Weaknesses derived from Through-Silicon-Vias (TSV)-based physical configurations of three-dimension Multiprocessor System-on-Chip (3D-MPSoC) can be exploited by malicious software to attack the system. By means of vertical communication manipulation an attacker is able to modify, spy and even denial the TSV communication. In this paper we propose 3D-LeukoNoC, a flexible and efficient security architecture based on 3D-NoC communication structure which, as the biological immune system, is able to detect attacks, isolate sensitive vertical communication while guaranteeing the correct system behavior. We compare our approach with several 3D-protection proposals, including the simple extension of 2D security countermeasures. We show that our solution outperforms other approaches with respect to attack detection while decreasing cost and performance impact on the system.

IEEE International Symposium on Consumer Electronics (ISCE)

Network coding (NC) is a promising method used to achieve the channel capacity and enhance the reliability of multicast networks. However, the general wireless multicast networks based on NC are facing big problems such as long delays and large computational complexities. We propose a multicast network based on Batched sparse (BATS) codes which can efficiently solve these problems. Since fountain codes can also improve the reliability of wireless networks. We thoroughly compare the performance of BATS codes with that of fountain codes under our proposed networks. Simulation findings indicate that the proposed scheme results in much less transmission delay with minor complexity loss compared to fountain codes. Through analysis and simulation, we demonstrate that BATS codes perform much better than digital fountain codes in the aspects of throughput and overhead at the transmitter. It is also further shown that BATS codes are more robust against high packet loss.

In this paper, we present schemes on implementing the single-photon-added coherent source in quantum key distributions. We apply this source in either the standard BB84 protocol or the recently proposed measurement-device-independent quantum key distribution, comparing their performance with the cases of using other existing sources, e.g., the weak coherent source or the heralded single-photon source, and giving out corresponding numerical simulations. Our simulation results show that in both protocols the single-photon-added coherent source can greatly exceed all other existing sources. Moreover, even when taking statistical fluctuation into account, a high key generation rate can still be achieved at long distance by applying this source.

Three dimension Multi processors System-on-Chip (3D-MPSoCs) hold promises to allow the development of compact and efficient devices. They support many applications on the same die, able of being mapped dynamically during the execution time. Each application may have different communication requirements. Quality-of-Service (QoS) can be implemented at the communication structure (CS) to support the communication requirements of the dynamic 3D-MPSoC. Our work proposes QoS 3D-HoC, a new 3D-CS that implements the QoS. We evaluate the performance of our architecture over several 3D-MPSoC synthetic and real traffic scenarios and estimate their impact overall CS performance. We compare our architecture against the previous 3D-CS with and without QoS and show that our approach meets the communication requirements while reducing the latency and power up to 87% and 39%, respectively when compared to single 3D-NoC. © 2013 IEEE.

Social sensing enhanced time estimation for bus service

Concurrency and Computation: Practice and Experience 2015年第15期27卷

The precise prediction of bus routes or the arrival time of buses for a traveler can enhance the quality of bus service. However, many social factors influence people's preferences for taking buses. These social factors may include heavy traffic cost, traffic congestion, poor air quality and so forth. Existing prediction techniques rarely consider social sensing when predicting the bus arrival time. Accordingly, this paper proposes a social sensing enhanced service for predicting bus routes, which integrates sensing ability and social networks to understand and measure the influence between social events and vehicle velocity. We focus on the analysis of two different attributions: PT service quality attributions PEA s and road condition attributions PRCA s. Both of them synthesize the social sensing in their evaluation of bus routes. PEA represents individual preferences and PRCA represents physical factors that significantly influence vehicle velocity. Bus relevant social events were further categorized into PEA events or PRCA events. PEA s of buses were scored according to the tendency of bus conditions reflected in social events. Furthermore, an artificial neural network prediction model is established to estimate the bus travel time. Copyright © 2015 John Wiley & Sons, Ltd.

Three-dimension Multiprocessors System-on-Chip (3D-MPSoCs) hold promises to allow the development of compact and efficient devices. By means of such technology, multiple applications are supported on the same chip, which can be mapped dynamically during the execution time. This flexibility offered by the 3D technology, also represents vulnerability, turning the 3D-MPSoC security into a challenging task. 3D communication structures (3D-HoCs), which combine buses and network-on-chip can be used to efficiently overcome the present 3D-MPSoC vulnerabilities. 3D-HoCs can be used to implement different security services, monitor the data exchange and isolate dangerous IPs. In this paper, we implement Quality of Security Service (QoSS) in 3D-HoC to efficiently detect and prevent attacks by means of agile and dynamic security firewalls. Such a method takes advantage of the 3D-HoC wide system visibility and critical role in enabling system operation. We evaluate the effectiveness of our approach over several 3D-MPSoCs attack scenarios and estimate their impact on the overall performance. Results show that our architecture can perform a fast detection of a wide range of attacks and a fast configuration of the different security policies.

Three dimensional Multiprocessor System-on-Chip (3D-MPSoC) adoption. It is characterized by the integration of a large amount of hardware components on a single multilayer chip. However, heating is one of the major pitfalls of the 3D-MPSoCs. Three dimensional Network-on-Chip (3D-NoC) is used as the communication structure of 3D-MPSoCs. Its main role in system operation and performance makes the optimal 3D-NoC design a critical task. Final 3D-NoC configuration must fulfill all the application requirements and heating constraints of the system. Topology and mapping are some of the most critical parameters in 3D-NoC design, strongly influencing the 3D-MPSoC performance and cost. 3D-NoC topology and mapping has been solved for single application systems on homogeneous 3D-NoCs using single and multi-objective optimization algorithms. In this paper we use a multi-objective immune algorithm (MIA), to solve the multi-application 3D-NoC topology and mapping problems. Latency and power consumption are adopted as the target multi-objective functions constrained by the heating function. Our strategy has been applied on 8 3D-MPSoC benchmarks. Their final 3D-NoC configurations have up to 73% power and 42% latency enhancement when compared to previous reported results.
