Infrastructures less network is MANET which creates the temporary network. Performance and security are its two major issues. Due to its self organizing feature providing runtime network security is tedious task. So an efficient and strong model is required to setup so that various eavesdropping activity can be avoided. Key management is a vital part of security in Manet because the distribution of encryption keys in an authentication manner is a difficult task due to its dynamic nature. As every time nodes leaves or joins it has to regenerate a new session key for maintaining secrecy. In this paper, we have proposed a new key management scheme to improve the network security with less mobility overhead and less key distribution time .

A Framework to improve the Network Security with Less Mobility in MANET

Secure routing is the milestone in mobile ad hoc networks. Ad hoc networks are widely used in military and other scientific areas with nodes which can move arbitrarily and connect to any nodes at will, it is impossible for Ad hoc network to own a fixed infrastructure. It also has a certain number of characteristics which make the security difficult. Routing is always the most significant part for any networks. We design a trust based packet forwarding scheme for detecting and isolating the malicious nodes using the routing layer information. This paper gives an overview about trust in MANETs and current research in routing on the basis of trust. It uses trust values to favor packet forwarding by maintaining a trust counter for each node. A node will be punished or rewarded by decreasing or increasing the trust counter. If the trust counter value falls below a trust threshold, the corresponding intermediate node is marked as malicious.

New trust based security approach for ad-hoc networks

Background: Pericoronal tissue is the soft tissue located between the bony crypt and the impacted tooth, which is histologically composed of fibrous connective tissue and is usually lined by the reduced enamel epithelium. Increased epithelial cell proliferation in the pericoronal tissue is associated with pathological changes such as development of an odontogenic cyst or an epithelial odontogenic tumor. This study is an attempt to evaluate and compare the proliferative index in the epithelium surrounding the impacted third molar teeth, dentigerous cysts, and gingiva. Materials and Methods: A case control study on pericoronal tissues and dentigerous cysts was carried out using immunomarkers. Forty pericoronal tissues were obtained from asymptomatic impacted third molars with pericoronal radiolucency less than 2.5 mm. Samples of 20 dentigerous cysts and normal gingiva were also included. Routine hematoxylin and eosin and immunostaining for Ki‑67, a cell proliferation marker and Bcl‑2, an anti apoptotic protein were performed on sections of pericoronal tissues, dentigerous cysts, and gingival tissues. The percentage of Ki‑67‑positive cells and Bcl‑2 positive areas was found using the DigiPro™ version 4.0 Image analysis software. Bcl‑2 immunopositivity and Ki‑67‑Li were analyzed using the Chi‑square test and paired t‑test. P‑ values of less than .05 were considered to indicate statistical significance. Results: The immunohistochemical analysis revealed overexpression of Bcl‑2 in the pericoronal tissues with squamous metaplasia, which was comparable to the dentigerous cyst. Ki‑67 Li of the pericoronal tissue with squamous metaplasia was equal to the proliferative index of the dentigerous cyst. The expression of Ki‑67 Li and inflammatory cells were highly significant ( P < 0.0001). Conclusions: The results of this study indicate that the pericoronal tissues of asymptomatic impacted third molars may be actively proliferating and normal pericoronal radiolucency cannot serve as an indicator for the differentiation potential.
