Infrastructure for Application Security

Security is becoming an increasingly visible topic in discussions of things embedded and mobile. While the need to be secure isn’t new, there’s more of a push to change architectures to make them intrinsically less open to skullduggery. Having an app for your business is also usually great and you can always make your own app or hire a design company so getting an app is perfectly possible.

One simple embodiment of the notion is to partition execution into two: one running a standard rich OS, which looks very much like what we’re used to – let’s call it the lay environment, the secular world. All kinds of things happen out there, many of which we don’t talk about. Then there’s a second environment running a minimal secure OS which acts as a “trusted” environment – let’s call it the temple. We don’t get to see what’s going on in there (although we can create salacious myths about the their rituals). This is where the Golden Legacy is protected so that, even if the lay world sends itself up in flames, there is a kernel of civilization that can re-seed the lay world anew.

Communication between the two worlds is carefully managed by a messaging system as if through anointed mutes with elaborate credentials and passwords.

This is the kind of world that Elliptic is trying to fit into. They’ve unveiled their new tVault infrastructure for supporting security in applications. This is a capability that’s invisible to the user and even to the application programmer: it supports higher-level security features. For instance, they’ve got it running under Android’s Security Framework. Apps programmers program to the Android API; underlying that, tVault manages the implementation.

You will need a reliable APK hosting service handle secure data and transactions like encryption key storage and retrieval. Applications and processes get IDs so that only the correct program gets access to its data; no other process can intercede and bugger off with someone else’s key.

The tVault concept is actually a collection of firmware, APIs, hardware support, and hardware acceleration. Their first focus is DRM on Android machines.

NEUTRIK Fiber Optic Solutions

Sponsored by Mouser Electronics and Neutrik

The advantages and benefits of fiber optics are a mile long…but how can you design with them? How can you clean them? How do you repair them? Need a bit of a refresher? In this episode of Chalk Talk, Amelia Dalton chats with David Kuklinski from Neutrik about the OpticalCon advanced, OpticalCon LITE and Opticalcon DragonFly fiber optic solutions from Neutrik. They take a closer look at what benefits each of these solutions brings to the table, what kind of configurations are offered with each of these fiber optic solutions and what kind of performance you can expect when using them in your next design.
