Several solutions have been investigated, using different computing precision and various implementation of arithmetic operations. The results of the second level NIST tests for randomness of the proposed pseudo-random bit generators (PRBGs) are presented, that proved good cryptographic properties of the presented PRBGs. The generators described in this paper can be used for key generation in stream ciphers in secure, real-time transmission of digital signals, including audio-video applications.","PeriodicalId":231389,"journal":{"name":"14th IEEE International Symposium on Design and Diagnostics of Electronic Circuits and Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115764081","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, such a flexible communication solution is presented, applicable to all useful FFT processor lengths: 2n (n=6, 7…13) and implemented on a flexible platform: Field Programmable Gate Array (FPGA). The solution is optimized ensuring an efficient implementation with respect to resource usage whilst ensuring that the solution meets the throughput requirements of the individual standards. The key features of the efficient design include: a conflict free in-place memory replacement scheme for intermediate data storage; a dynamic address generator scheme and the CORDIC (CO-ordinate Rotational Digital Computer) technique for twiddle factor multiplication.","PeriodicalId":231389,"journal":{"name":"14th IEEE International Symposium on Design and Diagnostics of Electronic Circuits and Systems","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115430980","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}

We have developed a technique to search for the best system-affordable cryptographic protection for the messages transmitted over the internal communication bus. Towards this, we formulate the optimization technique in Constraint Logic Programming (CLP), which returns optimal results. However, CLP executions are computationally expensive and hence, we propose an efficient heuristic as an alternative. Extensive experiments demonstrate the efficiency of the proposed heuristic approach.","PeriodicalId":231389,"journal":{"name":"14th IEEE International Symposium on Design and Diagnostics of Electronic Circuits and Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121128291","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, we focus on the verification of bus bridges which are used in many hardware systems to connect two buses running different protocols. We developed an approach to assist the automatic generation of properties from the protocol specification for the formal verification of bus bridges. The technical contribution is that the final set of the verification suite is functionally complete in respect to the underlying verification tool which shows the absence of any verification holes. The approach uses an abstract model of bus bridges in terms of state machines which enables a generic work flow. In experimental evaluations we applied the approach to bus bridges based on the OCP/IP protocol family.","PeriodicalId":231389,"journal":{"name":"14th IEEE International Symposium on Design and Diagnostics of Electronic Circuits and Systems","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121225869","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}

These experiments were conducted using a reconfigurable polymorphic chip REPOMO32 which is configured (in addition to the configuration bit stream) using the level of power supply voltage (Vdd). Experiments show that polymorphic gates in the chip can be easily involved (in terms of functionality) not only by Vdd, but also by temperature. Because experiments also prove that the physical design of the REPOMO32 chip is robust enough to keep the functionality of all circuitry of the REPOMO32 and its dynamic parameters are stable enough under wide range of operating temperature, the chip can also be used for future designs of digital polymorphic circuits controlled by temperature.","PeriodicalId":231389,"journal":{"name":"14th IEEE International Symposium on Design and Diagnostics of Electronic Circuits and Systems","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127845251","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}
