Design and application of blockchain power data transaction information protection based on paillier

Aiming at the problems of information protection in the current blockchain data transaction process, this paper proposes a blockchain transaction information protection method based on Paillier algorithm and RSA algorithm on the basis of the existing blockchain privacy protection scheme. Firstly, the nature of the additive homomorphism of the Paillier algorithm is used to design, and the complex operation that requires multiplication is proposed to use the multiplicative homomorphism characteristics of the RSA algorithm. Secondly, based on the current information protection scheme, the power data trading platform is designed to help solve the problem of power data transaction trust and promote the circulation and sharing of power data elements. Provide practical experience and inspiration.
