Boost MCU security AND performance with hardware accelerated crypto

In this Product How-To article, TI’s Carlos Betancourt and Greg Turner describe how the hardware accelerated cryptography modules built in to the company’s ARM-based Sitara processor family can be used to accelerate compute-intensive cryptographic algorithms and offload those tasks from the ARM core which can then devote the additional headroom to performance of real-time deterministic control functions. In 2010, …

Cryptography in software or hardware: It depends on the need

Cryptographic algorithms are high-performance, secure engines that require considerable space in a design. When countermeasures are added to thwart security attacks, the space and memory requirements grow even more demanding. For these reasons, cryptographic algorithms have traditionally been embedded as proprietary designs (i.e., intellectual property, IP) in hardware on smart cards or 8-bit chips. With recent improvements in core …
