Traditional auditing techniques generate large and inaccurate causal graphs. To overcome such limitations, researchers proposed to leverage execution partitioning to improve analysis granularity and hence precision. However, these techniques rely on a low level programming paradigm (i.e., event handling loops) to partition execution, which often results in low level graphs with a lot of redunda...

Wireless Sensor Network (WSN) consists of large number of sensor nodes capable of forming instantaneous network with dynamic topology. Each node simultaneously as both router and host. Number of nodes in a WSN can vary either due to the mobility or death of nodes due to drained conditions. Low Energy Aware Cluster Hierarchy (LEACH) is a most popular dynamic clustering protocol for WSN. Deployme...

We propose a new threat-base search algorithm which takes into account threats by both players. In full-board Semeais in Go or Shogi endgames, making naive attack moves often result in losing the game. The reason is that a player must first make a defense move if the opponent has a better attack move than his own. Some attack moves weaken the defense of the player who made the move. Thus, playe...

Mobile Ad hoc Networks (MANET) have been highly vulnerable to attacks due to the dynamic nature of its network infrastructure. Among these attacks, routing attacks have received considerable attention since it could cause the most devastating damage to MANET. Even though there exist several intrusion response techniques to mitigate such critical attacks, existing solutions typically attempt to ...

An agent is anything that can be viewed as perceiving its environment through sensors and acting upon that environment through effectors. Enormous number of researches is going on by comparing the functional similarities of the Human Immune System for making the agents more adaptable in regard with security. In this research work, the functional similarities of Human Nervous system are given to...

recently, baghery et al. [1, 2] presented some attacks on two rfid protocols, namely yoon and jung et al. protocols, and proposed the improved version of them. however, in this note, we show that the improved version of the jung et al. protocol suffers from desynchronization attack and the improved version of the yoon's protocol suffers from secret disclosure attack. the success probabilit...

Enterprise networks face a variety of threats including worms, viruses, and DDoS attacks. Development of effective defenses against these threats requires accurate inventories of network devices and the services they are running. Traditional vulnerability scanning systems meet these requirements by periodically probing target networks to discover hosts and the services they are running. This po...

We consider the problem of defining and achieving plaintextaware encryption without random oracles in the classical public-key model. We provide definitions for a hierarchy of notions of increasing strength: PA0, PA1 and PA2, chosen so that PA1+IND-CPA → INDCCA1 and PA2+IND-CPA → IND-CCA2. Towards achieving the new notions of plaintext awareness, we show that a scheme due to Damg̊ard [12], denot...

According to high development of internet and mobile internet technologies, more and more services and applications are researched and are becoming more and more important in people’s life. At the same time, there are still many risks that virus attack from internet. Network security is facing more challenges than before, such as attack method becoming more diversify, attack times are increasin...

Providers of next-generation ubiquitous services are facing increasing competition. In order to attract and satisfy customers, these services must offer added value e.g. by delivering personalized information in a seamless and multi-modal way. Personalized services, however, bring about additional requirements related to privacy and security, which have to be addressed if the services are to be...
