A new Transient-Steady Effect attack on block ciphers called TSE attack is presented in this paper. The concept of transient-steady effect denotes the phenomenon that the output of a combinational circuit keeps a temporal value for a while before it finally switches to the correct value. Unlike most existing fault attacks, our attack does not need a large amount of encryptions to build a statis...

Recently different approaches have been developed in the field of sensor fault diagnostics based on Auto-Associative Neural Network (AANN). In this paper we present a novel algorithm called Self reconstructing Auto-Associative Neural Network (S-AANN) which is able to detect and isolate single faulty sensor via reconstruction. We have also extended the algorithm to be applicable in multiple faul...

Many web cache systems and policies have been proposed. These studies, however, consider large sized objects less useful than small sized objects for the performance and evict them as soon as possible. Even if this approach increases the hit rate, the byte hit rate decreases and more bandwidth is used to obtain large sized objects. This paper suggests the web cache system which uses the client-...

In data deduplication systems, chunking has a significant impact on the ratio and throughput. Existing Content-Defined Chunking (CDC) approaches exploit sliding window to calculate rolling hashes of input stream byte-by-byte, then determine chunk cut-points if hash satisfies given cut-condition...

Multistage Interconnection Networks (MIN) with multiple outlets are networks which can support higher bandwidth than those of nonblocking networks by passing multiple packets to the same destination. Fault recovery mechanisms are proposed for two of such networks (TBSF/PBSF) with the best use of their inherent fault tolerant capability. With these mechanisms, on-the-fly fault recovery is possib...

Distributed shared memory (DSM) system provides simplicity of shared-memory programming on cluster of computers. Compared to hardware approach, software DSM is a relatively low-cost, low-risk entry into the concurrent computing arena. However, fault detection becomes essential when software DSM is used to execute long-running applications. When one of the remote processor crashes or the process...

Multiple fault diagnosis is a difficult problem for dynamic systems, and, as a result, most multiple fault diagnosis approaches are restricted to static systems, and most dynamic system diagnosis approaches make the single fault assumption. Within the framework of consistency-based diagnosis, the challenge is to generate conflicts from dynamic signals. For multiple faults, this becomes difficul...

The Ethernet encapsulation (framing) overhead is a result of adding 8-byte frame preamble, 14-byte Ethernet header, and 4-byte FCS field to MAC Service data units (m_sdu) comprised of user’s data. Additionally, at least 12-byte minimum inter-frame gap (IFG) should be left between two adjacent frames. Thus, the absolute overhead per one frame is constant and equal to 38 bytes (see Figure 1). Thi...

CJK (Chinese, Japanese and Korean) language systems are using multi-byte coding, while encoding of existing Indian languages is based on single-byte coding scheme. Due to the special characteristics of Indian languages, it is advantageous to consider multi-byte encoding for computer processing of Indian languages. In this paper, we discuss a model of encoding and processing Indian languages in ...
