The classical Kharitonov theorem on interval stability cannot be carried over from polynomials to arbitrary entire functions In this paper we identify a class of entire functions for which the desired generalization of the Kharitonov theorem can be Gottlieb Vadim Kotlyar and Abraham Nudelman Department of Chemistry BarIlan University RamatGan 52900 Israel Received June 27 1997 In the course of the routine use of NMR as an aid for organicchemistryadaytodayproblemistheidentifica tion of signals In this paper we examine algebraic attacks on the Advanced Encryption Standard AES also known as Rijndael We begin with a brief review of the history of AES followed by a description of the AES algorithm We then discuss the problem of solving system Alice Bob insecure hannel Ev ea esdropp er brPage 3br cryptosystem or cipher is pro cedure to render messages unin telligible except to the authorized or in tended recipien t Alice plain text Encrypt Bob Decrypt original text Ev ciphertext secure ha M.

Known plaintext attack. The cryptanalyst has a set of plaintexts and the corresponding ciphertexts. r and r = occurs in multiple test cases, there may be some wasted effort but testing soundness is not af-fected.
