Authentication cores

Helion IP Core Products - Authentication cores

These are the hashing algorithms typically used to provide data integrity checking and authentication functions in secure protocols such as IPsec and SSL, and one-way data compression for digital signature applications. These solutions are suitable for ordinary hashing applications but may also provide the underlying hash function for keyed HMAC applications. These versatile building blocks developed by Helion represent some of the fastest and most efficient solutions available in the industry. Please follow the links below for further information.....

SHA-1 cores The original FIPS 180-1 approved secure hashing algorithm, widely used in Digital Signature and HMAC applications where data integrity and/or authentication are required. Available in ASIC and FPGA optimised versions.

SHA-256 cores The very latest FIPS 180-2 approved 32-bit secure hashing algorithm specifically designed to be used in conjunction with AES encryption using a 128-bit key. Typically used in Digital Signature and HMAC applications where data integrity and/or authentication are required. Available in ASIC and FPGA optimised versions.

SHA-384/512 cores The very latest FIPS 180-2 approved 64-bit secure hashing algorithms specifically designed to be used in conjunction with AES encryption technology using 192- and 256-bit keys. Typically used in Digital Signature and HMAC applications where data integrity and/or authentication are required. Available in ASIC and FPGA optimised versions.

MD5 cores The classic industry-standard secure hashing algorithm, still used to provide authentication in keyed HMAC applications. Available in ASIC and FPGA optimised versions.

Multi-mode SHA-1/SHA-2/MD5 cores Bringing together into a single core, support for multiple industry standard secure hashing algorithms. These are perfect when support is required for a suite of algorithms, in such applications like IPsec or SSL. Available in ASIC and FPGA optimised versions.

AES based authentication (XCBC, OMAC) cores Based on AES encryption, these authentication modes offer a modern alternative to more traditional hashing functions. As used in IPsec, and available in ASIC and FPGA optimised versions.
