常數(shù)長度密文的模糊屬性基簽密方案
發(fā)布時間:2019-06-11 19:57
【摘要】:針對目前模糊屬性基簽密方案密文長度隨屬性個數(shù)線性增加的問題,提出了一個密文長度為常數(shù)的模糊屬性基簽密方案。該方案利用拉格朗日插值公式和雙線性對進(jìn)行構(gòu)建。簽密者可將一段消息簽密后發(fā)送給具有指定屬性集的多個用戶,同時保證消息的機密性、不可偽造性等安全屬性。和現(xiàn)有同類模糊屬性基方案相比,該方案需要的運算量最少,并同時支持常數(shù)長度的密文,具有更好的效率。
[Abstract]:In view of the problem that the length of the cipher text is linearly increased with the number of the attribute, a fuzzy attribute-based signature scheme with the length of the cipher text is proposed. The scheme is constructed by the Lagrange interpolation formula and the bilinear pair. The signaler can send a piece of message to a plurality of users with a specified attribute set, and simultaneously ensure the confidentiality and the non-forge property of the message. Compared with the prior similar fuzzy attribute-based scheme, the scheme required by the scheme is the least, and the cipher text with constant length is supported at the same time, and the scheme has better efficiency.
