The design and security of block ciphers, together with their application in hashing techniques, are considered. In particular, iterated block ciphers that are based on iterating a weak round function several times are considered. Four basic constructions for the round function of an iterated cipher are studied. The iterated block cipher IDEA is proposed. This cipher is based on the new design concept of mixing different group operations on 16-bit subblocks. Using operations on subblocks facilitates the software implementation of the cipher. The regular structure of the cipher facilitates hardware implementation. The interaction of the three chosen \"incompatible\" group operations provides the necessary \"confusion\", and the chosen cipher structure causes the required \"diffusion\". ....","brand":"Hartung-Gorre","offers":[{"title":"Default Title","offer_id":53737760850262,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0925\/5829\/5382\/files\/product_image_9783891915738_1.jpg?v=1781783075","url":"https:\/\/www.momoxbooks.com\/products\/lai-xueija-on-the-design-and-security-of-block-ciphers-9783891915738","provider":"momoxbooks","version":"1.0","type":"link"}
