Abstract
Rekeying an Information Handling System (IHS) network End-to-End Efficient Encryption (E2EEE) with security chaining includes locking an encrypted data volume, preventing reading of, and writing to, the encrypted data volume by applications. A data source IHS may request a new key from a key management system and write new metadata in a trailer of the encrypted data block using a different key slot than a currently used and active metadata key slot, wherein the different key slot is updated with the with the new key. The data source IHS then sends an out-of-data signal to change the use key slot from the currently used key slot to the different key slot. Thereafter, the data source IHS unlocks the encrypted data volume, enabling writing and/or reading user data by the data source IHS and encryption and decryption in all IHS E2EEE data connection segment interfaces.
