CLP-45: Configurable Look Aside AES Core

The CLP-45: Configurable AES Core is a security engine that supports the Advanced Encryption Standard (AES) which is in widespread use in standards such as 802.11i, LTE-Advanced, WiMAX, SSL/TLS/DTLS, IPsec SRTP, Suite B and many other applications. This diversity of applications generates different performance requirements, modes of operation and key size selection for each target application.

The CLP-45 is highly configurable and it allows designers to select a core that is optimized for their target requirements in both features and gate count. The core is proven in multiple tape-outs ranging down to 40 nm and is fully verified under the NIST CAVP (Crypto Algorithm Validation Program).

  • Features cipher based message authentication counters
    • CMAC (compliant with NIST Special Publication SP 800-38b
    • XCBC (1 key variant as described in RFC 3566)
    • XCBC (3 key variant as proposed by Rogaway and Black)
  • Multiple performance options to tune throughput versus gate count:
    • Internal data path width
    • S-box technology
  • Options for any or all of 128, 192 and 256 bit keys
  • Configurable context memory to optimize area versus performance trade-offs
  • Hardware key expander
  • Key memory accessible through a separate memory interface
  • Test bench and synthesis scripts provided
