The Trusted Edge
share
Edge computing promises to reshape the centralized nature of today's cloud-based applications by bringing computing resources, at least in part, closer to the user. Reasons include the increasing need for real-time (short-delay, reliably-connected) computing and resource-demanding artificial intelligence (AI) algorithms that overstrain mobile devices' batteries or compute power but are too bandwidth-demanding to be offloaded to a distant cloud. However, companies may need to run their protected business logic on (untrusted) third-party edge devices, which can lead to serious issues due to weaker security measures than in cloud environments. This article makes the case for trusted edge computing (TEC), which focuses on developing concepts and methods for protecting application providers' business logic (and thus their intellectual property) specifically tailored to open edge infrastructures. This article further discusses open challenges in TEC to be addressed in the future. Otherwise, edge computing risks being a non-starter for most businesses due to the inadequate and neglected protection of intellectual property.
