Abstract:
With the popularization of computer network and intelligent terminal application,especially network finance and QR code,the problem of information security is becoming more and more prominent. DES,the data encryption standard of symmetric encryption algorithm,is studied,and PKI,the public key infrastructure system,is mainly studied, which is a third-party platform to ensure the security of information during transmission. It is mainly responsible for issuing certificates with CA central digital signatures and managing the public and private keys required in RSA algorithms. Several asymmetric encryption algorithms are studied and their performance is analyzed. We focus on the elliptic curve discrete logarithm algorithm and RSA asymmetric encryption algorithm based on the finite domain in CEE, and propose a private key encryption public key decryption scheme to solve the problem of authentication of authenticity of information,namely identity authentication. The programming implements RSA’s public key generation and encryption and decryption of information. It mainly implements three modules:RSA key generator module,encryption module,and decryption module. A encryption and decryption graphical interface is designed to complete file path encryption and the entire file encryption. Experiment shows that RSA algorithm is feasible and safe.
