A secure communication method and system based on machine chat

Abstract

The invention discloses a secure communication method and system based on machine chatting. By establishing a secure communication key between a user and an intelligent body to be communicated, when the user establishes a chat communication with the intelligent body, the intelligent body randomly selects the key from the secure communication key Extract a number of secure communication keys from the key and send them to the user for identification. When the user answers all the received secure communication keys correctly, it is confirmed that the user is the correct chat partner. Otherwise, the agent ends the communication with the user, and uses the user and The secure communication key established between the agents is used as a chat object verification mechanism, which does not require third-party security authentication and is safe and reliable. The secure communication key between the agent and the user is initially set by the user and randomly generated. The secure communication key is used to transmit communication to prevent it from being stolen. During the communication process, a new secure communication key can be formed, which can greatly improve the communication security of the agent, and can achieve a balance between ease of use and security, and has good robustness.

Description

technical field [0001] The invention belongs to the field of intelligent body security, and in particular relates to a secure communication method and system based on machine chat. Background technique [0002] With the development of artificial intelligence and the Internet of Things, humans can chat with smart machines and perform remote control, which brings a lot of convenience to industrial production and home life. The security of communication mainly adopts symmetric encryption technology to encrypt content, and uses asymmetric encrypted public key and private key technology to encrypt passwords to ensure. In theory, there are security loopholes in the distribution of public keys and the control of machines, that is, any illegal intelligence Any entity can generate a pair of public key and private key, and issue the public key to pretend to be a legal person. The legitimate machine may also be controlled by illegal users such as hackers or by violence, resulting in il...

The security of communication mainly adopts symmetric encryption technology to encrypt content, and uses asymmetric encrypted public key and private key technology to encrypt passwords to ensure. In theory, there are security loopholes in the distribution of public keys and the control of machines, that is, any illegal intelligence Any entity can generate a pair of public key and private key, and send out the public key to pretend to be a legitimate person. The legitimate machine may also be controlled by illegal users such as hackers or by violence, resulting in illegal communication and content theft.
