Electronic Consumption Scheme Based on Linkable Ring Signature
摘要
Abstract
In existed electronic consumption system, multi-consumption often occurs and causes low efficiency even cash disorder. For tackling this trouble,this paper proposes a new efficient and safe electronic consumption scheme. The scheme is based on bilinear pairings and linkable ring signature. Linkable ring signature has the efficiency and the security of ring signature. The scheme can check whether the signature is correct or not. It can detect the same user uses limited amount of cash repeatedly,by the three stages of designing,consuming and saving,connects the transaction of consumers, businesses and banks each other, and makes electronic consumption go on. The scheme can preserve the user ’ s anonymity,prevent multiple consuming, and satisfy the basic requirement of electronic consuming. Analysis and proof show that the scheme is more feasible and efficient than the scheme proposed by Liu,etc. ( Wuhan University Journal of Natural Sciences,2013,No. 2).关键词
