| 1 | An improved attack on clock-controlled shift registers based on hardware implementation显示文摘We cryptanalyze a type of stream generator with three linear-feedback shift registers that are mutually clocked in a stop/go manner and have the property of sequences of state space convergence.By guessing the clock-controlled sequence and employing a backtracking search,we propose an algorithm attack on the type of stream generator based on hardware implementation.In particular,the time complexity of the algorithm attacking the encryption algorithm A5/1 is 243.869 clock periods.With our hardware architecture,we investigate the implementation of the algorithm on feld programmable gate array and application-specifc integrated circuit for an attack on A5/1.As a result,we can retrieve the initial states of A5/1’s registers in 2 s on average without pre-computation if we have 64 known key-stream bits. | LI Lei LIU XiangHui WANG Zheng LI FengHua | 2013 | Science China(Information Sciences)2013，56，11： | 2 |
| 2 | A framework of physical layer technique assisted authentication for vehicular communication networks显示文摘In this paper, we introduce a message physical layer assisted message authentication (PAA) framework under public key infrastructure (PKI) in vehicular communication networks. The proposed framework takes advantage of temporal and spatial uniqueness in physical layer channel responses for each transmission pair, in which a trust between two vehicles can be maintained by comparing the current estimated channel response and the previous estimated channel response. We will show that the proposed message authentication framework can achieve high efficiency and minimal authentication delay without compromising the security requirements, which is further verified through both analysis and simulation. | WEN Hong HO PinHan GONG Guang | 2010 | Science China(Information Sciences)2010，53，10： | 2 |
| 3 | Using IND-CVA for constructing secure communication显示文摘Within the framework of UC (universally composable) security, a general method is presented to construct a secure channel protocol with using IND-CVA (indistinguishability of encryption scheme under ciphertext verification attacks). A channel protocol with using the method first invokes an ideal keyexchange protocol to get a session key, and then computes the messages with an authenticated encryption scheme. The paper shows that a channel protocol is UC secure if and only if the underlying authenticated encryption scheme is both IND-CVA secure and INT-PTXT secure. The condition about secure channel protocol in this paper is much weaker than IND-CCA secure and INT-CTXT secure. The IND-CVA can be presented for describing the privacy requirements of secure channels in detail. Moreover, the method for designing secure channel protocol in the paper reduces the UC security of secure channels, which are measured by action-simulation in the UC security framework, to the security of authenticated encryption schemes, which are measured semantically. | HU ZhenYu JIANG JianChun SUN FuChun | 2009 | Science in China(Series F)2009，52，10： | 0 |
| 4 | 利用IND-CVA实现安全信道显示文摘在UC安全框架下,文中提出了一个通用的安全信道协议构造方法.按该方法得到的信道协议首先调用一个理想的密钥交换协议以取得会话密钥,然后再调用一个认证加密方案对要传送的消息进行认证加密处理.其结果是,该安全信道是UC安全的充分必要条件是,其中的认证加密方案同时是IND-CVA和INT-PTXT安全的.这一结论比IND-CCA安全和INT-CTXT安全要弱得多,显示出IND-CVA在刻画安全信道的保密安全性方面的准确性.另外,文中提出的安全信道的构造方法也实现了从安全信道的UC安全性到认证加密方案的保密性和完整性的转换,为安全信道的设计和分析提供了有力的工具. | 胡振宇 蒋建春 孙富春 | 2009 | 中国科学(F辑:信息科学)2009，39，12： | 0 |
