Protection of design IP is a matter of prime concern today. We propose a scheme SECURE_IP, which tackles the problem from an entirely new viewpoint. It relies on the application of cryptographic principles and the watermarking techniques to provide both direct and indirect IP protection in VLSI physical design. It makes unauthorized disclosure of a valuable design infeasible during its transmission, and can easily detect any alteration of the design file during transmission. The proposed scheme ensures authentication of the original designer as well as non-repudiation between the designer (seller) and the buyer. Illegal reselling can be efficiently detected by the proposed scheme. The algorithm SECURE_IP is tested on random and MCNC benchmark instances, and the experimental results are quite encouraging","PeriodicalId":308247,"journal":{"name":"2007 International Conference on Computing: Theory and Applications (ICCTA'07)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121143688","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}

Architecturally, it is a pipeline of four memory stages of which the first one is itself a pipelined version of a content-to-address-memory (CTAM) while the other three are traditional address-to-content memories (ATCM), namely, RAMs. The PMLeD is potentially capable of providing millions of word-by-word translations per second between an arbitrarily large number of languages but requires a highly expensive fully parallel design of the pipelined CTAM (PCTAM) stages for achieving this high throughput rate. The present design, which has been implemented and tested in the laboratory, has studied a cost-performance trade-off by designing each stage in the PCTAM with a byte-serial approach and implementing it employing a low-cost 8-bit microcontroller. The design has achieved a hefty reduction in cost and complexity at a considerable sacrifice in the throughput rate and marks a novel, simple and low-cost practical design approach to a pipelined associative memory","PeriodicalId":308247,"journal":{"name":"2007 International Conference on Computing: Theory and Applications (ICCTA'07)","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121618327","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}

A new fuzzy cluster validity index, FSym-index, which is based on the newly developed point symmetry based distance is also proposed here. FSym-index provides a measure of goodness of clustering on different fuzzy partitions of a data set. Maximum value of FSym-index corresponds to the proper clustering present in a data set. The flexibility of fuzzy-VGAPS is utilized in conjunction with the fuzzy FSym-index to determine the number of clusters present in a data set as well as a good fuzzy partition of the data. The results of the fuzzy VGAPS are compared with those obtained by fuzzy version of variable string length genetic clustering technique (fuzzy-VGA) optimizing XB-index.

This resultant feature vector is used to train the multilayer back propagation network. The network is tested with the unknown samples. The outcome of multi-layer back propagation network is verified with medical experts and this confirms classification efficiency of 90.47%, 86.66%, and 85.71% for the classes considered respectively.
