A Denial of Service (DoS) attack is a malicious effort to keep endorsed users of a website or web service from accessing it, or limiting their ability to do so. A Distributed Denial of Service (DDoS) attack is a type of DoS attack in which many computers are used to cripple a web page, website ...

In this paper, the authors suggest that the combination of state-transition graph and cause-effect graph is an excellent solution of test oracles problems. The empirical setup for ‘Student admission process’ presented in this paper has been implemented to encourage test results. The suggested approach contains UML and OCL architectures, as input in which the combination ...

In modern world of communication systems, various new methods have developed to replace the previous conventional techniques that provide data communication with high speed. As wireless communication guidelines were developed it became necessary to develop new techniques like Orthogonal Frequency Division Multiplexing (OFDM) for data security and reliability while data transmission. Idea behind the high ...

To harness the safe operation of web-based systems in web Environments, the authors propose an SSPA (Server based SHA-1 Page digest Algorithm) to verify the integrity of web contents before the server issues an HTTP response to a user request. In addition to standard security measures, their Java implementation of the SSPA, which is called ...

Time alone anxiety in online community system forces have encouraged a numeral of suggestion for Decentralized Online Social Networks community system (DOSN) that eliminate the innermost supplier and plan at generous the consumer organize more than their information and who can contact it. This is typically finished by cryptographic resources. Existing DOSNs use cryptographic primitives ...

The Profile matching means that 2 users scrutiny their personal profiles and is usually the primary step towards effective. It, however, conflicts with users’ growing privacy issues regarding revealing their personal profiles to finish strangers before deciding to move with them their protocols modify 2 users to perform profile matching while not revealing any data ...

Some issues in these categories were addressed by multi-sensor application or sensor fusion. However, advancement in technology and advent of wireless sensors in a networked environment, brought along a new risk factor related to the security in wireless sensor network. Therefore security in Wireless Sensor Network WSNs is challenging and critical to the functionality of ...

Wireless sensor network and its applications are intriguing research that has been concentrated as of late. Battery utilization of sensor nodes is the principle issue in the group of wireless sensor that ought to be sorted out. In this way, to expand the adaptability of the system, and to diminish the energy usage for general ...

In this paper, the authors deal with the black hole attack prevention and its effect on network performance and then optimization using ACO (Ant Colony Optimization) approach is done in which fitness function optimization takes place. The packets transmitted in this way are made to drop so as no unauthorized access is available to transmit ...

Mobile Ad hoc NETwork (MANET) is a self-coordinated system which is intended through a group of mobile nodes with wireless links deprived of using any consolidated infrastructure. Communication between nodes occurs with the help of different routing protocol. The absence of centralized administration makes it vulnerable to various attacks. Worm hole attack is considered to ...
