A new ad hoc group key agreement scheme

For the characteristics of ad hoc networks, group key management analysis of the current research results and problems, group key management protocol based on NTRU public key cryptosystem was proposed. Trusted center offline to generate key and other initialization parameters for each member of the group. In the group key agreement process useing the NTUR digital signature to realize the user and the private key information authentication. The correctness and security of the protocol are proof.. In satisfies ad hoc network security conditions, The agreement is simple in design and requires limited calculation and limited storage space etc benefits.
