Creating Encrypted Data Partitions Using the Yocto meta-toradex-security Layer

Introduction In the previous article, we introduced how to create a separate partition using the meta-toradex-security layer. Next, we will explain how to use encryption features on that partition, perform read and write performance tests, and if you are still interested, the final section will elaborate on the principles behind partition encryption. The technical implementation … Read more
