| Abstract(in English) | Hash function is a function which maps input of arbitrary length into output fixed length. In this article, it states double block length hash function based blockcipher. There are three well-known methods, Weimar Davies-Meyer, Abreast Davies-Meyer, Hirose06. These methods are shown that its secrity is ideal. But, thier rate is all 1/2, where rate is index of efficiency of hash function. Their rate have been improved for 20 tears over. In this article, we propose hash function with high rate possible. The proposal method uses n-bit blockcipher with n-bit key length. After estimating of secrity, we discuss the proposal. |
