摘要
在网格安全标准中,实体间的跨域身份认证采用基于证书的公钥基础设施认证框架,证书的管理过于复杂,限制了网格规模的扩大。针对上述问题,在分析网格安全需求的基础上,引入基于身份的密码体制,提出一种跨域签密方案,以解决使用不同系统参数的虚拟组织间相互认证的问题,并对其安全性和性能进行分析。
In Grid Security Infrastructure(GSl), cross-domain authentication between entities adopts the traditional certificate-based Public Key Infrastructure(PKI) which limits grid scale since the management of certificates is too complicated. By analyzing the security demands, this paper introduces Identity-Based Cryptography(IBC) to grid and proposes a cross-domain signcryption scheme to solve the problem brought by authentication between Virtual Organizations(VO) with different system parameters. Its security and performance are analyzed.
