Information Assurance Issues For An Sdr Operating In A Manet Network
by William T. Scott, Alain C. Houle, Antonio Martin
MANET networks are transitory, poorly regulated and essentially local in nature. Such environments have need for Information Assurance (IA) services, but the lack of regulation, the limited reach-back connectivity, and the ad hoc nature of the networks make supplying these services difficult. MANET IA services should supply subscriber confidentiality, data integrity and peer authentication, while being 1) independent of access to the larger network infrastructure, 2) resilient to a variety of attacks unique to wireless ad hoc environment, and 3) based on established industry protocols when possible. This paper proposes an approach to securing MANET networks by leveraging standard IP based security protocols such as PKIX, IKEv2 and IPSEC, and the new generation of cryptographic protocol standards e.g., MQV, AES, SHA-384 and ECDSA that supplies the required IA services within the MANET environment.
