Abstract
Techniques for establishing mutual authentication of software layers of an application are described. During initialization of the application, the software layers execute a binding algorithm to exchange secrets to bind the software layers to one another. During subsequent runtime of the software application, the software layers execute a runtime key derivation algorithm to combine the secrets shared during initialization with dynamic time information to generate a data encryption key. The software layers can then securely transfer data with each other by encrypting and decrypting data exchanged between the software layers using the dynamically generated data encryption key.
