Secure chip key issuing system and secure chip key issuing method

Abstract

The invention provides a secure chip key issuing system and a secure chip key issuing method. The system comprises a chip key issuer, a chip key issuing mainframe, a key management server and a cipher machine. A certain improvement is made to the chip key issuer and the cipher machine, namely, in the chip key issuer, a chip key reading-writing mechanism is directly fixed on the chip key issuer, and a chip fixing device is embedded in the chip reading-writing mechanism to enable the chip fixing device to be directly in physical connection with a pin of an issued chip so as to effectively prevent information monitoring and key interception of the chip key issuer from the outside. In the system and the method, a secure chip and the cipher machine of the chip key issuer are supportive of the symmetric encryption technology and the asymmetric encryption technology and have a data encryption and decryption operation function, an SSL (safety session link) is established between the chip key issuer and a server cipher machine by performing session key negotiation through the symmetric encryption technology and the asymmetric encryption technology, and safety of a chip key issuing system is effectively improved.

Description

technical field [0001] The invention relates to the field of information security, in particular to a security chip key issuing system and method thereof. Background technique [0002] With the rapid development of computer and Internet technology, information security issues have become increasingly prominent, and encrypted transmission of key data has become the most fundamental means of security protection. However, the security of transmitted data depends not only on the encryption algorithm, but also on the security of the encryption key. Due to the serious defect of poor key security performance in software encryption, hardware encryption has become a new choice. At present, various encryption chips are already on the market, but the safe issuance of keys in encryption chips is still a key issue. The traditional chip key issuance process is as follows: first, the operator logs into the PC to select the business application module according to the business needs, and ...

AI Technical Summary

Problems solved by technology

Since the key is transmitted between the PC and the key issuing machine in the chip key issuing system, and the communication between the key issuing machine and the encryption chip is mainly through the network, it is easy for attackers to use technical means such as eavesdropping, monitoring, or deciphering. Obtaining key information has a great security risk
