Improving security for smart grid with multilayer consensus ECC based pake protocol (SGMCEP)
The paper aims in providing a securely communicating of data between the devices which are nothing but appliance of Home Area Network (HAN) by a set of controller outside the HAN. The packets generated by the controller should be delivered fast without any interruption. The role of an HAN controller is like a gateway, whose role is to filter the incoming packet. Due to this HAN controller, the data in the packets should not be modified & it should not cause any delay in encryption & decryption of the packets.

Effective relative position detection for multicasting of alert messages
This information can be shared with other nodes in the network and is central requirement for VANET application like navigation, intelligent transportation, collision avoidance and location based services. In case of emergency all the vehicles in the network are not affected so broadcasting of alert packet is not feasible rather multicasting of alert packet should be done, but defining the list of node to be considered for multicasting is a challenging task as every vehicle cannot hold the location information of all the vehicles in the network.

Securing the sip communications with XML security mechanisms in VoIP application awareness
The intelligent network is a basis to establish and commercialize the services by the telecommunication network. Selling services and information by a network does not define solely a considerable increase of the sum of the information flowing by the network, but also a question of confidentiality and integrity. These papers discuss and proposes a methods based on the integration of signaling protocol SIP on IN for realize a procedure of client authentication and data confidentiality.

Hybrid invasive weed optimization algorithm with chicken swarm optimization algorithm to solve global optimization problems
In this paper, a new hybrid algorithm was proposed to solve the global optimization problems that combine the invasive weed optimization algorithm with the chicken swarm optimization algorithm. The invasive weed optimization (IWO) algorithm is a stochastic algorithm inspired by the colonial behavior of weeds that was first proposed in 2006 by Mehrabian and Lucas.

Proposing a new model to improve alert detection in intrusion detection systems
In this article, a method has been presented in which the above mentioned shortcoming will be reduced by semantic expansion of alerts’ information. We will show that semantic expansion of alerts’ information based on background knowledge before clustering step leads to a much better clustering. DARPA dataset is used to evaluate the proposed method. Alerts’ detection rate will be more than 96%, which is better than similar approaches.

Simplified tcp based communication approach towards domain name system for improving security
By exploiting this vulnerability the attacker can launch different types of attacks like Cache Poisoning, DNS Spoofing, Protocol corruption, Zone corruptions, Session Hijacking, etc. Although the use of UDP makes the system faster, ye, it is suggested that all DNS based communications should be TCP based rather than UDP.
