Abstract

The invention provides a method and a device for detecting an encryption algorithm and a secret key. The method comprises the steps of identifying a detected terminal and obtaining the type of the detected terminal and password equipment used by the detected terminal; determining the detected algorithm type according to the password equipment used by the detected terminal; for the detected algorithm type, selecting a set correlation calculation example to carry out calculation, comparing the detected algorithm type with a cipher-text generated after the detected terminal carries out password calculation according to an input plaintext, and generating the detection result of the detected algorithm type; obtaining the length, the strength, the life cycle and the interaction protocol of the secret key used by the detected terminal, carrying out password calculation according to the set technical specification, and generating the detection result of the secret key. The method can automatically identify the algorithm used by terminal equipment, and checks whether the algorithm conforms to the specification of the national password authority, the device is compatible with all types of interfaces, compliance inspection of use of the encryption algorithm and management of the secret key is carried out on the terminal, and terminals breaking the rule and illegal terminals are prevented from being accessed.

Description

technical field [0001] The present invention relates to encryption technology, in particular to a detection method and device for encryption algorithm and key, in particular to a unified encryption algorithm and key detection method and device for business applications of power grid enterprises. Background technique [0002] Encryption technology is the core technology in the field of information security. It can effectively solve the confidentiality, integrity and authenticity of information. In the context of the current highly informatized power business and the continuous popularization of smart grid technology, more and more power equipment is gradually becoming intelligent. The information interaction data in power companies, especially power grid companies, shows a geometric progression. Encryption technology is used to protect them. The key data has become an urgent problem to be solved. [0003] The use of encryption technology has penetrated into all aspects of t...
