Secure communication method and system based on machine chat

Abstract

The invention discloses a safety communication method and system based on machine chat, and the method comprises the steps: establishing a safety communication secret key between a user and a to-be-communicated intelligent agent, and enabling the intelligent agent to randomly extract a plurality of safety communication secret keys from the safety communication secret key and send the safety communication secret keys to the user for recognition when the user establishes chat communication with the intelligent agent; when the user answers all the received secure communication keys correctly, confirming the user to be a correct chat object, otherwise, the intelligent agent ends communication with the user, the secure communication key established between the user and the intelligent agent isused as a chat object verification mechanism, third-party security authentication is not needed, and the method is safe and reliable. The security communication secret key between the intelligent agent and the user is initially set by the user and randomly generated, the security communication secret key does not need to be transmitted for communication and is prevented from being stolen, a new security communication secret key can be formed in the communication process, the communication security of the intelligent agent can be greatly improved, the balance of usability and security can be realized, and the robustness is good.

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.
