CSP (chip scale package) module of TSPI (telephony service provider interface) based on TSM (tivoli storage manager) and CSP implementation method

Abstract

The invention relates to a CSP (chip scale package) module of a TSPI (telephony service provider interface) based on a TSM (tivoli storage manager) and a CSP implementation method. The CSP module mainly comprises a CSP connection interface created by the TSPI on the basis of the TSM, a CSP key generating and exchange interface, a CSP encryption and decryption interface and a CSP hash and digital signature interface; the CSP connection interface is used for obtaining and cleaning a CSP key container, setting and obtaining container parameters and releasing the CSP key container; the CSP key generating and exchange interface is used for generating and destroying a key object by CSP, leading in and out the key object, loading the key object, obtaining and setting the key object parameters and generating a random number; the CSP encryption and decryption interface is used for carrying out CSP encryption and decryption; the CSP hash and digital signature interface is used for generating and destroying a hash object, obtaining and setting hash object parameters, signing and checking the signature. The interfaces are encapsulated on the TSPI of a TSM interface, therefore, an application developer can conveniently and safely develop TCM (terminal-to-computer multiplexer) application, and the traditional application is fast transplanted in the TCM conveniently at the same time.

Description

technical field [0001] The present invention relates to the field of trusted computing, in particular to the application of trusted computing technology to implement Microsoft CryptoAPI (an application programming interface provided by Microsoft Corporation, which provides a set of functions that allow applications to provide protection for sensitive private key data of users. A system and method for encrypting or digitally signing data in a flexible manner) encryption standard CSP (Cryptographic Service Provider, encryption service provider). Background technique [0002] Trusted Cryptography Module (Trusted Cryptography Module, TCM) is an essential key basic component of a trusted computing cryptographic support platform, which provides independent cryptographic algorithm computing functions and supports the establishment of a trusted computing platform functional system. [0003] TCM builds a subsystem with storage protection and execution protection, which establishes th...

AI Technical Summary

Problems solved by technology

[0005] When developers of traditional security applications turn to application development based on TCM cryptographic service functions, they need to relearn the TCM Cryptographic Service Invocation Interface System (TSPI). In addition, what’s more, to port traditional security applications to TCM, all Redevelopment brings resource consumption to application manufacturers, which brings great resistance to TCM application promotion
