Indian cities are seen with predominantly mixed traffic plying on the streets. Modeling involving vehicles characterised of different speed, length, and width is a challenging issue. Based finer cell system cellular automata (CA) models, this paper proposes to evaluate behavior cars motorcycles for intermediate lane width, which more common in cities. The maximum car flow observed (even presenc...

We propose a novel stream data classification technique to detect Peer to Peer botnet. Botnet traffic can be considered as stream data having two important properties: infinite length and drifting concept. Thus, stream data classification technique is more appealing to botnet detection than simple classification technique. However, no other botnet detection approaches so far have applied stream...

Label-switching technology enables high performance and flexible layer-3 packet forwarding based on the fixed-length label information that is mapped to the layer-3 packet stream. A label-switching router (LSR) forwards layer-3 packets based on their layer-3 address information or their label information that is mapped to the layer-3 address information. Two label-mapping policies have been pro...

This paper puts forward an efficient and optimized method to determine the probable-colluders in a MD5 based cryptosystem. Along with the conventional MD5 implementing architecture, our scheme employs a predictor control block which takes the message stream from the user, and provides the log-list of the equal length bit-streams that are most likely to produce collisions with the message stream...

In this paper, we analyze the security of the stream cipher Helix, recently proposed at FSE’03. Helix is a high-speed asynchronous stream cipher, with a built-in MAC functionality. We analyze the differential properties of its keystream generator and describe two new attacks. The first attack requires 2 basic operations and processes only 2 words of chosen plaintext in order to recover the secr...

This paper presents Dragon, a new stream cipher constructed using a single word based non-linear feedback shift register and a nonlinear filter function with memory. Dragon uses a variable length key and initialisation vector of 128 or 256 bits, and produces 64 bits of keystream per iteration. At the heart of Dragon are two highly optimised 8 × 32 s-boxes. Dragon uses simple operations on 32-bi...

The Self-shrinking p-adic cryptographic generator (SSPCG) is a fast software stream cipher. Improved cryptoanalysis of the SSPCG is introduced. This cryptoanalysis makes more precise the length of the period of the generator. The linear complexity and the cryptography resistance against most recently used attacks are invesigated. Then we discuss how such attacks can be avoided. The results show...

We investigate whether the recently discovered Phoenix stream may be part of a much longer stream that includes the previously discovered Hermus stream. Using a simple model of the Galaxy with a disk, bulge, and a spherical dark matter halo, we show that a nearly circular orbit, highly inclined with respect to the disk, can be found that fits the positions, orientations, and distances of both s...

A simple analytical model is presented for the removal of stream-borne contaminants by hyporheic exchange across duned or rippled streambeds. The model assumes a steady-state balance between contaminant supply from the stream and first-order reaction in the sediment. Hyporheic exchange occurs by bed form pumping, in which water and contaminants flow into bed forms in high-pressure regions (down...

Streamline seeding algorithms have a long and rich history dating back over two decades. And in recent years algorithms for stream surface placement have been developed. However, stream ribbons have been generally overlooked. We present, to our knowledge, the first stream ribbon seeding strategy. Stream ribbons are a tool for visualizing vector fields and are a common extension of streamlines w...
