Problems solved by technology

[0007] With the evolution of the encryption algorithm, the group encryption algorithm encrypts the data in groups, which increases the difficulty of data decryption. However, a fixed encryption algorithm and key are used for encryption. After the encryption algorithm and key are determined, the plaintext and the password form a corresponding relationship , can be cracked by brute force methods such as brute force method, and the security needs to be improved

Abstract

The invention discloses a power line carrier communication system. The system can adaptively approach to an optimal frame length of an IPv6 packet slice in finite times, the complexity is low, the convergence can be carried out quickly to obtain the optimal frame length, and the IPv6 is efficiently supported; the system can generate a key according to personal information of a user, so that the key is unique and complex; and in a digital signal encryption and decryption process, bit operation is carried out on a plaintext digital signal, a user key and a first random digital signal to obtain a first ciphertext digital signal, meanwhile, the bit operation is carried out on the user key and the first random digital signal to obtain a second random digital signal, the bit operation is carried out on the obtained second random digital signal and the first ciphertext digital signal to obtain a second ciphertext digital signal, and finally reverse bit operation is carried out on the second ciphertext digital signal to obtain the original plaintext digital signal. The problem of poor confidentiality and security of the digital signal is solved, and the breaking difficulty is greatly increased.

Description

[0001] Technical field [0002] The invention relates to a power carrier communication system. Background technique [0003] The smart grid is a power transmission and distribution network using sound two-way communication, advanced sensors and distributed computing. Its purpose is to improve the efficiency of power transmission and use, and improve the reliability and security of the power grid. Establishing a high-speed, two-way, real-time, and integrated communication system is the basis for realizing the smart grid. At present, the main transmission means of distribution communication network are: optical fiber, public wireless network, self-built dedicated wireless network, power line carrier communication, power line frequency communication and other methods. [0004] Power line power frequency communication achieves data transmission by superimposing tiny distorted signals on voltage and current. Because low frequency power frequency distorted signals can pass through ...
