The Linux 7.4 kernel updates include optimized AES implementations for x86 and RISC-V, enhancing cryptographic performance.

Why it matters

These optimizations can lead to faster encryption and decryption processes, improving system security and performance.

The Linux kernel got faster ways to do something called AES encryption, which helps keep data safe. Now it can do it quicker on different kinds of computers.

Analysis

{"heading":"Optimized AES Implementations for x86 and RISC-V","subheading":"Linux 7.4 Crypto Library Updates","content":["The full list of crypto library updates for Linux 7.4 can be found in this pull request.","The updates include optimizations for x86/x86_64 and RISC-V architectures, as well as an optimized AES-XTS implementation for SPARC64."]}

Key points

  • Linux 7.4 kernel crypto library gains optimized AES implementations for x86 and RISC-V
  • Optimized AES implementations include ECB, CBC, CBC-CTS, CTR, XCTR, and XTS modes
  • Optimized implementations now use AVX optimized code and AES-NI instructions on x86_64 CPUs
  • Stian Halseth's optimized AES-XTS implementation for SPARC64 is now available
  • The full list of crypto library updates for Linux 7.4 can be found in this pull request
The Upside

These optimizations could make systems more secure and faster, especially for computers that use Intel or AMD chips.

The Downside

There might be some small issues with the new optimizations, but overall it should be a good thing for Linux.
