Moving Uptown to Umode

pmode[1] partitions may be just as effective as umode[2] partitions for reliability; however, umode partitions are much better for security for the following reasons: The hardware enforced pmode barrier prevents umode access to pmode data and code.The MPU cannot be turned off nor altered from umode.The Background Region (BR) is ineffective in umode. These combine … Continue reading Moving Uptown to Umode

FreeRTOS Security? Not To Worry

It is now possible to greatly increase the security of FreeRTOS projects by porting them to SecureSMX®, using FRPort™. SecureSMX facilitates partitioning an application into isolated partitions. This provides strong protection against hacking since a hacker can only access code and data within the partition that he has entered. In this solution paper, we discuss … Continue reading FreeRTOS Security? Not To Worry

Is Your Thing In Danger?

Introduction The figure below shows the security structure of typical microcontroller embedded software. There is no structure! A hacker who has gained access to the system, has access to anything he wants, including keys and other secrets. This undermines the security afforded by encryption, authentication, and other security methods employed in modern systems. This figure … Continue reading Is Your Thing In Danger?
