第7章防护策略、缓解手段和对抗措施

(1)要求软件厂商提供带数字签名的代码.尽管带数字签名的代码也并不总是安全,但一般来讲,它比不带数字签名的代码要安全许多.代码数字签名与代码作者之间建立了紧密联系,便于识别那些被篡改、被感染的文件以及其他遭破坏的文件.1H09,被发现的独立威胁文件中大约有97%是没有签名的.除了Win32/GameVance和Win32/Wintrtm种类的病毒,剩余的威胁文件中有99.9%是没有代码签名的.

防静电技术讲座19 实用静电防护工艺 第七章 静电防护的标准

我国的静电防护标准尚不完善,静电放电控制方面的国家标准尚待颁发。生产防静电器材的工厂,部分已有企业标准发布,较为完善的是浙江椒江特种塑料厂的企业标准。该厂产品通过部级鉴定,也是我国迄今为止唯一通过部级鉴定的静电器材生产厂。但多数工厂的企业标准尚待完善。国外的静电控制标准早就很完善,尤以地区标准为多。如美国的MIL—B—×××,MIL—STD—×××系列防静电标准;华盛顿特区的静电控制大纲;美国EIA-541系列标准;IEC—TC40文件,英国的BS5958防静电通用规范和日本的部分产品标准等。尤以美英标准较为完整详细。

强电线对通信线的影响和防护措施

强电线路对通信线路影响的实质,就是强电线路中的交变电流所产生交变电磁场,作用到其附近的通信线路上产生的电磁感应。通信线路因受强电线影响轻则干扰通信回路通话,严重的能毁坏机线设备,危及工作人员的生命安全。为保护通信设施和施工维护作业人员的安全,减少强电线路对通信线路的影响,必须采取有效措施,加强通信线路的防护。本文分析强电线路对通信影响和危害,提出减少强电线路对通信线路的影响措施。     

Strategies for Peace, Strategies for News Research

Despite the seeming uniformity of media presentation of news about peace, the formats of news reporting and the contest among various discourses allow for the appearance and sometimes prominence of alternative and men oppositional discourses that offer a pragmatic for social action.     

Special Section on Energy-Efficient Technologies:NoC Circuits,Architectures, and Systems

Energy consumption has been one of the major challenges and concerns for the electronic devices design, especially in high-performance multi- and many-core systems. A highly integrated many-core chip is prone to be extremely high-power consumption that exceeds the chip＇s power budget set leaded by cooling, packaging and/or the capacity of the power supply. When this situation happens, various parts of the many-core chip will have to be deliberately switched off （darkened） so that the chip is still in compliance with its power budget, which is referred as ＂dark silicon＂. Therefore, the research on energy efficient computing is a current trend and will continue to be an active area in the coming years.     

Hydrophobized Hydrogels: Construction Strategies,Properties, and Biomedical Applications

Hydrogels, as 3D networks containing huge amount of water, display similarity to soft tissues, and thus they are of wide interest in tissue engineering. Hydrogels, due to biocompatibility and porous structure, are valuable therapeutic platforms for hydrophilic drugs. Over the last decade, there has been a strong emphasis on the development of hydrogel platforms with the ability to increase the solubility of hydrophobic drugs. However, the pronounced discrepancy between the hydrophilic character of hydrogels and the hydrophobic nature of numerous pharmacologically active compounds is problematic. In recent years, different strategies are applied using special polymer constructs or composite materials exploiting the advanced scientific knowledge in the area of polymer and lipid-based nano- and microcarriers hydrophobization of the hydrogel turns out to be not only valuable in terms of achieving the ability to dissolve poorly soluble drugs in water, but also proves to be crucial in obtaining bioadhesion in wet conditions, but also, unexpected abnormal water swelling behavior, as well as in mechanical properties such as the dissipation mechanism and self-healable hydrogel properties. This review is mainly focused on recent advances in the usage of hydrophobized hydrogels in biomedical applications.

Efficient Cache Attacks on AES, and Countermeasures

We describe several software side-channel attacks based on inter-process leakage through the state of the CPU’s memory cache. This leakage reveals memory access patterns, which can be used for cryptanalysis of cryptographic primitives that employ data-dependent table lookups. The attacks allow an unprivileged process to attack other processes running in parallel on the same processor, despite partitioning methods such as memory protection, sandboxing, and virtualization. Some of our methods require only the ability to trigger services that perform encryption or MAC using the unknown key, such as encrypted disk partitions or secure network links. Moreover, we demonstrate an extremely strong type of attack, which requires knowledge of neither the specific plaintexts nor ciphertexts and works by merely monitoring the effect of the cryptographic process on the cache. We discuss in detail several attacks on AES and experimentally demonstrate their applicability to real systems, such as OpenSSL and Linux’s dm-crypt encrypted partitions (in the latter case, the full key was recovered after just 800 writes to the partition, taking 65 milliseconds). Finally, we discuss a variety of countermeasures which can be used to mitigate such attacks.
