This paper reports the experimental evaluation of a complete BBICS architecture, designed to simultaneously monitor PMOS and NMOS transistors, under Photoelectric Laser Stimulation (PLS). The obtained results are the first experimental proof of the efficiency of BBICS in laser fault injection detection attempts. Furthermore, this paper highlights the importance of BBICS tapping in a sensitive area (logical gates) for improved laser detection. It studies the performances of this BBICS architecture and suggests modifications for its future implementation.","PeriodicalId":413023,"journal":{"name":"2015 IEEE 21st International On-Line Testing Symposium (IOLTS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131184367","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 arbiter PUF is a typical kind of strong PUF. However, due to its deterministic logic, attackers can use modeling techniques to break it in short time. Therefore, this paper proposes an Obfuscation logic based PUF (OPUF) design. A Boolean obfuscation module is proposed to obfuscate the logic which is employed to select the path segments in the arbiter PUF. In this way, the nondeterminacy of PUF is improved, and the computation complexities of modeling attacks are significantly increased, making the OPUF much safer against modeling attack. Both the theoretical analysis and the experimental results show the proposed OPUF design has good stability and randomness.","PeriodicalId":413023,"journal":{"name":"2015 IEEE 21st International On-Line Testing Symposium (IOLTS)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129165319","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}

Wunderlich","doi":"10.1109/IOLTS.2015.7229839","DOIUrl":"https://doi.org/10.1109/IOLTS.2015.7229839","url":null,"abstract":"Linear system solvers are key components of many scientific applications and they can benefit significantly from modern heterogeneous computer architectures. However, such nano-scaled CMOS devices face an increasing number of reliability threats, which make the integration of fault tolerance mandatory. The preconditioned conjugate gradient method (PCG) is a very popular solver since it typically finds solutions faster than direct methods, and it is less vulnerable to transient effects. However, as latest research shows, the vulnerability is still considerable. Even single errors caused, for instance, by marginal hardware, harsh operating conditions or particle radiation can increase execution times considerably or corrupt solutions without indication. In this work, a novel and highly efficient fault-tolerant PCG method is presented. The method applies only two inner products to reliably detect errors. In case of errors, the method automatically selects between roll-back and efficient on-line correction. This significantly reduces the error detection overhead and expensive re-computations.","PeriodicalId":413023,"journal":{"name":"2015 IEEE 21st International On-Line Testing Symposium (IOLTS)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132874872","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}
