A Proxy Key Confusion Electronic Voting System and Method Against Malicious Attacks

Abstract

The present invention discloses an anti-malicious attack proxy secret key mixing-based electronic voting system and method. The system comprises a proxy voting program module and a voting information verification module. The proxy voting program module comprises a pre-processed parameter generation unit, a signature private key encryption unit, a mixing program unit, and a voting information output unit. The information verification module comprises a voting result receiving unit, a decoding unit, and a voting information verification unit. The system has the characteristics of low complexity, high security, and simplicity in verification. The system and method are applicable to an electronic voting server that is likely to be attacked maliciously. Even if the voting server suffers malicious attack, whether invalid votes exist can be found (each voter signs on his own vote, and a notary can find out ballot rigging), and a hacker cannot acquire signature private key information of the voter from the attacked electronic voting server.

Description

technical field [0001] The present invention relates to the field of data security, in particular to an electronic voting server. Taking electronic voting as an object, combining cryptography technology with cloud computing and cloud storage, the electronic voting server is used to sign electronic voting and prevent the electronic voting server from being maliciously attacked. Scenarios in which the private key is compromised. Background technique [0002] With the rapid development of cloud computing and storage technologies, major IT companies have successively launched their own cloud servers, and more and more users have begun to use these cloud servers for outsourced computing or storage. Electronic voting has become one of the more and more popular services used in daily life. The use of electronic voting has developed from politics, business, and science to the general public. It is also important to ensure the validity and legitimacy of electronic voting. become mor...

Problems solved by technology

There are many problems in this kind of scheme: (1) Voters send voting information directly to the voting server. If the voting server is attacked maliciously, the number of votes may be modified, which directly affects the fairness of voting; (2) ) Sign everyone's vote on the server to avoid vote swiping. Although this method can avoid swiping votes, if the server is attacked maliciously, the signature private key of the voting participant will be leaked
