Embodiment one: fig. 1 is a flowchart of a secure communication control method based on the internet of things according to an embodiment of the present invention, where the method may be implemented by the secure communication control system based on the internet of things according to the embodiment of the present invention, and the system is composed of a plurality of software and hardware modules, as shown in fig. 1, and the method specifically includes the following steps:
s101, performing management control of a gateway and bypass networking of a virtual private cloud system;
in the embodiment of the invention, the gateway operation optimization management is carried out on the virtual private cloud system, so that the management control of the controlled device and the abnormality monitoring of the virtual private cloud is realized; in the step, the control gateway receives the command sent by the controller and executes corresponding operation to monitor other service states on the gateway, meanwhile, other programs are guaranteed to be normally started through abnormal monitoring, after the conditions of process exit, network abnormality and the like occur, the starting process is controlled and the network configuration is restored, the normal operation of the system is guaranteed, meanwhile, the gateway controller is further started to be responsible for carrying out safety communication with the controller, VPN configuration information and network configuration information are firstly obtained from the controller, corresponding configuration files are generated, then data of the networking gateway are forwarded to other networking gateways through a data tunnel of networking service, through the processing, the gateway operation of the virtual private cloud system can be more efficient and stable, the working efficiency of the virtual private cloud is improved, and the follow-up safety processing is facilitated.
After the optimization management of the gateway is completed, forwarding data of target services of the virtual private cloud system through bypass networking; according to the method, firstly, according to the condition that a public network IP and port mapping are provided by a user, a secure access gateway is deployed on a private cloud core switch which is required to be accessed by a bypass by the user, a VPN server is deployed on the secure gateway and used as a data server for accessing the private cloud network, a VPN client is deployed on a gateway of the user bypass network, an intranet NAT rule of the gateway is configured, data accessing the bypass is led into a VPN data channel for forwarding, then for the condition that the public network IP is not provided by the user, the VPN server is deployed on the public cloud and used as a data forwarding server, meanwhile, a GRE tunnel is configured on the VPN data channel of the gateway for IP penetration, static routing is further configured, intranet data is forwarded to the GRE tunnel, bypass access is realized, and the data transmission flexibility of the virtual private cloud is improved.
S102, carrying out data storage management of the virtual private cloud through a database table;
illustratively, in an embodiment of the present invention, the design database table provides a classified storage management service for data of the virtual private cloud; in the step, a gateway information table, a project table, a link table, a public routing table and a private routing table are respectively established through a database table and used for classifying, storing and managing the data of the virtual private cloud, specifically, the gateway information table comprises: the method comprises the steps of storing gateway MAC addresses, WAN network segment information, LAN network segment information, expiration time, link configuration, virtual IP, access control rules, private routes and the like, wherein a project table is a collection of gateways and is used for managing the gateways in the same group of networks, a field comprises project names, project descriptions, creation time and the like, a link table is a collection of a plurality of resources, one link comprises a plurality of resources, when the gateway binds the link, the resources can be switched to other resources when the resources are unavailable, the stability of the service is ensured, a public routing table stores routing information which needs to be loaded by all the gateways under the project, and a private routing table stores routing information which needs to be loaded by a single gateway.
S103, carrying out security management analysis on the virtual private cloud system;
in the embodiment of the invention, the type of the data packet is judged according to the protocol header, and session management analysis of the virtual private cloud system is carried out; because the communication protocol header mainly comprises four types of data packets, ox01 represents a key negotiation stage, ox02 represents a gateway authentication data packet, 0x03 represents a transmitted user data packet and Ox04 represents a heartbeat packet, in this step, session management determines the role of the data packets according to the identification of the protocol header, and processes the data packets of different protocol headers differently according to a set rule, wherein a timeout session deletion mechanism is set for a session with abnormal network communication, so as to prevent the situation that network ports are occupied or the session is full and service cannot be provided, the judgment basis of session timeout is the number of times of successful heartbeat packet reception, if the server does not receive the heartbeat packet sent by the client beyond the set number of times, the server judges that the session is overtime, deletes the connection from a session list, and releases related resources, thereby indirectly improving the operation safety and smoothness of the virtual private cloud system.
Performing session key control management between the server and the client through key negotiation; in the step, after receiving a key negotiation data packet and analyzing the key negotiation data packet, a controller generates a session ID and stores the session ID, and further calculates a new nonce value according to the session ID and the received client nonce value, then invokes a public-private key generation algorithm to generate a public key and a private key, signs a protocol header, the nonce value, the session ID and the public key by using the private key, sends the signature to a controlled terminal after the signature is completed, and after receiving the signature, the controlled terminal performs signature verification according to the obtained public key and other information, and after the verification passes, the controller completes a key negotiation process, and through the process, the session safety between the server and the client can be effectively improved.
After the key agreement process is completed, the gateway sends the encrypted authentication data packet to the controller to carry out gateway identity authentication processing; in the step, after receiving the encrypted authentication data packet, the controller firstly inquires whether the gateway information exists in a local database, judges whether the gateway is out of date or not and is disabled or not, if the gateway is not out of date or not, the authentication packet constructed according to the user name and the password is sent to an authentication server for authentication, the authentication result is returned to the gateway after being encrypted, if the gateway does not exist in the database or the gateway is expired, the gateway directly returns an authentication failure data packet to the gateway, and the gateway terminates the process of establishing a security channel; the security of the virtual private cloud system can be greatly improved through the processing, and the security of the user privacy is effectively protected.
S104, performing data encryption and log summarization control processing;
illustratively, in the embodiment of the present invention, after receiving a data request packet sent by a slave, a controller encrypts a plaintext of a query result and sends the ciphertext to the slave; the encryption parameters are parameters generated in a key negotiation stage, and the data transmission security of the virtual private cloud system can be effectively improved through the processing.
