Open Standards and Performance in Security

Use Intel® Cryptography Primitives Library to improve the performance of cryptographic operations in multimedia, enterprise data, embedded, communications, and scientific and technical applications.

This common cross-platform and cross-operating system API for routines is commonly used for cryptographic operations:

  • Security (constant-time running for secret processing functions)
  • Designed for the small footprint size
  • Optimized for Intel CPUs and instruction set architectures including hardware cryptography instructions
  • Configurable CPU dispatching for the best performance
  • Kernel mode compatibility
  • Thread-safe design
  • Data protection in the post-quantum era
  • FIPS 140 compliance 

What's New

  • Intel® Integrated Performance Primitives Cryptography (Intel® IPP Cryptography) is now Intel Cryptography Primitives Library
  • Experience the power of dispatching on an Intel® Xeon® 6 processor, turbocharging RSA encryption (2K, 3K, 4K) with multi-buffer capabilities.
  • Explore the future of hashing with our enhanced SM3 algorithm, now 5x faster thanks to the SM3 instruction.
  • Enhanced data protection in a post-quantum era with a new Intel-optimized LMS post-quantum crypto algorithm.
  • Advanced AES-GCM performance on Intel Xeon 6 processors and Intel® Core™ Ultra mobile and desktop processors with simplified integration and new code samples.

 

Optimizations

The Intel Cryptography Primitives Library applies:

  • Hardware cryptography instructions (AES-NI, SHA extensions) to accelerate cryptographic operations, improving performance and efficiency
  • Multi-buffer processing allowing for parallel processing of multiple data buffers, enhancing throughput
  • CPU dispatching to ensure the best available optimizations are used based on CPU capabilities of different Intel® processors
  • Algorithmic optimizations:
    • Karatsuba multiplication algorithm
    • Montgomery modular multiplication scheme
    • Precomputed value tables of values
    • Folding approach for multiply-reduce routines.

And more.

This ensures you are always at the forefront of cryptographic performance.

Security and Privacy

Both security and privacy are important in the physical and digital worlds. Privacy is the right to control how your information is viewed and used, while security is protection against threats or danger.

Security Starts with Intel

Federal Information Processing Standards (FIPS)

FIPS is developed and managed by the National Institute of Standards and Technology (NIST) and the Canadian Communications Security Establishment (CSE). ​
