Experience

1. Senior Software Engineer
   Solaris Security Engineering Group, Oracle America, Inc.

   August 2014 – Present
   Santa Clara, CA
   • Developed Verified Boot for Kernel Zones and LDoms (Oracle VM Server for SPARC) on Solaris in C to detect accidental or malicious modification of a kernel module before loading and executing it by checking the factory-signed signature in it.
   • Designed and developed audit of Solaris Verified Boot events in C to generate audit trails when inappropriately-signed kernel modules are to be loaded.
   • Integrated key components for multi-factor authentication such as OpenCA Research Labs' OCSP Responder and LibPKI into Solaris.
   • Developed a prototype TPM 2.0 driver for Solaris in C to eliminate dependencies on obsolete cryptography algorithms such as SHA-1 used in TPM 1.2 standard.
2. Research Assistant
