• Majorly worked on below areas:
• I designed and developed the secure boot and corresponding changes in our loader as well as suggested few correction in OTP boot sequence which was part of chip vendor
• like Broadcom, Mstar, Telechip (ongoing). -
• TEE –Implemented TA application and client communication. Defined spec for client API interface for SVP.
• Designed and implemented secure boot and secure boot firmware upgrade which is called BSECK in Broadcom design. This is to upgrade firmware which is traditionally locked and non upgradable once comes out of factory. with this mechanism we can still upgrade in field. This will also increase life and product endurance enhanced drastically without compromising security.
• DRM design for widevine using VGDRM component used OEMCrypto License and content related operations such as sign/verify license and different type of key handling.
• SVP specification definition for 4k content based on different security requirement defined by media labs, first using Broadcom SAGE processor.
• TEE-TA implementation for VG DRM , This is POC along with Spec finalization, related to mode and restriction on TA. Who can call TA and security requirement defined by Netflix and media labs.
• Good Understand of TEE TA architecture and different areas of Specification by GPD including Network component.
• Understand thoroughly SVP recommendation and specification.
• In past implemented RCU, FP-Segment display and NAND/Nor drivers in Linux.
• As part of Driver team, fixed M2M,CM device related bug.
• OTT profile bring with CISCO middleware with ST platform(palma).
• First 4K TATA sky full s/w stack bring.
• Designed and developed IP(Hybrid) loader which support IPMC,TFTP,Sat.
• Worked on LHCR approval and KRFS for kernel hardening.
• Good understanding of Linux internals and OS.
• Silicon level Dhyrostone(core-Mark) and stack and memory leak profilling.
• Broadcom Android TV Debugged some of HAL layer related to rcu keys ,Binder architecture.
