Fuzzy attribute authentication scheme based on vector space
Yi Zhuang · Computer Engineering and Applications Journal · 2012
Attribute-based authentication schemes are mainly structed on the basis of Lagrange interpolation polynoial which is firstly used to realize distributed encryption by Shaimr.In these schemes,there is a threshold that the same attributes number of participants of authentication must be greater than or equal to it,and moreover,this threshold is unalterale during once system generation.In consideration of these facts,a new attribute-besed authentication scheme is presented which is structed on vector spase.By way of building access control structure,the new scheme can design the authentication participants'fuzzy attributes flexibly,and everyone whose attributes accord with access control structe can be certified properly.Finally through the new scheme with a slight adjustment,it also can complete fuzzy attribute signature.
