Embodiment Construction

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0019] This solution is based on an asymmetric encryption algorithm to realize the secure access and management control of OCF equipment. This solution only performs simple asymmetric encryption through all control instructions and data to achieve effective simplification while ensuring a certain level of security. The complexity of OCF device security control and data interaction implementation.

[0020] Specifically, this solution is different from the SSL implementation. Only the OCF client generates a set of key pairs, and the public key method is given to the OCF server, that is, the private key cPK in the key pair is saved by the OCF client, and the key pair The public key cPK_pub in is distributed to the OCF server that the client ne...

Abstract

The invention discloses an OCF equipment security access and management control method based on an asymmetric encryption algorithm. The method comprises the steps that a public key and private key pair is generated by an OCF client, and the public key is operated by an OCF server; in the data interaction process, a control instruction of the OCF client is encrypted by the private key of the client and decrypted by the public key after being sent to the OCF server; and data reported by the OCF server is encrypted by the public key of the client and decrypted by the private key after being sent to the OCF client. According to the scheme, on the premise that the data interaction security is guaranteed, the overhead of the OCF server is greatly reduced, and the achievement complexity of OCF equipment security control and data interaction is effectively reduced.

Description

technical field [0001] The invention relates to a network security technology, in particular to the security access and management control technology of OCF equipment. Background technique [0002] The OCF network consists of a client and a server. The OCF server is generally a limited device running on an embedded system. The OCF server node only needs to consume a small amount of resources to complete networking and data transmission. Because the node access conditions of the restricted device network are low, third parties can obtain the confidential information of the device with only a simple attack operation, which brings great economic losses to users. [0003] Currently, commonly used network security protocols are as follows: [0004] The SSL protocol using public key technology has become an industrial standard for secure communication on the Internet. The Secure Sockets Layer protocol enables user / server application communication to be protected from eavesdroppi...
