基于不可区分混淆的定时释放密码方案
New timed-release encryption based on indistinguishability obfuscation
摘要
Abstract
Timed-reLease encryption(TRE) is a cryptography that studies the problem of sending information into the future,it can solve many practical problems to construct a feasible and safe TRE.This paper proposed a scheme based on the research of indistinguishability obfuscation and TRE.This scheme encapsulated the sender's encryption and receiver's decryption by a circuit and obfuscated this circuit by an indistinguishability obfuscator.It could make great use of the time of obfuscators obfuscate circuits,simplified the scheme and improved the security of this scheme.Finally,this paper proves the correctness and security of this TRE scheme.关键词
