1. A security access and management control method of OCF equipment based on asymmetric cryptographic algorithm is characterized in that the method only generates a group of public and private key pairs by an OCF client, and runs a public key method by an OCF server;

  • in the data interaction process, a control instruction of the OCF client is encrypted by using a private key of the client, and is decrypted by using a public key after being sent to the OCF server;

    the data reported by the OCF server are encrypted by using a public key of the client, and are decrypted by using a private key after being sent to the OCF client;

    a public key in a public-private key pair generated by the OCF client is distributed to an OCF server which needs to be accessed and controlled by the client through a handshake protocol, and public key information is stored in the oic/security resource of the OCF server;

    carrying out public and private division on resources of an OCF server, wherein for common resources, all clients have control right and can receive data of the resources;

    for the private resources, only the client with the key pair can correctly control and acquire the data of the private resources;

    other clients want to control the private resource, and need to apply for the client with the key pair, and obtain the key after obtaining the authorization, to access the private resource.
