Embodiment Construction

[0040] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0041] refer to figure 1 , figure 1 It is a schematic structural diagram of an embodiment of a system for testing RPMC in the present invention. In one embodiment, the system that RPMC is tested comprises: upper computer, lower computer and the storage chip that contains RPMC;

[0042] The upper computer is used to: receive user operations, and encrypt and calculate the first test command triggered by the user operation through the HMAC algorithm to obtain a first message authentication code, and perform the first test command and the first message Edit the authentication code to obtain a first message, and send the first message to the lower computer, where the first message is a message that can be identified by the communication interface between the upper computer and the lower computer;

[0043] In this exampl...

Abstract

The invention provides a system for testing an RPMC, and the system comprises an upper computer, a lower computer, and a storage chip containing the RPMC, and a user can operate on the upper computer,generates various test instructions, and transmits the test instructions to the storage chip containing the RPMC through the lower computer, so as to test the RPMC in the chip. Through the system, any test instruction can be flexibly generated based on user operation so as to carry out functional test or robustness test on the RPMC, and the system has the advantages of being flexible in test andcomplete in test case coverage.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a system for testing RPMC. Background technique [0002] The memory chip containing the enhanced mechanism of RPMC (Replay Protection Monotonic Counter) needs to communicate with the host during the development and verification phase to test the integrity and robustness of the RPMC function, and the host with this RPMC function is Intel Computer motherboards, mobile phones, etc., are all tested and verified through FPGA boards during the development stage, which prevents testers from randomly issuing test instructions to test RPMC. Contents of the invention [0003] The main purpose of the present invention is to provide a system for testing RPMC, aiming at solving the above-mentioned technical problems existing in the prior art. [0004] In order to achieve the above object, the embodiment of the present invention provides a kind of system that RPMC is tested, and described s...
