Problems solved by technology

However, the security problems brought by this method to the cryptosystem cannot be ignored.
For example, the widely used RSA system, if only one key pair is used to implement encryption and signature, the originally secure encryption and signature system is no longer safe

Abstract

The invention relates to the technical field of telecommunication, in particular to an intelligent power grid safety communication method based on a combined password. The system comprises a pluralityof transfer stations, each transfer station is provided with an intelligent computing access module and a cloud module connected with the intelligent computing access module, and the intelligent computing access modules are used for acquiring information of power generation equipment, power transmission equipment, power distribution equipment and power utilization equipment and interacting the acquired information with the cloud modules. Each intelligent computing access module is correspondingly provided with a secret key system, and the cloud module is further connected with a second secretkey system. The method has the beneficial effects that the reliability, integrity, confidentiality and non-repudiation of information transmission are realized; the public key cryptosystem is used inthe smart power grid, so that the authentication and confidentiality of smart power grid communication are ensured, and the number of secret keys stored in the smart power grid is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of telecommunications, in particular to a method for secure communication of smart grids based on combined ciphers. Background technique [0002] As a product of the new era, the smart grid will completely replace the current grid architecture in the future and provide more reliable, safer and more convenient services for human life. A major feature of the smart grid is the realization of two-way communication between the user and the power company, so it can predict the energy demand of the user more objectively and avoid the waste caused by excessive power production. At the same time, with the increase and integration of communication, network loopholes in the smart grid also emerge as the times require. Realize smart stealing and smart tracking. One of the goals of the smart grid is to provide consumers with information about their energy consumption in near real-time. For example, consumers can get th...
