代理签字算法在智能卡认证环境中的应用
Application of Proxy Signature to Smart Card Authentication
-
摘要: 智能卡可作为理想的密钥存储介质,但由于资源有限,在其内部做公钥运算效率较低。为解决这个问 题,结合智能卡的特点,给出了一个基于代理签字算法的安全解决方案。实验表明,与其它方案相比具有高效的 特点,同时又能保证卡内密钥信息的安全。Abstract: Smart cards are ideal key storage devices, but their public key operations are inefficient because of their limited resources. To solve this problem, a scheme based on proxy signature is proposed according to the characteristics of smart cards. The experiment results show that the proposed scheme has higher efficiency than other ones in literature while guaranteeing the safety of the key on a smart card.
