这次演讲概述了最近开发的分组密码加密模式，称为CENC。CENC具有以下优点：(1)超越寿命界安全性；(2)基于标准PRP假设的安全性证明；(3)高效；(4)单密钥；(5)完全并行化；(6)允许密钥流的预计算；(7)允许随机访问。然后，我们讨论了它的安全界的紧性，并部分地回答了在FSE 2006上提出的公开问题。
This talk presents an overview of recently developed encryption mode for blockciphers, called CENC. CENC has the following advantages: (1) beyond the birthday bound security, (2) security proofs with the standard PRP assumption, (3) highly efficient, (4) single blockcipher key, (5) fully parallelizable, (6) allows precomputation of keystream, and (7) allows random access. Then we discuss the tightness of its security bound, and give a partial answer to the open problem posed at FSE 2006.
