摘要:

针对异构云部署复杂、计算量大、频繁信息交互等问题,提出了认证代理和服务代理两种异构云服务模式,设计了异构云中具有较低握手次数的代理签名方案,从而提高了认证执行效率。 此外,该方案能够有效防止恶意节点的重放攻击、伪造攻击和中间人攻击等。

关键词: 异构云, 认证协议, 代理

Abstract:

Considering the comp1exity of dep1oying network nodes, 1arge amount of ca1cu1ation and frequent mutua1 messages for heterogeneous c1oud, two service patterns, i.e.authentication agent and service agent were proposed, A1so, the proxy digita1 signature schemes with 1ower handshaking numbers were devised and the efficiency of authentication imp1ementation was improved.In addition, the scheme can effective1y guard against the rep1ay attack, the impersonation attack and the man-in-the-midd1e attack of the ma1icious nodes,and so on.

Key words: heterogeneous c1oud, authentication protoco1, agent
