Abstract

The invention provides a trusted platform module TPM system structure and a method of providing service. The structure comprises an I / O bus interface module, a password coprocessor module, an HMAC engine module, an SHA-1 engine module, an Opt-In module, a nonvolatile memory module, a volatile memory module, an execution engine module, a power-detecting module, a random number generator, a key generator module and an I / O interface module for special information; wherein, interaction operation is performed internally for the I / O interface module for special information and the execution engine module; preset, backup and recovery of internal information for trusted platform module are performed through the connection with each parallel or serial trusted equipment and the function of pin PP is replaced. The trusted platform module provides the following services: reading identification information of connected equipment for I / O interface module for special information; testing status of I / O interface module for special information; presetting initial information, moving information, backing up or recovering TPM sensitive data. The invention can be used for enabling safe operation of internal sensitive information of TPM module.

Description

technical field [0001] The invention belongs to the technical fields of computer security and network communication, and in particular relates to the system structure of a trusted platform module and a method for providing services thereof. Background technique [0002] Since the 1980s, the personal computer industry has developed rapidly with the concept of compatibility and openness, realizing the separation of computer software and hardware design manufacturers. The products of each manufacturer can be compatible and run with each other while having their own characteristics. The Internet is the largest computer network with the widest coverage in the world today. The rapid development of the Internet has brought about tremendous changes in the world economy, social development, and human life, as well as people's study, work, and lifestyle. Therefore, computers are widely used in various industries and families, which are the driving force behind the rapid development of...
