Zusammenfassung:The present invention relates to a hybrid cryptosystem using linear transformation and byte substitution to enhance the data security. The data secrecy protects the data from unauthorized access. The cryptographic mechanism provides confidentiality by encrypting data. The hybrid cryptographic symmetric key model is linear transformation based cryptosystem using sub key groups and byte substitution. This is secure and efficient as the key size is reduced from n x n to n. As the time complexity of the invention reduced from cubic to quadratic, throughput of the proposed invention is high.
