Cyber security is dynamic as defenders often need to adapt their defense postures. The state-ofthe-art is that the adaptation of network defense is done manually(i.e., tedious and error-prone). The ideal solution is to automate adaptive network defense, which is however a difficult problem. As a first step towards automation, we propose investigating how to attain semi-automated adaptive network defense(SAND). We propose an approach extending the architecture of software-defined networking, which is centered on providing defenders with the capability to program the generation and deployment of dynamic defense rules enforced by network defense tools. We present the design and implementation of SAND, as well as the evaluation of the prototype implementation. Experimental results show that SAND can achieve agile and effective dynamic adaptations of defense rules(less than 15 ms on average for each operation), while only incurring a small performance overhead.

An integrated laser diode driver(LDD) driving an edge-emitting laser diode was designed and fabricated by 0.35 μm BiCMOS technology. This paper proposes a scheme which combines the automatic power control loop and temperature com-pensation for modulation current in order to maintain constant extinction ratio and average optical power. To implement tem-perature compensation for modulation current,a novel circuit which generates a PTAT current by using the injecting base current of a bipolar transistor in saturation region,and alternates the amplifier feedback loop(closed or not) to control the state of the current path is presented. Simulation results showed that programmed by choice of external resistors,the IC can provide modu-lation current from 5 mA to 85 mA with temperature compensation adjustments and independent bias current from 4 mA to 100 mA. Optical test results showed that clear eye-diagrams can be obtained at 155 Mbps,with the output optical power being nearly constant,and the variation of extinction ratio being lower than 0.7 dB.

Outsourced data in cloud and computation results are not always trustworthy because data owners lack physical possession and control over the data as a result of virtualization, replication, and migration techniques. Protecting outsourced data from security threats has become a challenging and potentially formidable task in cloud computing;hence, many schemes have focused on ameliorating this problem and on enabling public auditability for cloud data storage security. These schemes drop into two categories: total computation cost and burden on client side. Researchers have used bilinear map technology with public key cryptography. Although this technology is highly efficient, computation time is long and overhead cost is high. The client needs to perform numerous computations to ensure the integrity of data storage. To reduce auditing cost, we propose an efficient and robust scheme to maintain data integrity in cases that involve public auditing. Our scheme adopts modern cipher cryptography with a cryptographic hash function. We consider allowing a third party auditor to preprocess data on behalf of cloud users before uploading them to cloud service providers and then verifying data integrity afterward. Our proposed scheme has important security characteristics, such as privacy, key management, low cost computation, key exchange, low overhead cost, no burden on client side, inability of cloud service providers to create correct verifier respond without data, and one-time key. Finally, efficiency analysis shows that our scheme is faster and more cost-efficient than the bilinear map-based scheme. © 2015 IEEE.

Virtual machine (VM) technologies are becoming more and more important among industrial and academic institutions with the decreasing cost of computer hardware. It can offer a lot of benefits including performance isolation, server consolidation, and live migration. However, the development of virtualization technology is preferred to application isolation as yet, thus the performance overheads of communicate between virtual machines which are resident on the same physical machine are relatively high. In network-intensive applications, such as Internet servers, are consolidated in a physical machine using VM technology, the inter-domain shared memory communication mechanisms is necessary. In other words, nearly all the virtual machine monitors are not very efficient in I/O performance to meet these applications' requirements. As a result, some scholars resort to inter-domain shared memory mechanisms to improve data transferring performance, but some of these solutions only provide one-way tunnel for domains to communicate with each other, and others are not network-bypass, which use the existing AF-INET protocol family, and incur unnecessary overhead brought by TCP/IP stack. In this paper, we present an inter-domain data transferring system, called IDTS, with dual-way tunnels and fully network-bypass features in Xen virtual machine environment. The design of IDTS is different from virtual network scheme in that IDTS uses static circular memory buffer shared between domains instead of the Xen page-flipping mechanism. In order to enable dual-way communication, IDTS provides two shared memory tunnels for co-resident domains to communicate with each other. Our evaluation demonstrates that IDTS can reduce inter-domain round trip latency by nearly a factor of 4, and increase bandwidth by approximately 5 times, and also keep high scalability, compared with traditional TCP/IP approach.

Range query in DHT based P2P network is a hot topic in recent researches. The hashing function in DHT protocols makes the data hard to keep their original order relationship. Hence range queries for such networks become difficult. This paper presents the design of Yarqs - a new schema to achieve range queries in DHT based P2P networks. By using the inherent characteristics of DHT based networks, Yarqs catches the data pass the nodes and organizes them as a cache network. The range queries are deployed over the cache network. Yarqs does not change the design of the DHT overlay and builds the architecture for range queries by using the historical DHT queries data. Yarqs supports inherent load balancing. We also study the performance of Yarqs in evaluation section. The experiments to check the influences of different parameters of Yarqs are deployed and analyzed. © 2009 IEEE.

Interval Type-2 Fuzzy Set is the most popular kind of Type-2 Fuzzy Set, its characteristic is that all the secondary membership functions equal to 1. Though Interval Type-2 Fuzzy Sets can reduce the calculation complexity than other Type-2 Fuzzy Sets, it loses much fuzzy information simultaneously. In order to solve this problem we propose a novel theory of Triangle Type-2 Fuzzy Sets, the formulas for union, intersection and complement of Triangle Type-2 Fuzzy Sets are derived and proven in detail. In addition, the relationship and the conversion between Triangle Type-2 Fuzzy Sets and Interval Type-2 Fuzzy Sets are discussed. © 2009 IEEE.

The simulation grid has become a very important research topic. In order to ensure the QoS of resource management, we present a control mechanism in simulation grid, which is based on the prediction methods. In the control mechanism, we first introduce our resource management module in simulation grid. Then, we propose a resource allocation algorithm. In order to justify the feasibility and the availability of this control mechanism, a series of experiments have been done. The results show that it is feasible to schedule the system resources and control the QoS of system resources for tasks in simulation grid. © 2012 IEEE.
