基于身份加密的可变形加密方案构造
Construction of anamorphic encryption scheme based on identity-based encryption
摘要
Abstract
The confidentiality of data communication heavily relies on the security of encryption keys.Traditional communication security is primarily based on the assumptions of sender freedom and receiver privacy.However,in certain coercive environments,these assumptions may be compromised,leading to the disclosure of message content or key leakage.To address the issue of the receiver privacy assumption being violated,this paper proposes an anamorphic encryption scheme based on IBE-to-CCA conversion.By introducing a pseudorandom function,this scheme upgrades an identity-based encryption scheme into an anamorphic encryption scheme,significantly enhancing its security in the event of key leakage.关键词
