Consider the well-known oracle attack: somehow one gets a certain computation result as a function of a secret key from the secret key owner and tries to extract some information on the secret key. This attacking scenario is well understood in the cryptographic community. However, there are many protocols based on the discrete logarithm problem that turn out to leak many of the secret key bits ...

radio frequency identification (rfid) applications have spread all over the world. in order to provide their security and privacy, researchers proposed different kinds of protocols. in this paper, we analyze the privacy of a new protocol, proposed by yu-jehn in 2015 which is based on electronic product code class1 generation 2 (epc c1 g2) standard. by applying the ouafi_phan privacy model, we s...

This paper presents a scheme for detecting anomalous power consumption patterns attack using wavelet transform and artificial neural network for smart grid. The main procedure of the proposed algorithm consists of following steps: I) Creating normal and anomaly patterns of power consumption to train the proposed method. II) Wavelet transform is applied on power consumption patterns to extract f...

Mobile Adhoc Networks have become a part and parcel of technology advancements due to its working as autonomous system. MANET networks are vulnerable to various types of attacks and threats due to its unique characteristics like dynamic topology, Shared physical medium, distributed operations and many more. There are many attacks which effect the functioning of MANETS’ such as denial of service...

The aim of the minimization analysis of network attack graphs (NAGs) is to nd a minimum critical set of exploits so that by preventing them an intruder cannot reach his goal using any attack scenario. This problem is, in fact, a constrained optimization problem. In this paper, a binary particle swarm optimization algorithm, called SwarmNAG, is presented for the minimization analysis of large-sc...

Attack pattern system exhibits a unique property of pattern sequential cascading nature which can be identified during the design phase of an application system implementing security scenarios. In this paper a mathematical framework of secure system of attack patterns is presented to verify the stated design specification property along with theoretical back ground work. The framework defines 1...

The premise of automated alert correlation is to accept that false alerts from a low level intrusion detection system are inevitable and use attack models to explain the output in an understandable way. Several algorithms exist for this purpose which use attack graphs to model the ways in which attacks can be combined. These algorithms can be classified in to two broad categories namely scenari...

Security-aware embedded devices which are likely to operate in hostile environments need protection against physical attacks. For the RSA public-key algorithm, protected versions of the Montgomery powering ladder have gained popularity as countermeasures for such attacks. In this paper, we present a general fault attack against RSA implementations which use the Montgomery powering ladder. In a ...

Once an attacker has compromised a set of machines, typically, he will repeatedly deploy the same set of machines to attack different targets. In this paper, we propose a method to identify repeated attack scenarios, that is, the combination of a particular set of hosts and attack tool, by making use of pattern recognition techniques. While previous methods have focused on intrusion detection u...

The cube attack is a powerful cryptanalytic tool for the analysis of stream ciphers, which until recently were investigated in a blackbox scenario with a minimal consideration to their internal and polynomial structures. In this paper, we analyze the lightweight stream cipher WG5, which offers 80-bit security, using cube attacks in a non-blackbox polynomial setting employing the division proper...
