone.

Description

technical field [0001] The present invention relates to the field of security devices, in particular, to a security device, an encryption machine corresponding to the security device, a security device operating system including the security device and the encryption machine, and an operating system for operating the security device. How to operate the security appliance operating system. Background technique [0002] Current security devices (for example, bank cards or shopping cards, etc.) mostly store personal information such as personal identification numbers, keys, and digital signatures. This personal information is used to authenticate the security device holder, or said personal information may be used to calculate certain check figures when performing operations. [0003] After the security device is issued, the personal information written into the security device cannot be changed. However, since the personal information appears in the link during the operation,...
