Problems solved by technology
[0006] Existing schemes or public key management in mobile ad hoc networks need to rely on online trusted third parties, which are not suitable for the self-government characteristics of mobile ad hoc network nodes, or key management operations are too costly and inefficient
In addition, there is no effective certificate revocation mechanism in the public key management of mobile ad hoc networks, and the security control of certificates needs to be improved

Embodiment Construction
[0031] Please refer to figure 1 , the embodiment of the present invention provides an autonomous public key certificate management method, which is applied to a system including multiple network nodes and offline management devices, and the method includes the following steps:
[0032] Step 101, the network node performs identity authentication through the offline management device.
[0033] Step 102, the network node whose identity has passed the authentication requests the offline management device to issue a certificate stub for it.
[0034] Step 103, the network node autonomously generates and manages the public key certificate according to the certificate stub.
[0035] After step 103, it also includes that during the use of the public key certificate, the network node can pass its public key certificate to the verification node, and the verification node can verify the validity of the certificate; the network node can also update or revoke its own public key when necess...

The embodiment of the invention discloses a method, a system and equipment for managing an autonomic public key certificate, which are applied to a system comprising a plurality of network nodes. The system comprises offline management equipment. The method comprises the following steps that: the network nodes perform identity certification through the offline management equipment; the network nodes with approved identity certification require the offline management equipment to sign and issue certificate counterfoils for the network nodes; and the network nodes generate a public key certificate according to the certificate counterfoil which is signed and issued by the offline management equipment. Under a distributed and autonomic environment, the method, the system and the equipment sufficiently consider the provisionality and the application-oriented characteristics of a network without the support of a fixed online reliable third party, realize the autonomic generation, the distribution, the certification, the refreshing and the cancel of the public key certificate of the nodes.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to an autonomous public key certificate management method, system and equipment. Background technique [0002] MANET is a wireless mobile multi-hop network that does not depend on any fixed infrastructure. In addition to mobility and self-organization, mobile ad hoc networks often have complete distribution, node autonomy and temporary. Specifically, there is no fixed infrastructure in the mobile ad hoc network to provide services for other nodes, and all nodes in the network are equal. In order to complete a task, nodes often need to cooperate with each other (complete distribution); Each node manages and controls its own resources completely autonomously, and decides its own behavior (autonomy); mobile ad hoc networks are often temporarily and urgently established for a special purpose, because most of the nodes in the network are mobile devices, Energy is often l...
