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
