Aircraft Identification Technique using Public-Key Cryptosystem

A new approach for identifying a friend aircrafts from foe (IFF) using public-key cryptosystem is introduced. Two schemes of public-key cryptosystem namely: RSA and knapsack public-keys are considered, which provide higher security than conventional identification methods. The practical aspects of using such systems for aircraft identification purposes are discussed. Computer simulation examples are also presented to illustrate the identification procedure.
