Huizhong Liu, Suli Ge, Gaifang Tan, Song Tang · 2023
With the wide application of computer network and intelligent terminal, the application of blockchain technology is rapidly popularized, and the corresponding information security issues become increasingly important. This paper introduces the data encryption standard DES of symmetric encryption algorithm, and discusses the public-key infrastructure system PKI. It is a third-party platform to ensure the security of information during transmission, mainly responsible for issuing certificates with digital signature of CA center and managing public and private-keys needed in RSA algorithm. Several asymmetric encryption algorithms are studied, focusing on RSA asymmetric encryption algorithm, and the method of encrypting public-key decryption with private-key is designed and implemented to solve the problem of information authenticity identification, i.e., identity authentication namely identity authentication. RSA public-key generation, information encryption and decryption are designed, and RSA key generator module, encryption module and decryption module are realized. The results show that RSA algorithm is feasible and safe in blockchain scene.
