Traffic analysis is typically countered by the use of intermediary nodes, whose role is to perturb the traffic flow and thus confuse an external observer. Such intermediaries are called mixes. We address attacks that exploit the timing behaviour of TCP and other protocols and applications in low-latency anonymity networks. Intermediaries delay and reroute exchanged messages, reorder them, pad t...

Secure socket layer (SSL) is the most popular protocol to secure Internet communications. Since SSL handshake requires a large amount of computational resource, batch RSA was proposed to speedup SSL session initialization. However, the batch method is impractical since it requires a multiple of certificates. In this paper, we overcome this problem without modifying SSL protocol. To select the o...

Batching orders and routing order pickers is a commonly studied problem in many picker-to-parts warehouses. The impact of individual differences in picking skills on performance has received little attention. In this paper, we show that taking into account differences in the skills of individual pickers when assigning work has a substantial effect on total batch execution time and picker produc...

An improved particle swarm optimization (PSO) algorithm is proposed to solve a typical batching problem in a batch processing plant of the process industry. The batching problem (BP) is to transform the primary requirements for products into sets of batches for each task with the objective of minimizing the total workload. On the basis of some preliminary properties, a novel particle solution r...

The tradeoffs in employing multicasting technology for implementing large scale video on demand (VoD) over Internet Protocol Television (IPTV) system, in general, come to the scheduled multicasting streams and limited video or television program selections. The scheduling strategies presented in this paper will provide several advantages. First, we proposed a near Video on demand architecture c...

Multi-character recognition in arbitrary photographs on mobile platform is difficult, in terms of both accuracy and real-time performance. In this paper, we focus on the domain of hand-written multi-digit recognition. Convolutional neural network (CNN) is the state-of-the-art solution for object recognition, and presents a workload that is both compute and data intensive. To reduce the workload...

Production decisions in a manufacturing supply chain are no longer driven by manual systems based on instinct and experience. They are regulated interactions between analysts, production managers and their collective manipulation of policies within the production information system. This paper studies the demand behavior in manufacturing supply chains and its relationships to the logic of produ...
