Many secure CPU architectures have been proposed, mostly focusing on single-threaded applications running on a single node. However, security for parallel and distributed computation is also needed, requiring the sharing of secret data among mutually trusting threads running in different compute nodes in an untrusted environment. We propose SDSM, a novel hardware approach for providing secure directory-based distributed shared memory. Unlike previously proposed schemes that cannot maintain reasonable performance beyond 32 cores, our approach allows secure parallel applications to scale efficiently to thousands of cores.","PeriodicalId":194799,"journal":{"name":"2016 IEEE International Symposium on Hardware Oriented Security and Trust (HOST)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127264057","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 receivers are realized by modulating the supply voltage of the chip, while at the same time detecting these changes from within the chip using a ring oscillator. The levels of the supply voltage can be determined by constantly monitoring the frequency of the ring oscillator. To prove authorship of an IP core, the verifier authenticates himself to the core over the voltage side-channel and sends commands that limit the core's functionality. By monitoring the regular outputs of the overall system, it is possible to detect illegitimately used cores after repeatedly turning them on and off. The working principle of our method is demonstrated by a case study, in which we protect several IP cores and place them on a Spartan 3 FPGA, and show the steps necessary for successful proof of ownership verification.","PeriodicalId":194799,"journal":{"name":"2016 IEEE International Symposium on Hardware Oriented Security and Trust (HOST)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126149264","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}

At runtime, Hamming distance between the codes assigned to the source and destination basic blocks are calculated and compared against the known constant, to verify the control flow. Execution is aborted if the Hamming distance comparison does not match. We implemented DSC on a cycle-accurate x86 simulator.

The GenMatch secure genome testing method utilizes Yao's Garbled Circuit (GC) protocol and creates a formulation of the matching problem in a sequential GC format. Our formulation involves private matching of genome data by the GC protocol. Our method reduces the memory footprint of the secure computation such that it can be done in a resource-constrained devices like embedded platforms, rendering the method scalable and time-efficient. Proof-of-concept evaluations are performed on the application of matching Human Leukocyte Antigen (HLA) data for organ and tissue transplant compatibility between recipient and donors. This type of testing also has applications in ancestry testing and genetic matchmaking. HLA data of the recipient is matched with a database of possible donor HLA data while keeping the data from both parties private. Experimental results on real genome data demonstrate the practicability of GenMatch in terms of timing and communication complexity for HLA database in the order of million user profiles.","PeriodicalId":194799,"journal":{"name":"2016 IEEE International Symposium on Hardware Oriented Security and Trust (HOST)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130521382","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}

Ghosh","doi":"10.1109/HST.2016.7495552","DOIUrl":"https://doi.org/10.1109/HST.2016.7495552","url":null,"abstract":"Linear layers are crucial building blocks in the design of lightweight block ciphers, since they perform the dual task of providing the much needed diffusion, while also ensuring minimal hardware cost for implementation. Although a number of lightweight block ciphers with parsimoniously designed linear layers have been proposed in cryptographic literature, there is limited work on generic construction techniques for such linear layers, to the best of our knowledge. The challenge in designing a suitable linear layer, that combines the requirements of both cryptographic strength and lightweightedness, lies in the huge search space accompanying such a construction technique. In this paper, we propose a hierarchical linear layer construction technique that systematically combines the principles of block interleaving and wide trail design strategy to construct large linear layers from suitably chosen smaller linear layers that guarantee the necessary diffusion properties. Additionally, the smaller linear layers are realized by iterating linear layers which are extremely lightweight, thus providing us with a strategy to guarantee diffusion while ensuring that the gate count of the design is minimized. In order to demonstrate the efficiency of our proposed technique, we compare it with the general construction technique proposed for the design of the block cipher PRIDE. To the best of our knowledge, PRIDE offers the only other general construction technique that focuses specifically on the construction of lightweight linear layers. While the construction technique of PRIDE is efficient for software implementations, our technique provides 60% and 50% greater savings in terms of area footprint on ASIC and FPGA based designs respectively, with an overall area-time product reduction by 7.5%. The main contribution of this work lies in providing the cipher design community with a generic off-the-shelf technique for designing lightweight linear layers with high diffusion for hardware-oriented applications.","PeriodicalId":194799,"journal":{"name":"2016 IEEE International Symposium on Hardware Oriented Security and Trust (HOST)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115334450","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 method is provably secure by leveraging the Yao's classic Garbled Circuit (GC) protocol. While the concept of using GC for secure fingerprint matching has been suggested earlier, to the best of our knowledge, no prior reliable method or implementation applicable to real fingerprint data has been available. Our technique achieves both accuracy and practicability by customizing a widely adopted minutiae-based fingerprint matching algorithm, Bozorth matcher, as our core authentication engine. We modify the Bozorth matcher and identify certain sensitive parts of this algorithm. For these critical parts, we create a sequential circuit description which can be efficiently synthesized and customized to GC using the TinyGarble framework. We show evaluations of our modified matching algorithm on a standard fingerprint database FVC2002 DB2 to demonstrate its reliability.

Tehranipoor","doi":"10.1109/HST.2016.7495548","DOIUrl":"https://doi.org/10.1109/HST.2016.7495548","url":null,"abstract":"While Radio Frequency Identification (RFID) has become popular for commodity and asset tracking and management, the relatively higher price of RFID tags limits its application in the supply chain of low-cost commodities. Recently, cost-effective chipless RFID tags that do not contain a microchip in the transponder have been gaining more attention from industry, academia, and government. Existing chipless RFID tags require removing or shorting of some resonators (i.e., spirals or patch slots) on the substrate to encode data, but this incurs a waste of tag area and increases the manufacturing time/cost of chipless RFID tags. In addition, the identifiers (IDs) generated by existing chipless RFID tags are small, deterministic, and clonable. To mitigate these shortcomings, we propose a new unclonable chipless RFID (UCR) tag that intrinsically generates a unique ID from manufacturing variations. UCR tag consists of a certain number of concentric ring slot resonators, whose resonance frequencies depend on slot parameters and substrate dielectric constant that are sensitive to manufacturing variations. The area of UCR tag is as small as regular quick response (QR) code. Simulation results based on CST Microwave Studio 2015 have verified the effectiveness and reliability of UCR tags. The non-overlapping margin between intra-tag and inter-tag Euclidian distance distributions reaches approximately 50 MHz in the presence of random white Gaussian noise (WGN) with a signal-to-noise ratio (SNR) of 10 dB.","PeriodicalId":194799,"journal":{"name":"2016 IEEE International Symposium on Hardware Oriented Security and Trust (HOST)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130445376","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}

Güneysu","doi":"10.1109/HST.2016.7495565","DOIUrl":"https://doi.org/10.1109/HST.2016.7495565","url":null,"abstract":"Physical Unclonable Functions (PUFs) are a promising way to securely generate and store keys by using the inherent process variations of each chip as a source of randomness. One of the most promising PUFs for FPGAs is the Ring-Oscillator (RO) PUF. In this paper we take a closer look at RO PUFs and their open challenges. Starting from a reference design for a Spartan-6 FPGA based on PUFKY, we show how the RO design can be optimized by taking full advantage of the available resources, reducing the RO area by nearly 50%. Furthermore, we analyze the observed structural bias of the RO PUFs and show how the entropy of the RO PUF can be improved by taking the FPGA structure into account when extracting the PUF response bits. However, we also point out a very important problem of FPGA based RO PUFs that has not gained the needed attention: counter failures. We show that the frequency counter is a very crucial element in RO PUF design that itself is very susceptible to process variations. While the counters might work properly on most devices, in some they fail to count correctly. For example, in one experiment only one out of 22 FPGAs failed to count correctly. Our results therefore show that the correct functioning of the frequency counter is not only design-dependent, but also depends highly on process variations, i.e., on the individual FPGA. We argue that solving this issue is non-trivial, since the internal details of the FPGA are secret and hence circuit-level simulations of an FPGA design are not possible. However, the large security implications of such failures make it inevitable that this problem is solved before RO PUFs on FPGAs can be used in practice.","PeriodicalId":194799,"journal":{"name":"2016 IEEE International Symposium on Hardware Oriented Security and Trust (HOST)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131634798","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}
