Study of Key Distribution and Management for Wireless Ad-Hoc

According to infrastructure-less and Low resource availability property of Ad-Hoc network,the solution of new security problems which Ad-Hoc faces is proposed and its practical applications is improved.Using recently developed concepts of identity-based cryptography and threshold cryptography,a distributed key distribution and authentication approach in Ad-Hoc networks is constructed for Ad-Hoc and no infrastructure.The most significant advantage of the scheme lies in the enhancement of security while reducing the communication overhead and resource consumption and saving network bandwidth.The security of the key management in Ad-Hoc network is efficiently resolved.
