Abstract: This paper studies the data encryption model and encryption method of the connection-oriented computer network communication system. Firstly, the application and security analysis of digital certificate and big integer decomposition encryption algorithm in connection-oriented are studied. Secondly, in the design of encryption communication module, a new hybrid encryption mechanism is proposed, that is, a strong and fast encoding algorithm is used to encrypt the plain text, Rivest-Shamir-Adleman (RSA) algorithm is used to encrypt the key, and Secure Hash Algorithm (SHA) algorithm is used to generate the digital abstract. Finally, an improved cryptographic model of elliptic curve cryptosystem is constructed, and an effective exclusive form of node private key is obtained. The experimental results show that the improved algorithm can simplify the deployment and improve the efficiency of the cryptographic system in large-scale public key certificate system.

Keywords: network communication; digital certificate; digital signature; encryption algorithm; encryption optimisation; improved cryptographic; private key; key certificate; connection-oriented; decomposition.
