HIDE: Hybrid symmetric key algorithm for integrity check, dynamic key generation and encryption

This paper proposes a hybrid encryption technique that generates a key dynamically, along with integrity check parameters. Our approach generates the key stream using a chained approach, beginning with an initial preshared key. Subsequent keys are derived using logical operations on intermediate cipher texts and intermediate keys generated in each stage. This is an improvement over chaining techniques, which use a cipher text to derive successive keys. We validate our algorithm by proof-of-concept implementation and security analysis.
