Abstract [en]

It is possible to formulate several properties of a cipher that can be said to make the cipher homogeneous with respect to the key, i.e. whatever key used different aspects of the enciphering, deciphering and decrypting processes will be independent of the key choice. We investigate such properties and define a property called key homogeneity. The class of key homogeneous ciphers is shown to include the class of pure ciphers. The algebraic properties of pure ciphers are analyzed in detail. Finally the connection between pure ciphers and key homogeneous ciphers is investigated.
