Linux Kernel Crypto API Herbert Xu Red Hat Inc.
Current State ● Async + sync cipher interface. ● Async + sync hash interface. ● AEAD interface. ● Compress-as-you-go interface. ● RNG interface.
Current State ● A handful of async PCI drivers. ● Support for on-chip acceleration. ● AEAD algorithms: CCM/GCM. ● Disk encryption algorithms. ● Mandatory self-test.
Generic Algorithms ● DMA offload similar to crypto offload. ● Reduce impact on generic code (e.g., TCP). ● New algorithms: – memcpy: Similar to ciphers. – xor: Binary operation.
User-space API ● Why: – Hardware management. – Certification. ● How: – Type-agnostic. – IOV-based interface.
Misc ● New algorithms: – Hashes. – Stream ciphers. ● User-space control interface.
