Apparatus and method for implementing interaction between applied system and security chip

Abstract

The invention discloses a device for realizing the interaction between an application system and a security chip. The device includes a security service providing module, a security core service module and a chip driver library. Because the device adopts a layered structure, it achieves the purpose of allowing different developers to customize different driving characteristics, and also supports interoperability between upper-layer software stacks developed by different developers. The present invention also discloses a method for realizing the interaction between the application system and the security chip. The call to the security chip is realized through the security service providing module, the security core service module and the chip driver library. Since the security service providing module can be installed in A host computer with a security chip can also be installed on a host computer without a security chip, thus realizing remote calling between the application system and the security chip, and each security chip can be used jointly by multiple users. Furthermore, the existence of the key database enables the security chip to store more keys.

Description

technical field [0001] The technical field of security chip management of the present invention particularly refers to a device and method for realizing interaction between an application system and a security chip. Background technique [0002] Today's society has entered the information age, and computer networks have gradually been used in various fields of society. With the advancement of national economic informatization and the rise of new network services such as e-commerce, society is increasingly dependent on computer networks. The information age calls for information security, and data encryption is a common method to protect data from illegal access. [0003] At present, the operation of key generation and encryption and decryption using hardware has the advantages of fast speed and difficult tampering, and has been widely used. Compared with pluggable hardware, the motherboard solidified security chip can provide cryptographic operations and at the same time au...

AI Technical Summary

Problems solved by technology

[0006] 1) Does not support driver features from different developers

[0007] 2) The security chip cannot be remotely accessed

Because remote access is very insecure, and existing interactive devices do not support remote access

[0008] 3) Since only the host with a security chip can access the security chip, each security chip can only be used by a few users. If the access authority of the same security chip is shared by multiple users, its secret information will not safe again
