How to migrate 3DES keys from a FIPS to a non-FIPS AWS CloudHSM cluster
Security Blog
This article provides guidance on securely migrating Triple Data Encryption Standard (3DES) keys from a FIPS-compliant AWS CloudHSM cluster to a non-FIPS cluster using the new hsm2 instance type.
Specifically, the article covers:
- Background on AWS CloudHSM and the withdrawal of 3DES as a FIPS-approved encryption algorithm
- An overview of the solution to migrate keys using an RSA-AES wrap mechanism without exposing plaintext keys
- Important considerations when migrating keys, such as key ownership, key attributes, and backup retention
- Step-by-step instructions to generate an RSA key pair, export the public key, import it to the source cluster, wrap keys using the public key, move the wrapped keys, and unwrap them in the target cluster using the private key
- Testing approach to verify successful migration of 3DES keys
