Verification method for operation of encryption apparatus and its application to electronic voting
A verification method for encrypter operation and an electronic voting verification system using the same, which can verify the operation of the encrypter without having to execute corresponding decryption. In the verification method, the encrypter creates a plurality of ciphertexts corresponding to the plain text and presenting the ciphertexts to a user. The user selects one of the ciphertexts, the encrypter dispenses a certificate where information used by the encrypter during encryption is recorded, in response to the ciphertexts which are not selected by the user; and the user creates a ciphertext in person and verifies whether or not the user-created ciphertext is identical with the user-selected ciphertext. Then, the user can verify the encryption results inside and outside a polling booth.
