AES Keywrap Core
Overview
This core extends the Algotronix G3 Advanced Encryption Standard (AES) core by providing a secure, standardized method for loading cryptographic keys into the encryption unit. The AES-G3 core is included within this product.
The AES Keywrap algorithm was developed by National Institute of Standards and Technology (NIST) and was adopted by the Internet Engineering Task Force (IETF) as RFC 3394. Use of the AES Keywrap algorithm is also specified in the W3C XML Security Specification and in the IEEE draft standard for encryption of data on hard disks (IEEE P1619). In order to meet specifications such as FIPS140-2 level 2 and higher or the equivalent Common Criteria Protection Profiles protection must be provided for Critical Security Parameters (CSPs) such as cryptographic keys entering the encryption unit. The Key-Wrap algorithm provides an approved mechanism for cryptographically protecting CSPs as they enter the security module.
