| Popis: | The security of node ID assignment scheme is the foundation of solving security problems in structured P2P systems. However, existing researches on the node ID assignment mechanism present one or more following problems: (1) Schemes just only focused on individual attack, but did not comprehensively analyze the security requirements of node ID assignment mechanism. (2) Schemes needed complex certificate management or met key escrow problem. (3) Almost all existing schemes required a trusted center to act as the single signer of node IDs, but it is very hard to find an absolutely trusted node in structured P2P system. As a result, none of existing schemes can prevent the single signer from being compromised or launching active attack. This paper firstly designs a threshold signature scheme based on secret sharing and certificateless public key cryptosystem without paring (CL-PKC-without-P). Based on that, it proposes a node ID assignment protocol which eliminates the three problems listed above. Using secret sharing technology, this protocol is able to resist the active attacks launching by less than t signer, where t is the threshold value. The results of analysis and simulation show that this protocol is more secure, efficient and scalable. |
