Cs. Laih et Mj. Gau, CRYPTANALYSIS OF A DIOPHANTINE EQUATION ORIENTED PUBLIC-KEY CRYPTOSYSTEM, I.E.E.E. transactions on computers, 46(4), 1997, pp. 511-512
Lin et al, proposed a new public-key cipher system whose security is b
ased upon the Diophantine equations. In this note, we show that their
scheme is insecure under the ciphertext only attack.
