语音实验室端到端即时通信认证协议设计OA北大核心CSTPCD

A design method for speech laboratory end-to-end instant messaging authentication protocol based on mixed encryption and decryption is proposed to ensure the security of end-to-end instant messaging and ensure that the voice content is not eavesdropped or tampered with.The RSA method is used to encrypt and decrypt the instant messaging session key transmitted by the sender.The 3DES method is used to encrypt and decrypt the plaintext voice information sent by the sender.During the process of encryption and decryption,the encrypted information is packaged into an encrypted packet and sent to the information receiver.After obtaining the encrypted packet,the information receiver uses RSA(Rivest-Shamir-Adleman)method and 3DES(triple data encryption algorithm)for effective key decryption authentication and plaintext voice message decryption,so as to obtain end-to-end plaintext voice information from the voice laboratory.The experimental results show that the authentication acceleration ratio of end-to-end instant messaging in the voice laboratory is improved after the implementation of this protocol,and only when the key input content is accurate,the information receiver can obtain accurate plaintext voice message content without any content distortion.
