1203 策略三十六计和算法三十六计可以为计算机专业人员在学习和系统研发工作中提供思维框架、策略辩证思路和需要的计策及实例, The thirty-six stratagems of schemes and thirty-six stratagems of al-gorithms can provide computer professionals with thinking framework, dialectical thinking and necessary stratagems and in-stances in learning and developing computer systems.
1204 更为重要的是可以进一步理解事物的哲学道理。 More importantly, they can help the computer professionals further un-derstand the philosophical principles of things.
1205 现有的可公开验证的匿名基于身份的加密(Identity-Based Encryption,IBE)机制声称解决了在静态困难性假设之上构造紧的选择密文安全的 IBE 机制的困难性问题。 How to create an identity-based encryption (IBE)scheme with tight chosen-ciphertext attacks (CCA)se-curity based on the static assumption is an open problem. A publicly verifiable anonymous IBE scheme designed in the stand-ard model claimed that the CCA security of proposed scheme was proved based on the classic static assumption.
1206 然而,本文发现,由于该机制的密文不具备防扩展性,使得任何敌手可基于已知的有效密文生成任意消息的合法加密密文,导致该机制无法满足其所声称的选择密文安全性。 However, in this paper, we demonstrate that the previous IBE scheme cannot achieve the claimed CCA security because the ciphertext wasextensile. In other words, a valid encrypted ciphertext can be forged by any adversary from a known ciphertext.
1207 我们根据不同的密文相等判定条件分别提出两种方法对原始方案的安全性进行了分析,同时在分析基础上指出原始安全性证明过程中所存在的不足。 To analyze the security of the previous IBE scheme, two methods are proposed based on the criterion of ciphertext equality. Additional-ly, based on the analysis of the previous IBE scheme, we point out the shortcomings of the original security proof.
1208 GPS (Global Positioning System)在新一代卫星载荷中采用了大量新技术, GPS III (Global Positioning System)satellites have adopted a large number of new technologies in pay-load.
1209 首颗卫星成功发射后,官方尚未系统公布各导航信号的调制方式、复用方法等关键信息,因而其在轨测试阶段的空间信号质量评估具有重要的意义。 After the successful launch of the first satellite, the official has not yet published effective information such as the mod-ulation method of each navigation signal and multiplexing method. Therefore, it is meaningful to evaluate the signal-in-spacequality.
