A New Approach to Determining the Time-Stamping Counter's..

چکیده
Due to its moderate overhead and small quantization error, the time-stamping counter is currently the most precise time-measuring mechanism on Intel 80X86-based Platform. On the Pentium processors, we can simply use a conventional null benchmark to determine the time-stamping counter’s overhead accurately. Similarly, on the Pentium Pro processors, Intel also recommends the same method for measuring this overhead. However, since the influence of the measured operation is neglected, we find this method becomes inaccurate on Pentium Pro. Therefore, in this paper, we propose a new method for determining the overhead of Pentium Pro‘s time-stamping counter. Furthermore, we also provide some empirical results to confirm the feasibility of our idea.

Optimally Efficient Accountable Time-Stamping
Efficient secure time-stamping schemes employ a 2-level approach in which the time-stamping service operates in rounds. We say that a time-stamping service is accountable if if it makes the TSA and other authorities accountable for their actions by enabling a principal to detect and later prove to a judge any frauds, including attempts to reorder time-stamps from the same round. We investigate ...

electronic document existed at a certain point in time and that it has not been modified since then. Different time-stamping schemes have already been proposed. Most of them use the concept of trusted Time-Stamping Authority (TSA). A TSA is in charge of time-stamping documents and delivering a timestamping certificate for each time-stamped document. The purpose of this paper is to propose a new...

Without addressing and solving them, any advantage of the linkage-based protocols over the hash-and-sign tim...
متن کاملA New Nonlinear Multi-objective Redundancy Allocation Model with the Choice of Redundancy Strategy Solved by the Compromise Programming Approach
One of the primary concerns in any system design problem is to prepare a highly reliable system with minimum cost. One way to increase the reliability of systems is to use redundancy in different forms such as active or standby. In this paper, a new nonlinear multi- objective integer programming model with the choice of redundancy strategy and component type is developed where standby strategy ...
متن کاملInvestigation on Forming of Titanium Bipolar Plates Using Micro-stamping Process
Micro-stamping process is one of the most cost-effective methods to manufacture metallic bipolar plates (BPPs). This research investigates the forming of titanium thin sheet as a potential candidate for BPPs in proton exchange membrane fuel cell (PEMFC). In this regard, the process was first simulated using finite element (FE) code Abaqus. Afterward, experimental tests were implemented and the ...
