Blockchain-based anonymous trusted voting method, apparatus and related device

A trusted anonymous voting device based on a blockchain, comprising:

• a memory, configured to store a program;
• and
• a processor, configured to execute the program to perform a trusted anonymous voting method, wherein the method comprises:
• deploying a voting service through Internet of Energy (IoE) that comprises a plurality of electronic voting devices;
• performing, by an electronic voting device of the plurality of electronic voting devices, a hash operation on original voting content to obtain a hash output, wherein the hash output comprises a commitment value cvi;
• blinding, by the electronic voting device, the commitment value cvi based on information of other voters to obtain a commitment value tuple {tilde over (c)} and a commitment value tuple {tilde over (x)}, wherein identity information of a voter is hidden through the blinding;
• signing, by the electronic voting device, the commitment value tuple {tilde over (c)} by using an elliptic curve digital signature algorithm (ECDSA) to obtain a signature tuple {tilde over (s)};
• and
• establishing, by the electronic voting device, a vote tuple ({tilde over (c)}, {tilde over (s)}, {tilde over (d)}) based on the commitment value tuple {tilde over (c)}, the signature tuple {tilde over (s)} and a signature tuple {tilde over (d)} of other voters, and uploading the vote tuple ({tilde over (c)}, {tilde over (s)}, {tilde over (d)}) and the commitment value tuple {tilde over (x)} to the blockchain, wherein the vote tuple ({tilde over (c)}, {tilde over (s)}, {tilde over (d)}) serves as voting content in a voting stage,
• wherein the signature tuple {tilde over (d)} is generated in response to successful verification by other voters on the signature tuple, and the commitment value tuple {tilde over (x)} is used to decrypt the vote tuple and
• collecting electronic votes by the plurality of electronic voting devices, wherein the vote tuple serves as one of the electronic votes,
• wherein the blinding the commitment value cvi, based on information of other voters to obtain a commitment value tuple {tilde over (c)} and a commitment value tuple {tilde over (x)} comprises:
• performing, for each of other voters, a point multiplication operation in an elliptic curve cryptography (ECC) on public key information pkj and {circumflex over (p)}kj of the voter to obtain a blinding factor tj;
• hashing the commitment value cvi based on the blinding factor tj to a new commitment value xj and a new commitment value cj;
• and
• collecting commitment values xj to obtain a commitment value tuple {tilde over (x)}, and signing each of commitment values cj by using a private key ski to obtain the commitment value tuple {tilde over (c)}.
