| Abstract(in English) | We estimated and calculated values of the algebraic degree of the generalized PURE ciphers which round functions are defined as y=(x+_2K)^<2^t+1>. The algebraic degree of the generalized PURE ciphers is nearly proportion to the number of rounds. The proportionality constant increases as the exponent 2^t+1 increases. The algebraic degree of block ciphers is an important characteristic which is used to estimate the security against the higher order differential attack. However the generalized PURE ciphers are well known as to be provable secure against the differential and linear cryptanalysis but judging from the obtained results of the algebraic degree, the generalized PURE ciphers are not so strong to the higher order differential attack. |
