Proposed Secured Remote E-Voting Model based on Blind Signature
We proposed a secured e-voting system model by using blind signature. Our proposed model meets all security requirements which are: (authentication, privacy, integrity, non repetition). Our proposed model depends on these main entities that are involved within the voting processes (voter registration, voting, counting, audit), and these entities are: certificate authority, ministry of interior, voter, high committee of elections (investigator), and counter. The voter can vote from any remote with secured data transfer (ballot) by using the blind signature to blinded ballot and then sign it. When it is sent to the high committee of elections (investigator) for checking the voter eligibility, there is an encrypting random value (r) that is attached with the blind ballot, using for removing blind the ballot which is encrypted by counter’s public key. The high committee of elections checks the signature of voter and checks that if he is an eligible voter or not. Then removes the voter’s digital signature and puts his digital signature and then sends it to the counter party. The counter party checks the signature of high committee of election and extracts the random value (r) by decrypting with his private key and removing the blind ballot and counts the vote.
