Testing the performance of the improved Rubik´s cube encryption algorithm on virtual systems

Securing image content through encryption is sometimes necessary is sensitive data is monitored. The improved Rubik´s cube encryption algorithm is a simple yet powerful solution that uses simple functions (such as shuffling, XOR operations with rows and columns and matrix transposition) that operate on a pixel matrix array. The algorithm runs on both the client (performing the encryption) and the server (performing the decryption) communicating through a computer network. The clients are various systems ranging from mobile to desktop systems. The servers where the tests were made were virtualized machines. This paper implements the improved Rubik´s cube encryption algorithm in Java and tests its performance on servers running two bare metal hypervisors: VMware ESXi and Microsoft Hyper-V. The performance of the implementation is also compared with the implementation of the original Rubik´s cube encryption algorithm.
