Disruption of Black Hole attacks in MANET

An Ad hoc network in a wireless system consist of an autonomous system, without centralization which results forming of mobile nodes. In MANET, each node works in a dual form that consists of a router as well as hosts. These nodes configure dynamically and communicate using hop to hop. Due to its simplicity it is used in mobile conferencing, military communication. In MANET nodes can join and leave the network so MANET becomes vulnerable. Certain factors like dynamic network configures, distribution cooperation, open medium terrorized in routing which give rise to security issues. Once such protocol AODV has been a victim of security. In existing, MANET faces a severe problem known as the Black Hole problem. This Black hole problem is mostly found in reactive routing protocol called AODV.The black hole conducts its Malicious node during route discovery process. Black hole node is a severe threat in AODV protocol that easily employed and becomes vulnerable in MANET. In this paper various techniques are discussed to overcome the Black hole attack

Certificateless and provably-secure digital signature scheme based on elliptic curve

With the internet today available at the user’s beck, and call data or Information Security plays a vital role. Confidentiality, Integrity, Availability, and Non-repudiation are the pillars of security on which every application on the web is based on. With these basic requirements the users also need the security in low resource constrained environments making it more challenging for the security experts to design secured cryptographic algorithms. Digital Signatures play a pivotal role in Authentication. They help in verifying the integrity of the data being exchanged. Elliptical curves are the strongest contenders in Digital Signatures, and much research is being done to enhance the method in many ways. The paper briefs a secured and improved ECDSA Elliptical Curve Digital Signature Algorithm which is an improved and secured version of the Digital Signature Algorithm

Implementation of ECC and ECDSA for Image Security

the use of digital data has been increase over the past decade which has led to the evolution of digital world. With this evolution the use of data such as text, images and other multimedia for communication purpose over network needs to be secured during transmission. Images been the most extensively used digital data throughout the world, there is a need for the security of images, so that the confidentiality, integrity and availability of the data is maintained. There is various cryptography techniques used for image security of which the asymmetric cryptography is most extensively used for securing data transmission. This paper discusses about Elliptic Curve Cryptography an asymmetric public key cryptography method for image transmission. With security it is also crucial to address the computational aspects of the cryptography methods used for securing images. The paper proposes an Image encryption and decryption method using ECC. Integrity of image transmission is achieved by using Elliptic Curve Digital Signature Algorithm (ECDSA) and also considering computational aspects at each stage

Security in Proactive Mobile Ad Hoc Network Routing Protocols

A mobile ad hoc network (MANET) is a repetitively self-configuring, mobile wireless node. Routing can takes place proactively (table-driven), reactively (on demand) or in a hybrid manner. This paper, attempts to contribute a discussion on various security issues and various security aspects related to overcome these security issues found in Proactive Mobile Ad Hoc Network routing protocols. This paper also presents a comparison between two proactive routing protocols on various security parameters. DOI: 10.17762/ijritcc2321-8169.150712

An Attempt to Improve Data Security in Text Based Cryptosystem Using Elliptic Curve Cryptography

Data can be debilitated by hackers and spies. Cryptography helps us find better approaches to secure information in digital form. Elliptic Curve Cryptography (ECC) is favorable over numerous cryptographic systems because of smaller keys and quick key generation. This paper proposes a system which intends to provide multifold security in text based communication. The system has two main modules: encryption, and decryption. Encoding scheme which works on variable length text block mapping technique has been exhibited, thereby enhancing data security provided by ECC in text based cryptosystems. To leverage the advantages of ECC, it is being used in many applications. This papers attempts to utilize ECC in text based cryptosystems efficiently
