Query: Narayana Sequences for Cryptographic Applications   This paper investigates the randomness and cryptographic properties of the
Narayana series modulo p, where p is a prime number. It is shown that the
period of the Narayana series modulo p is either p*p+p+1 (or a divisor) or
p*p-1 (or a divisor). It is shown that the sequence has very good
autocorrelation and crosscorrelation properties which can be used in
cryptographic and key generation applications.
