ActiveCN109472166AReduce tamperingReduce riskFinanceDigital data protectionThird partySignature file
An embodiment of the application discloses an electronic signature method. An electronic device signs a seal file by using a private key to obtain a signature file, and generates a signature file digest according to a digest algorithm and the signature file. A signature information digest is generated according to the signature information and the digest algorithm. The signature information includes at least a signature file, a signature file digest and a digital signature certificate. The signature encryption information is generated by encrypting the signature information and the signature information digest with the public key of the third party fair organization, and the signature encryption information is stored in the block chain network. The signature encryption information is generated by encrypting the necessary information generated in the process of electronic signature with the public key of the third party fair organization, which ensures that other organizations or individuals except the third party fair organization can not decrypt the signature encryption information privately, and reduces the risk of information being tampered with or stolen; The signature encryption information is stored in the block chain network with anti-tamper mechanism, which ensures the authenticity and security of the information.

The invention discloses a method for hierarchichal onion rings routing. The nodes in a wireless Mesh network are divided into a gateway G, trusted nodes OP (Onion Proxy) and normal nodes Fi, wherein, the trusted nodes OP and the gateway G are induction nodes; the trusted nodes OP serve the function of selecting a route during the initialization of the ring; and the assembly of all the trusted nodes OP and the gateway G constitutes an anonymous assembly. The onion routing of the network is divided into two loop layers, wherein, the first route layer is a loop route consisting of the non-adjacent trusted nodes OP and the gateway G of the anonymous assembly; and the second route layer is a loop route formed by filling normal nodes Fi among the trusted nodes OP, and the second route layer is randomly selected by the trusted nodes OP and the gateway during the initialization. Accordingly, the anonymous and secure communication in the Mesh network can be achieved by the layered loops of the onion rings route. By using the layered onion rings communication protocol and allowing the trusted nodes OP and the gateway of the anonymous assembly to select the route together, the invention can effectively mix up the paths and prevent the intersection attacks, thereby reducing the computation, alleviating the load of the gateway, accelerating the ring construction, preferably utilizing the network resources to reduce delay.
