Temperature-assisted authentication system and authentication method thereof

Abstract

The invention discloses a temperature-assisted authentication system, which is characterized in that a controllable voltage and temperature adjusting module is additionally arranged in the authentication system to realize secondary authentication, the voltage and temperature adjusting module is additionally arranged, and the two parties respond to temperature change according to challenges, so that further encryption and decryption mapping is realized; and the auxiliary authentication effect is finally realized by depending on the internal authentication mechanisms of the two parties. Meanwhile, the invention provides a temperature-assisted authentication method, and compared with the condition that the environment temperature is difficult to control, the chip temperature can be effectively adjusted through factors such as voltage and frequency. The client and the server both adopt customized chips, perform data transmission and temperature adjustment according to authentication requirements of both parties, and further perform encoding and decoding, so that the data can be transmitted under specific conditions and serve as a part of security authentication, thereby realizing auxiliary physical encryption. Therefore, the capability of the authentication system for resisting relay attacks is enhanced, and the robustness of the system is very high.

Description

technical field [0001] The invention relates to the field of authentication protocols, in particular to an authentication auxiliary system for temperature-assisted authentication and an authentication method thereof. Background technique [0002] The traditional challenge-response authentication system encrypts and decrypts through encryption algorithms such as AES to protect the key from being stolen and impersonated, so that the server and the client can authenticate each other safely. However, the system is not assisted by encryption, and the relay attack easily leads to the leakage of the key, which greatly reduces the security of the system. [1] The environmental detection sensor is used to measure and compare the environmental physical quantities of both authentication parties, making it a part of the authentication system and assisting security authentication, which can reduce the risk of the system crashing after the relay attack and improve the robustness of the sys...

However, the system is not assisted by encryption, and the relay attack easily leads to the leakage of the key, which greatly reduces the security of the system. [1] Use environmental detection sensors to measure and compare the environmental physical quantities of both authentication parties, making it a part of the authentication system and assisting security authentication, which can reduce the risk of system crashes after relay attacks and improve the robustness of the system

However, the controllability of this auxiliary method is poor, it is completely dependent on objective factors, and the fluctuation of change is very small. If things go on like this, the reliability will gradually decline, and the probability of being attacked and cracked will greatly increase
