  • Pin Tumbler Lock: A Shift based Encryption Mechanism for Racetrack Memory
    21st Asia and South Pacific Design Automation Conference (ASP-DAC), 2016
    Co-Authors: Zhang Hongbin, Zhang Chao, Zhang Xian, Sun Guangyu, Shu Jiwu
    Abstract:

    As various non-volatile memory (NVM) technologies have been adopted in different levels of memory hierarchy, the security issue of protecting information retained in NVM after power-off has become a new challenge, which results in extensive research on data encryption for NVM. Previous encryption approaches, however, have some limitations, such as high design complexity and non-trivial timing and energy overhead. Recently, an emerging NVM called racetrack memory (RM) has been widely investigated because of its advantages of ultra-high storage density and fast read/write speed. Besides these well-known advantages, we observe that the tape-like structure of RM cell and its unique shift operation can also be leveraged to facilitate NVM data encryption. Base on this observation, we propose an efficient shift based mechanism, named Pin Tumbler Lock (PTL), which completes encryption and decryption by shifting racetracks in several nanoseconds. Experimental results demonstrate that our design can achieve the same security strength of AES-128 with 3.1% performance overhead and 3.7% energy overhead and 1.56% storage cost and 1.6% area cost.CPCI-S(ISTP)zhanghb10@mails.tsinghua.edu.cn; zhang.chao@pku.edu.cn; zhang.xian@pku.edu.cn; gsun@pku.edu.cn; shujw@tsinghua.edu.cn354-35

  • through liquid democracy to sustainable non bureaucratic government harnessing the power of icts for a novel form of digital government
    2014
    Co-Authors: Alois Paulin
    Abstract:

    The paper summarizes the concept of Self-Service Government (ss-Gov) as presented earlier and explores how the principles of Liquid Democracy (LD) can be applied in ss-Gov for collaborative decision making. A thorough insight into the history of LD is provided and its recent developments are summarized. By combining ss-Gov and LD, the concept of Sustainable, Non-Bureaucratic Government (SNBG) is developed as a novel, blank-slate approach to government of eligibilities within- and towards governmental systems. It is argued that such entanglement of LD with ss-Gov results in a closed-circuit system that can provide end-to-end self-management of jural relations. Thus, it is argued, SNBG is a vision concept capable to enable morphable self-managed government which requires virtually no mediatory human agents for government. The feasibility of such approach is discussed based on a Gedankenexperiment featuring a modern parliamentary decision-making process. recent study (Paulin 2013) explored the computability of jural eligibilities by means of modern ICTs as a method for enabling what is named there Self-Service Government (ss-Gov). Ss- Gov is a model for governing a society in which a dedicated public administration system (a bureaucracy ) is not required for asserting a subject's (e.g. citizen's) jural eligibilities in a particular context, but rather the eligibilities can be calculated by means of relational algebra based on raw data about the subject's jural facts. This raw data, which serves as a basis of a subject's jural eligibilities, is read and written by active and passive jural subjects, who again do have the calculated eligibility to consume, and provide, respectively, this data. Thus, in theory, a closed circuit is established in which subjects of various jural statuses interact with a relational system of jural data, which through self-service manipulation of the raw data stored within enables transformation of jural eligibilities of subjects in juropolitical societies. This approach to the technical determination / calculation of jural eligibilities in a juropolitical society was named (ibid.) Constellation-Based Reasoning (CBR). The methodology on which CBR is based can be compared to " a key opening a Pin-Tumbler Lock, where the key due to its specific shape moves the pins into the right constellation, which allows the Lock to be opened " (ibid., p.1775). The Lock , then, defines the constellation and definition of the required data (defined as a relational set), which must be satisfied by the key , i.e. the data of a stakeholder and/or context in a situation, to unLock a particular eligibility in a given context. Thus, ss-Gov enables a new model of government in which eligibilities (e.g. rights) are not obtained in form of credentials from state authorities through administrative proceedings, but are rather determined by means of CBR. The mathematical basis for the determination of eligibilities enables homogeneous, standardizable technical storage, rule-based generation and access to the raw jural data, and hence its sustainable storage as structured data in computerized systems.
