Permanent repository link AbstractAs the world becomes an interconnected network where objects and humans interact with each other, new challenges and threats appear in the ecosystem. In this interconnected world, smart objects have an important role in giving users the chance for life-logging in smart environments. However, smart devices have several limitations with regards to memory, resources and computation power, hindering the opportunity to apply well-established security algorithms and techniques for secure life-logging on the Internet of Things (IoT) domain. The need for secure and trustworthy life-logging in smart environments is vital, thus, a lightweight approach has to be considered to overcome the constraints of smart objects. The purpose of this paper is to present in details the current topics of life-logging in smart environments, while describing interconnection issues, security threats and suggesting a lightweight framework for ensuring security, privacy and trustworthy life-logging. In order to investigate the efficiency of the lightweight framework and the impact of the security attacks on energy consumption, an experimental test-bed was developed including two interconnected users and one smart attacker, who attempts to intercept transmitted messages or interfere with the communication link. Several mitigation factors, such as power control, channel assignment and AES-128 encryption were applied for secure life-logging. Finally, research into the degradation of the consumed energy regarding the described intrusions is presented.

“…Through the second round, nearly all of the eliminated algorithms were found to suffer from either efficiency or security flaws. Furthermore, despite suffering from minor security issues, some of the high-performing candidates survived the elimination process [35]; this clearly highlights the importance of efficiency in the evaluation procedure.…”

Abstract. The NIST hash function competition to design a new cryptographic hash standard 'SHA-3' is currently one of the hot topics in cryptologic research, its outcome heavily depends on the public evaluation of the remaining 14 candidates. There have been several cryptanalytic efforts to evaluate the security of these hash functions. Concurrently, invaluable benchmarking efforts have been made to measure the performance of the candidates on multiple architectures. In this paper we contribute to the latter; we evaluate the performance of all second-round SHA-3 candidates on two exotic platforms: the Cell Broadband Engine (Cell) and the NVIDIA Graphics Processing Units (GPUs). Firstly, we give performance estimates for each candidate based on the number of arithmetic instructions, which can be used as a starting point for evaluating the performance of the SHA-3 candidates on various platforms. Secondly, we use these generic estimates and Cell-/GPU-specific optimization techniques to give more precise figures for our target platforms, and finally, we present implementation results of all 10 non-AES based SHA-3 candidates.

“…Following the completion of the first round of the NIST SHA-3 hash algorithm competition in September 2009, fourteen candidates have been selected to participate in the second round [16]. As such, developing and benchmarking software and hardware implementations of these remaining hash functions is key to assess their practicality on various platforms and environments.…”

Abstract. In this paper, we present an efficient FPGA implementation of the SHA-3 hash function candidate Shabal [6]. Targeted at the recent Xilinx Virtex-5 FPGA family, our design achieves a relatively high throughput of 2 Gbit/s at a cost of only 153 slices, yielding a throughputvs.-area ratio of 13.4 Mbit/s per slice. Our work can also be ported to Xilinx Spartan-3 FPGAs, on which it supports a throughput of 800 Mbit/s for only 499 slices, or equivalently 1.6 Mbit/s per slice. According to the SHA-3 Zoo website [1], this work is among the smallest reported FPGA implementations of SHA-3 candidates, and ranks first in terms of throughput per area.
