Attribute-Based Signcryption Scheme on Vector Space
Yi Zhuang · Dianzi xuebao · 2013
This paper proposed attribute-based signeryption(ABSC) scheme.By introducing the idea of signeryption,attribute-based eneryption(ABE) was improved to attribute-based signeryption,which can complete eneryption and signature with the cost of once encryption,or to complete the mutual authention and signature with the cost of once eneryption,or to complete the mutual authentication with the cost of once signature.Through constructing the access structure on vector space,ABSC breaks the threshold limit.And based on the discrete logarithm problem,the verification algorithm was designed so that the deceptions from the internal participants can be found.
