Only one ciphertext corresponding to the message is generated regardless of the number of receivers. Thus it is practical and useful for video conferencing systems, pay-per-view channels, distance education, and so forth. In 2010, for further protecting receivers’ privacy, anonymous multi-receiver identity-based (ID-based) encryption was first discussed, and from then on, many works on the topic have been presented so far. To deal with the key escrow problem inherited from ID-based encryption (IBE), Islam et al. proposed the first anonymous multi-receiver certificateless encryption (AMRCLE) in 2014. In 2015, Hung et al. proposed a novel AMRCLE to improve the efficiency. However, we found that their security proofs are flawed, i.e., the simulation cannot be successfully performed. In this paper, we present a novel AMRCLE scheme with CCA security in confidentiality and anonymity against both Type I and Type II adversaries. Moreover, the identity of the sender of a ciphertext can be authenticated by the receiver after a successful decryption. To the best of our knowledge, the proposed scheme is the first CCA secure AMRCLE scheme, and furthermore, we also pioneer in achieving sender authentication in AMRCLE. 關聯 Journal of Information Science and Engineering, Vol.34, No.6, pp.1517-1541 資料類型 article dc.contributor 資科系 dc.creator (作者) 曾一凡 dc.creator (作者) Tseng, Yi-Fan dc.creator (作者) Fan, Chun-I dc.date (日期) 2018-11 dc.date.accessioned 2-Sep-2020 09:14:46 (UTC+8) - dc.date.available 2-Sep-2020 09:14:46 (UTC+8) - dc.date.issued (上傳時間) 2-Sep-2020 09:14:46 (UTC+8) - dc.identifier.uri (URI) http://nccur.lib.nccu.edu.tw/handle/140.119/131407 - dc.description.abstract (摘要) Multi-receiver encryption allows a sender to choose a set of authorized receivers and send them a message securely and efficiently.
