The invention provides a reconfigurable trusted cryptographic module simulator, an implementation method and a simulation reconstruction method. The invention aims to solve the technical problem that an existing simulator cannot perform function expansion and function adjustment for an application scene. The implementation method comprises the following steps: forming a set of functional sub-modules of a core algorithm in an encryption and decryption process; forming a definable storage structure of associated information of the functional sub-modules; and forming a message sequence among the determined function sub-modules according to configuration data, forming a determined message transmission route of the associated information through the message sequence, and forming a determined encryption and decryption process through the determined message transmission route. According to the method, based on a message driving mode, the simulator is split into a reconfigurable and replaceable functional module set, the configuration data templated processing capacity of an internal data structure of the simulator is provided through a software definition data structure method, the internal structure and command format of the simulator can be realized and modified in a software definition mode, and the simulator is ensured to have good compatibility and expansibility.
Description
technical field [0001] The invention relates to the field of encryption technology, in particular to a reconfigurable trusted cryptographic module simulator, a realization method and a simulation reconstruction method. Background technique [0002] Trusted computing is the security guarantee for the trusted operation of information systems. It is based on cryptography, uses trusted chips as the source of trust, and guarantees the credibility of information systems through trusted chains. The national standard stipulates that the trust starting point of a trusted system is a trusted cryptographic module (TCM) with trusted cryptographic functions. The trusted platform module (TPM) in the international standard can also meet the requirements of TCM in terms of functions. [0003] To facilitate the development and testing of trusted cryptographic functions, trusted cryptographic module simulators are generally designed to simulate trusted cryptographic modules of specific stand...
