Abstract

The invention provides a random number defect detection method and device. The method comprises the steps of controlling a random number generator to generate a plurality of random numbers when a random number defect needs to be detected, and obtaining the plurality of random numbers, then, determining a target defect type to be detected and random number defect representation characteristics corresponding to the target defect type, analyzing the plurality of random numbers based on the target defect type to obtain data characteristics of the plurality of random numbers, and finally, when thedata characteristics of the plurality of random numbers are matched with the random number representation characteristics corresponding to the target defect type, determining that the random number defect in a target defect type exists in the current environment. Thus, whether the random number generated by the random number generator has the data defect corresponding to the target defect type ornot can be accurately detected, the accuracy of random number defect detection is improved, and therefore the communication safety can be improved.

Description

technical field [0001] The present disclosure relates to the field of data processing, and in particular, to a random number defect detection method and device. Background technique [0002] Random numbers are the basis of cryptography, and passwords generated based on random numbers are widely used in communication between IoT devices. For example, among devices using Transport Layer Security (TLS) for communication, when the TLS protocol initiates communication, it is necessary to negotiate a communication cipher suite through a handshake, and then determine the symmetric encryption key in combination with a random number, and finally the server and the client The peers communicate through this key. [0003] If the random number used to generate the secret key is defective, it is easy for the secret key to be decrypted, tampered with, forged, etc., seriously affecting the security of communication. Therefore, there is a need for a technology that can detect random number...
