Abstract
For original paper see ibid., vol. 40, no. 10, pp. 660-6 (1993). A proposal for using a chaotic system with finite wordlength as a means for encrypting data is criticized on the grounds that some of the proposed schemes are readily attacked in the "chosen plaintext" scenario. Moreover, the proposed schemes do not appear to have any advantages over more conventional cryptographic methods as far as security is concerned.
