Enhancing Cloud and Mist Computing Security Using Quantum Color-Based Hybrid Encryption with RSA Mapping

transmission and in-storage has become a paramount concern. Classical encryption techniques are becoming increasingly vulnerable from quantum computing, sophisticated cyber threats, and other future security vulnerabilities, we’ve developed a new method of hybrid encryption called Quantum Color-Based Key Distribution (QCKD) with RSA Mapping to protect data and, therefore, secure data transmission using QCKD with RSA Mapping. Our approach is based on the encoding of encryption keys with specific photons colors and we’ve introduced these dummy colors as an additional security mechanism to confuse the potential eavesdropper. The color-to-key mapping will be encrypted and shared using RSA public-key cryptography and should remain protected so eavesdroppers cannot decipher the color sequence. At the end of the key establishment steps, the standard derived session key will be used to perform conventional symmetric encryption (AES-256) to protect the data. The overall approach allows us to combine the theoretical security of quantum encryption with practical hybrid cryptography, which includes protecting data when deployed in cloud or mist computing systems.
