It is challenging to design a routing scheme that can successfully operate in the presence of adversarial environment in mobile ad hoc network MANET, where several types of severe routing security threats can be easily employed against normal routing. ...

This paper investigates the use of flow size distribution as a source in entropy-based detection. The performance of detection based on this distribution is compared with the performance of detection based on simple packet distribution, namely ...

Compared with the visual-cryptography-based visual secret sharing, the random-grid-based visual secret sharing RGVSS has some technical advantages, such as no pixel expansion and no need of codebooks. Designed based on RGVSS, the user-friendly random-...

Among the principals for securing smart grid infrastructure, accountability is one with lesser addressed concepts in smart grid literature. Even further, studies in the home area network are lacking in enforcement of accountable mechanisms as assigning ...

White-box cryptography aims at implementing a cipher to protect its key from being extracted in a white-box attack context, where an attacker has full control over dynamic execution of the cryptographic software. So far, most white-box implementations ...

The existing homomorphic encryption schemes are mostly in the form of "one-to-one" deployment models, where one party usually encrypts the plaintext and another party decrypts the ciphertext in public key cryptosystem. This form of cryptography loses ...

The situation for post-challenge continuous auxiliary input leakage has not been considered in the cryptography schemes for previous literature. We present a semantic-security model with post-challenge continuous auxiliary inputs for identity-based ...

The current Internet is facing unprecedented demands, and the challenges and protocols were designed and incorporated into the system as a patchwork for solving many issues. The patchwork approach of non-integrated security mechanisms does not ...

In order to detect abnormal communication behaviors efficiently in today's industrial control system, a new intrusion detection algorithm based on One-Class Support Vector Machine OCSVM is proposed in this paper. In this algorithm, a normal ...

Future healthcare systems, smart homes, and similar will involve a large number of smart inter-connected wireless devices such as wireless sensor nodes. One of the major challenges to securing these systems presents loading initial cryptographic ...

The advent of computer networks makes network protocols - running on this unprotected environment - vulnerable against various attacks and malefactions. Hence, methods for automatic security verification of protocols in the early stages of protocol ...

This paper proposes a new two round authenticated contributory group key agreement ACGKA protocol based on elliptic curve Diffie-Hellman ECDH with integrated signature. In this technique, one node is picked up as the group controller, and this node runs ...

Computer worms have infected millions of computers since the 1980s. For an incident handler or a forensic investigator, it is important to know whether the worm attack to the network has been initiated from multiple different sources or just from one ...

Introduction of various cryptographic modes of operation is induced with noted imperfections of symmetric block algorithms. Design of some cryptographic modes of operation has already been exploited as an idea for parallelization of certain algorithms ...

Cloud security has become one of the emergent issues because of the immense growth of cloud services. A major concern in cloud security is the insider threat because of the harm that it poses. Therefore, defending cloud systems against insider attacks ...

The Internet has made the world smaller while there is still a gap between the cyber world and our physical world. In the future cyber-physical system CPS, all objects in cyber world and physical world would be connected, and the concepts of cyber world ...

This paper presents a new method for mutual authentication in centralized cognitive radio networks. In doing so, we analyzed the proposed scheme in terms of security and performance. As for security, we analyzed the proposed scheme from a mathematical ...

Khudra is a lightweight block cipher for field-programmable gate arrays, which appeared in SPACE 2014. In this paper, we consider the security of Khudra against the related-key attack. Firstly, we give some observations of F-function. Then we design a ...

Privacy and authentication are two primary aspects of many security systems. In this article, we propose a new mode of operation for block encryption called plain-text feedback XORing PFX, which can assure both confidentiality and message integrity ...

In this paper, we propose two secure virtual private network architectures for the long-term evolution backhaul network. They are layer 3 Internet protocol IP security virtual private network architectures based on Internet key exchange version 2 ...

Advances in communication allow people flexibility to communicate in various ways. Electronic mail email is one of the most used communication methods for personal or business purposes. However, it brings one of the most tackling issues, called spam ...

Pervasive computing constitutes a growing trend, aiming to embed smart devices into everyday objects. The limited resources of these devices and the ever-present need for lower production costs, lead to the research and development of lightweight ...

A prominent software security violation-buffer overflow attack has taken various forms and poses serious threats until today. One such vulnerability is return-oriented programming attack. An return-oriented programming attack circumvents the dynamic ...
