ABSTRACT:
A voting method includes receiving identity-based information, vote data and a passphrase for a voter, encrypting the vote data using a symmetric key, generating second identity-based information for the voter, and generating an identity-based public key using at least the second identity-based information and a voting system parameter. The symmetric key is encrypted using the identity-based public key and an identity-based asymmetric encryption algorithm. The encrypted symmetric key may be decrypted using a private key corresponding to the identity-based public key and an identity-based asymmetric decryption algorithm, wherein the private key is generated from at least the identity-based public key and a secret master key. The voter is provided with information that includes at least the encrypted vote data and the encrypted symmetric key, and the system retains anonymous identity information, encrypted vote data and the encrypted symmetric key as a paper audit trail.
