基于矢量空间秘密共享的阈下信道

Subliminal channel based on vector space secret sharing

通过引入矢量空间秘密共享技术和指定接受者签名加密技术,提出一种新的阈下信道方案,并对该方案进行了安全性分析。在该方案中,任何人都可以对签名进行验证,而只有授权者子集才能提取出阈下信息,阈下信息发送者不需要与接受者的共享私钥,也不需要为接受者生成提取阈下信息的密钥对。

A new subliminal channel is proposed ignated based on vector space secret sharing scheme and desverifier signature encryption scheme. The security of this scheme is analyzed. The receiver can verify the validity of the signature but only the an authorized subset of participants can recover the subliminal message. The sender needs not to generate key pairs for the participants. The sender and the participants need not share their private keys.
