Abstract

The invention belongs to the technical field of authentication security, and provides a CPU (central processing unit) card reader-writer based on full-dimensional public key authentication and a system authentication method. The CPU card reader-writer comprises a USB (universal serial bus) interface, a signal processing module, a public key module, an encryption module, a control unit and a digital signature module, wherein the signal processing module is respectively connected with the USB interface, the public key module, the digital signature module and the control unit, and the encryption module is connected with the public key module, the digital signature module and the signal processing module. The system authentication method comprises the following steps that programs are solidified in the public key module through the USB interface; a CPU card is put in a radio frequency part of the control unit; the control unit reads the user identification and the card number of the CPU card; the public key module calculates a CPU card public key; the encryption module encrypts the CPU card public key; the control unit carries out card writing on the CPU card. The CPU card reader-writer and the system authentication method have the characteristics that a full-dimensional public key authentication method is used, the secret key transmission is not needed, the security requirement in the communication process is not high, the use security is high, and the large-scale popularization and use are favorably realized.
