Securing Ad Hoc Networks With "Asymmetric" Probabilistic Key Predistribution SchemesMahalingam RamkumarThe 7th IEEE Information Assurance Workshop (IAWorkshop 2006)West Point, New York, USA, June 21-23, 2006
AbstractWe present two asymmetric probabilistic key predistribution schemes to cater for mutual authentication and broadcast authentication respectively. The schemes however employ only symmetric cryptographic primitives - the asymmetry is due to the use of different secrets for encryption / authentication and decryption / verification, which are however related through a one-way function. Both schemes try to take advantage of an abundant and inexpensive resource, storage, to improve their security. While both schemes can have a wide range of applications, we limit ourselves to their utility in securing routing information in multi-hop ad hoc networks.
