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。Considering the complexity of deploying network nodes, large amount of calculation and frequent mutual messages for heterogeneous cloud, two service patterns, i.e. authentication agent and service agent were proposed, Also, the proxy digital signature schemes with lower handshaking numbers were devised and the efficiency of authentication implementation was improved. In addition, the scheme can effectively guard against the replay attack, the impersonation attack and the man-in-the-middle attack of the malicious nodes, and so on.
