We propose and analyze a new modification of the Hill cipher, HCM-EE, generating dynamic
encryption key matrix by exponentiation that is made efficiently with the help of eigenvalues.
Security of HCM-EE is provided by the use of a large number of dynamic keys. Experimental
results show that HCM-EE is from two to seven times more effective in the encryption quality
of RGB bitmap images than Hill cipher and its known modifications in the case of images
with large single colour areas, and slightly more effective otherwise. It is two times faster …

Security of HCM-EE is provided by the use of a large number of dynamic keys. Experimental results show that HCM-EE is from two to seven times more effective in the encryption quality of RGB bitmap images than Hill cipher and its known modifications in the case of images with large single colour areas, and slightly more effective otherwise. It is two times faster than HCM-H, having the best encryption quality among Hill cipher modifications compared versus HCM-EE.
