Secure distribution infrastructure for hardware digital contents

摘要: Field-programmable gate array (FPGA) reconfigurability creates the possibility of distributing hardware cores pretty much like software digital contents, possibly on payment or a subscription basis. In this work, authors propose an infrastructure for secure distribution such contents (HDCs). Aimed at practical realisation envisioned scenario, study analyses security-related features current FPGA devices, example, (partial) bitstream encryption, and takes them as underlying constraints definition infrastructure. This work clearly identifies roles involved in process, including trusted third-party entity, introduces cryptographic protocol ensuring confidentiality trustworthiness partial bitstreams dynamically downloaded to user's device. also presents detailed case-study application namely image codec components, providing few quantitative results demonstrating limited overhead incurred by proposed solution terms time area costs. The conclusive section discusses lesson learned from draws proposals evolution which may enable full HDC concept.
