Non-optimistic Secure Circuit Evaluation Based on ElGamal Encryption and Its Applications Koji CHIDA Go YAMAMOTO Koutarou SUZUKI Shigenori UCHIYAMA Noburou TANIGUCHI Osamu SHIONOIRI Atsushi KANAI Publication IEICE TRANSACTIONS on Fundamentals of Electronics, Communications and Computer Sciences Vol.E90-A No.1 pp.128-138 Publication Date: 2007/01/01 Online ISSN: 1745-1337 DOI: 10.1093/ietfec/e90-a.1.128 Print ISSN: 0916-8508 Type of Manuscript: Special Section PAPER (Special Section on Cryptography and Information Security) Category: Protocols Keyword: secure circuit evaluation, multiparty protocol, ElGamal encryption, implementation, Full Text: PDF(467.6KB)>>
Summary: We propose a protocol for implementing secure circuit evaluation (SCE) based on the threshold homomorphic ElGamal encryption scheme and present the implementation results of the protocol. To the best of knowledge of the authors, the proposed protocol is more efficient in terms of computational complexity than previously reported protocols. We also introduce applications using SCE and estimate their practicality based on the implementation results. | ||||||||||
