Title: Mitchel B Butler: Innovator in Small Footprint Device Security
Introduction
Mitchel B Butler is a notable inventor based in Sunnyvale, CA, with a focus on enhancing security in small footprint devices. He holds a total of 9 patents, showcasing his contributions to the field of technology and security.
Latest Patents
Among his latest patents, Butler has developed techniques for permitting access across a context barrier on a small footprint device using an entry point object. This innovation allows a small footprint device to securely run multiple programs from unrelated vendors by incorporating a context barrier that isolates the execution of these programs. The context barrier performs essential security checks to ensure that both the principal and object are within the same namespace or memory space, verifying that a requested action is appropriate for the object being operated upon. Each program or set of programs operates in a separate context, and access across the context barrier can be controlled through the use of an entry point object. This object can either perform accesses on behalf of a requesting program or pass the request to the program to be accessed, effectively switching contexts as needed.
Another significant patent involves techniques for implementing security on a small footprint device using a context barrier. Similar to his previous work, this patent emphasizes the importance of security checks and the isolation of program execution, ensuring that multiple programs can run securely on devices such as smart cards.
