Gao's Chaos Cryptosystem Algorithim

P(i) Plaintext,C(i) Ciphertext,K(j) Key,Ch(i) Chaos signal, L Irrational number P(),C()-->Manage in byte,Length supposing that n byte. K()-->Character line from ASCII CODE,Length supposing that m. Ch(n) begin Xn+1=aXn(1.0-Xn) return Xn+1 end f(K) begin w = Sigmaj strtoul(K(j))j delay=int(w/L) return(double)(w/L-delay) end 1.K input 2.delay generato 3.Ch(i) generato 4.P(i) acquire 5.C(i)=P(i) XOR Ch(i+delay) 6.C(i) output ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com
