In this paper, the author proposes a robust online signature verification algorithm against attacks using the hill-climbing method. Specifically, the attack considered in this paper is a hill-climbing forged data attack. Artificial forgeries are generated by using the hill-climbing method and the forgeries are input to a target system to be attacked. In order to generate a robust algorithm, the author proposes incorporating the hill-climbing method into an online signature verification algorithm. Preliminary experiments were performed using several online signature databases. The results show that the proposed algorithm improved the performance against this kind of attack. Equal Error Rate (EER) was improved from 88.3% to 1.2% when using a private database for evaluation.","PeriodicalId":430277,"journal":{"name":"2008 IEEE/IFIP International Conference on Embedded and Ubiquitous Computing","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115810095","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our processing system includes a 16-bit processor, a cross assembler, and a cross compiler. The 16-bit processor runs in 89 MHz on the Xilinx Spartan-3A family FPGAXC3S700A using 336 out of 5888 slices (5.7%)and in 76 MHz on the Altera Cyclon III family EP3C25F324 using 569 out of 24624 logic elements (2.3%). Every instruction can be executed in only one clock cycle, that is, CPI=1. Using a cross assembler and a cross compiler that we have developed, a C-based language program can be translated into a machine language object code, which can be executed on the 16-bit processor. The source codes of our processing system are very simple and compact. The 16-bit processor is designed by Verilog~HDL using 268 lines, and the cross assembler is written in 38 lines using Perl language. The cross compiler has 23 lines of Flex grammar file for lexical analysis, and 90 lines of Bison grammar file for context analysis and code generation. Hence, our tiny processing system is portable and easy to understand and the function expansion is not difficult. Actually, the tiny processing system has been used for the embedded system course of graduate students as a course material. Further, the 16-bit processor is scalable, that is, the word size can be changed from standard 16 bits. As real-life applications, we have developed a PONG-like mini game and an RSA encryption/decryption system based on the tiny processing system. Therefore, our tiny processing system benefits computer system education and small embedded system development.","PeriodicalId":430277,"journal":{"name":"2008 IEEE/IFIP International Conference on Embedded and Ubiquitous Computing","volume":"117 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131534101","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Time-triggered CAN (TTCAN), which achieves time-triggered behavior by implementing time-division multiple access on the CAN network standard, is an option that will form the basis of a new generation of advanced safety critical distributed systems. Considering several performance metrics, such as bandwidth utilization, an optimal message schedule must be constructed for a given message set. In this paper, we analyzed differences between sets of messages and constructed system matrix that the schedule is generated based on it. Moreover, an optimization problem is how to make event-triggered messages gain the maximum transmission times by minimizing the transmission times occupied by time-triggered messages. A GA-based systematic message scheduling method is proposed to optimize the scheduling table. We have evaluated the proposed scheduling method using experiments.","PeriodicalId":430277,"journal":{"name":"2008 IEEE/IFIP International Conference on Embedded and Ubiquitous Computing","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130930859","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

GPRS presents several essential security weaknesses which may lead to security attacks that can compromise the network operation and the data transfer. We perform a detailed threat analysis by identifying the possible attacks that may result from the GPRS security weaknesses. The analyzed threats are categorized into critical areas of GPRS security exposure and further divided into threats that compromise the availability, confidentiality, integrity, privacy, authorization and authentication of the system. Each threat is associated with a qualitative risk value that incorporates the likelihood of the attack and its potential impact on the system. The understanding gained from the analysis is used to classify the threats in low and high risk threats and define the specific areas of GPRS that require additional security measures.","PeriodicalId":430277,"journal":{"name":"2008 IEEE/IFIP International Conference on Embedded and Ubiquitous Computing","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125566945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of common components in the processor is the Arithmetic and Logic Unit (ALU). Usually, ALUs are designed with a combinational logic circuit containing a number of functional components for different arithmetic and logic operations. An ALU can be constructed with a tree or a chain structure. Existing approaches to reduce power often achieve power reduction at the cost of increased design complexity, thus resulting in delay and area overheads. In this paper, we present a customization approach for the chain-structure based ALU design by repositioning functional components in the chain. The approach can be easily integrated into a processor design environment to effectively reduce ALU power consumption for a given application. We have applied our approach to a set of benchmarks. Ourexperimental results show that the power savings range from 43.5% to 49.6%; on average, 46.9% of ALU power reduction can be achieved. Most importantly, this achievement is at cost of neither hardware complexity nor processor performance, and the implementation is extremely straightforward.","PeriodicalId":430277,"journal":{"name":"2008 IEEE/IFIP International Conference on Embedded and Ubiquitous Computing","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124617696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, an impact-oriented metric is proposed for the measurement of interference to network routing. As to networks with capability of multi-path routing, traffic can bypass failed links or nodes by using local redundant resources. The metric check the extent to which the extra paths have been used. During this process, both the amount and the usage probability are taken into account.","PeriodicalId":430277,"journal":{"name":"2008 IEEE/IFIP International Conference on Embedded and Ubiquitous Computing","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114727263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The second mechanism uses signature monitoring to detect errors occurring in the sequential instructions. The scheme is implemented using a watchdog processor for an VHDL model of the LEON2 processor. About 31800 simulation faults were injected into the LEON2 processor. The results show that the error detection coverage is about 99.5% with average detection latency of 7 cycles.
