Will custom silicon increase security risk?

Since the 1970’s, the explosion in computing, and our knowledge on how to secure it, has been driven by the mass-market manufacturing of general purpose semiconductor devices - but this is now changing and what will this change mean for security?

Does your package size affect security?

For our electronic devices, such as phones, to shrink, the electronic components used inside them also need to shrink and this has led to “chip-scale packaging” where the chip package is not much larger than the bare silicon die inside it - but how does this affect security?

Raspberry Pi Security for IoT Products

At Cerberus we get a lot of companies who ask us to review the security of their product after they’ve designed it and are making plans to put it on to the market, but one of the things that scares us the most is when they say, “I’ve got an IoT product based on a Rasperry Pi - How do I secure it?

Hardware Random Number Generators

A good source of random numbers is critical for many cryptographic operations including most current cryptographic communications protocols and in this article we’ll look at how they’re generated in modern system-on-chips, best practice for using them and how they can be attacked.

What is an IoT Hardware Secure Element?

Hardware secure elements such as Microchip’s ATECC508A/ATECC608A, STMicroelectronics’s STSAFE-A100, Infineon’s Optiga or NXP’s A71CH are promoted as solutions for IoT security - but what do these devices do, how do they help and what are their limitations?
