The Linux kernel has a rich and modular cryptographic API that is used extensively by familiar user facing software such as Android. It's also cryptic, badly documented, subject to change and can easily bite you in unexpected and painful ways.
This talk will describe the crypto API, provide some usage example and discuss some of the more interesting in-kernel users, such as DM-Crypt, DM-Verity and the new fie system encryption code.
Gilad Ben-Yossef is a principal software engineer at ARM. He works on the kernel security sub-system and the ARM CryptCell engine. Open source work done by Gilad includes an experiment in integration of network processors in the networking stack, a patch set for reducing the interference caused to user space processes in large multi-core systems by Linux kernel “maintenance” work and on SMP support for the Synopsys Arc processor among others.
Gilad has co-authored O’Reilly’s “Building Embedded Linux Systems” 2nd edition and presented at such venues as Embedded Linux Conference Europe and the Ottawa Linux Symposium, as well as co-founded Hamakor, an Israeli NGO for the advancement for Open Source and Free Software in Israel. When not hacking on kernel code you can find Gilad meditating and making dad jokes on Twitter.
