CLP-100: Hash Flow Through Core

The CLP-100 is part of Elliptic’s silicon-proven, high-quality, cost-effective IP portfolio, and can be tuned exactly to the functionality and performance level required by SoC designers or system integrators.

The CLP-100 Hash Flow-Through Core offers designers the ability to stream a message into the core directly from a MAC or other streaming interface and compute the cryptographic hash or digest which is then presented on the output FIFO. The core can be configured with one or more hash algorithms depending on the target application.

NIST has recently released a new draft specification, FIPS 180-4 Secure Hash Standard, intended to supersede FIPS 180-3. Two additional algorithms, SHA-512/224 and SHA-512/256, have been introduced to allow for more efficient implementation alternatives on platforms optimized for 64-bit operations. Elliptic's family of hardware and software solutions, including the CLP-100, fully support these new algorithms.
