Li Feng, Ming Qiu Zhou · Jisuanji gongcheng · 2012
Simple Object Access Protocol(SOAP) has security loophole if Time Stamp issuing Authority(TSA) frauds.In order to solve the problem,this paper proposes a Time stamp Protocol of SOAP based on Secondary digital signature(TPSS),which can regulate TSA’s behavior.It requires TSA to create undeniable evidence when issuing time stamp.Necessarily,other entities can verify the authenticity of timestamp.The protocol is adopted in Hulft 7 system,and the results show that the protocol can regulate TSA’s behavior and sender’s action effectively.And a more secure and more stable mechanism for network transporting can be established by the protocol.
