The application of block ciphers in the modern society is enormous. One branch of this development is getting a new dimension - the application of quasigroups and quasigroup transformations in the block ciphers. This paper contains the results of the research involving the family of block ciphers named SQBC (Small Quasigroup Block Cipher), which is based on quasigroups and quasigroup transformations. Actually, we will discuss the results of encrypting images in different formats using the SQBC block cipher based on quasigroups of order 4.
