Abstract: An encryption management system provides a solution for embedded system device authentication, secure server-to-device communications, and encryption key management. It reduces implementation times and costs associated with using cryptography for authentication and data privacy with embedded systems applications by freeing application developers from having to develop, manage, or update security-based features in their server-based applications. The template-based approach of the system provides highly customable and accessible security functionalities. To utilize services provided by the encryption management system in some embodiments, calling applications provide input parameters and function calls in the form of a template at runtime, and the output in the form of encrypted and secured messages are either sent to the client devices automatically or returned to the calling applications.
