Abstract
In this paper we review quaternion encryption methods for multimedia transmission. We explain their weak and strong properties as well as suggest possible modifications. Our main focus is an algorithm QFC presented in paper by Dzwonkowski et al. (2015). All encryption methods, presented in this paper, use special properties of quaternions to perform rotations of data sequences in 3D space. Each method uses a common key generation algorithm (to form an infinite key space), as well as a modular arithmetic for operations with quaternions. A computer-based analysis has been carried out for all encryption methods. The obtained results are discussed at the end of this paper.
