wolfSSL has easy options for building and running without any malloc’s! Avoiding the use of all dynamic memory can be important in many environments, including safety critical ones and the use with satellites, being one of NASA’s 10 rules to not use any dynamic memory after initialization. The easy build options for no system malloc’s […]

Secure Boot and Glitching Attacks
In general, a “glitch” is a momentary fault that may happen on a system, preventing it from working properly, for a brief amount of time. The effects of a single glitch on proper software execution may be multiple, including catastrophic consequences that may prevent the system from continuing the execution. Glitching attacks are complex and […]

Read MoreMore TagwolfSSL Asynchronous Support
The wolfSSL / wolfCrypt libraries support asynchronous (non-blocking) crypto using external hardware acceleration with the Intel QuickAssist and Cavium Nitrox III/V adapters. These are PCIe devices that accelerate crypto operations. Use of the asynchronous hardware acceleration support significantly increases performance for server platforms requiring high connection rates and throughput. For some performance numbers see this […]

Secure shell and file access for embedded systems Unlike embedded Linux, or rich CPU-based systems, embedded systems running on a microcontroller rarely have support for file systems. Most often these devices run a firmware stored on a flash memory. However, more advanced microcontroller-based systems designed for edge computing offer the possibility to connect non-volatile storage […]
