In this paper, the authors propose a new secure e-voting protocol based on public-key encryption cryptosystem. This protocol is summarized in three processes: firstly, access control process which involves the identification and authentication phases for the applied citizens. Secondly, the voting process which will be done by ciphering the voter information using public-key encryption cryptosystem (RSA), to be submitted over an insecure network to the specified government election server. Finally, the election server administrator will sort the final result by deciphering the received encrypted information using RSA private key.
