Shen Ping · Jisuanji gongcheng yu sheji · 2010
In order to better play at the role of privacy protection of DAA protocol and improve the safety of the protocol-self,Firstly,the performance and the security of DAA in existence are analyzed,the optimization strategies to meet the safety and property of DAA are listed.Secondly,some potential security problems are analyzed,such RSA security problem,malicious issuer problem,rudolph attack,cross-domain authentication problem and so on,especially some mutual problem is pointed out-Just proved in random oracle mode.Finally,some specific methods and skills required to solve the above problems are pointed out which are used to build new DAA program and implement the security proof of new program in the standard model.
