Provable Security is a formal method for proving the security of cryptographic schemes, in which the difficulty of breaking a particular scheme is formally related to that of solving a widely believed computational hard problem. Provable security has already become an important theme of theoretical researches in modern cryptography. This dissertation investigates the provable security of public-key encryptions and hybrid encryptions of asymmetric and symmetric encryptions. This includes the various formal security notions and the constructions can be proved to achieve them. Among the constructions, hybrid encryptions are themselves an important way to obtain public-key encryption schemes with chosen ciphertext security. The main results are as follows:(1) The one-wayness of the trapdoor one-way function in NTRU depends on the randomness of the session key, which is different from previous ones. Based on this observation, a new kind of trapdoor one-way function, trapdoor one-way functions with an auxiliary random variable is proposed.

This makes the definition even not equivalent to the indistinguishability, which contradicts with what has been widely acknowledged.(3) One-time and multi-message hybrid encryptions is separated, especially the security definitions for them. For the most direct paradigm of hybrid encryption PKE+SKE, the IND-CCA_I security when it is a one-time one and the IND-CCA5 security when it is a multi-message one are proved respectively. For both of them, the necessity of the security requirement for PKE and SKE is discussed.(4) For the KEM+SKE multi-message hybrid paradigm, i.e.

For the unsuitabihty of the Tag-KEM/DEM to be used as multi-message hybrid encryptions, a new hybrid paradigm, KEM/Tag-DEM, is proposed with its security proof. For the corresponding multi-message hybrid paradigm, KEM/Tag-SKE, security is also proved. Two constructions for IND-CCA secure Tag-DEMs are proposed with the security proof.

This invention provides a method for transferring third party landing based on IP network including: a door network station carries a ciphered KEY generated randomly by a service server to send a link request to a third party network station so as to avoid transmission of user ciphered codes and ensure absolute security of user codes, besides, since the third party network station calls back the Web server by copying the ciphered KEY to verify the cryptographic key so as to secure the absolute safety of shaking hands, since the door network station does not transfer user ciphered codes with the third party network station, which is not necessary to synchronize with the door station about codes, thus the requirement of complicated maintenance to synchronization on ciphered codes to the third party is reduced.
本发明提供了一种基于IP网络转接第三方登陆的方法,其关键是,由门户网站携带业务服务器随机生成的加密KEY向第三方网站发送链接请求,避免了用户密码的传输,因而保证了用户密码的绝对安全性。再有,由于第三方网站通过复制加密KEY回调Web服务器,由Web服务器进行密钥验证,因而又保证了握手的绝对安全性。应用本发明,由于门户网站与第三方网站之间不传递用户密码,使得第三方网站无需与门户网站进行密码同步等机制的处理,在大大提高安全性的同时,降低了对第三方网站对于密码同步机制等复杂维护的要求。
