10341: Data Protection in Linux With IBM Z and LinuxONE Crypto Hardware

Project and Program: Core Platform, Linux

Tags: Proceedings, SHARE Orlando 2024, 2024

Whenever data leaves a system be it as a message to an external receiver or when stored on a storage subsystem it requires special protection as the access control mechanisms provided by the operating system no longer apply. Cryptography is the method of choice to protect data in-flight and at-rest. In this presentation, we give an overview of the crypto hardware available with IBM Z and LinuxONE systems and describe how they can be used in Linux to accelerate secure communication, encrypt complete volumes (block devices) and how to manage and protect the cryptographic key used for encryption and digital signatures. The presentation will describe how cryptographic HW can be configured, and which libraries can be used to (implicitly) benefit from the cryptographic hardware. -- Presented by Reinhard Buendgen
