Patent Searching and Data


Title:
公正ブラインド署名を使用する電子投票プロセス
Document Type and Number:
Japanese Patent JP4727651
Kind Code:
B2
Abstract:
In an electronic voting process, a voter (Vi) encrypts his vote (vi) according to the encryption scheme (ETM) of a tallier mix-net (50) used to tally up the votes cast. The voter (Vi) obtains on his encrypted vote, (xi), from an admin server module (20), a digital signature according to a fair blind signature scheme (FBSS). The encrypted vote (xi) is encrypted a second time, together with the unblinded digital signature (yi) thereof by the admin server, using the encryption scheme (EM) of a randomizing mix-net (40), to yield an output (ci), and the voter uses his own signature scheme (Si) to sign this, giving ( sigma i). The voter sends an ID code and data including (ci, sigma i) to a bulletin board server (30). Discrepancies in this vote data can be detected and their origin traced by prompting the randomizing mix-net servers (40) to provide proofs of correctness, and using the signature-tracing mechanism of FBSS.
