Every hardware cryptography scheme wolfSSL has ever enabled

At wolfSSL we support hardware cryptography for a wide range of platforms. The benefits of hardware cryptography include reduced code footprint size, improved security, acceleration of cryptographic operations, and utilization of true random number generators. For example, this allows everything from wolfBoot to TLS cipher suites to enjoy acceleration of cryptographic operations. Furthermore, we have […]

TLS Glitch Resistance on Encrypt

We’ve had some recent interest in adding resistance for detection of encrypt issues due to glitching. A recent report for ESP32 AES HW showed it was possible to skip the encrypt operation with some timed glitching. The attack requires physical access to the hardware. The attack results in the HW encrypt operation being skipped and […]
