%A MA Rong,CAO Zhenfu%T An Efficient and Full Secure IdentityBased Encryption Scheme %0 Journal Article %D 2010 %J Journal of Shanghai Jiao Tong University %R %P 389-0392 %V 44 %N 03 %U {https://xuebao.sjtu.edu.cn/CN/abstract/article_39277.shtml} %8 2010-03-30 %X This paper presented an efficient and secure identitybased encryption scheme. Compared to the previous scheme, it has the advantage of security or efficiency. This new scheme can achieve adaptive CCA2security under BDH assumption with tight reduction. The construction was made by use of the “Twin DiffieHellman” technique proposed by Cash et al, only requiring one pairing computation during the encryption procedure.
