T-IBE-T: Identity-Based Encryption for Inter-Tile Communication

Abstract

T-IBE-T applies identity-based encryption (IBE) to inter-tile communication in tiled multi-processor system-on-chip (MPSoC) hardware architectures. There, a network-on-chip (NoC) enables communication among topologically disconnected parts of an application. When such an MPSoC is shared while tiles are exclusively allocated, with malicious applications present, the NoC becomes a weak point. Yet minimal memory footprint, as well as scalability, are necessary preconditions on any security mechanism in this scenario. We show that T-IBE-T provides each component such as the tiles' OS instances, applications and tile application instances with a secure key exchange while ensuring asynchronicity, minimal latency and providing no-cost key distribution.
