Abstract
Enabling End-to-End Efficient Encryption (E2EEE) with security chaining in an Information Handling System (IHS) network includes: a data source IHS writing metadata containing a key slot, in a trailer of a data block and sending an out-of-band signal to use the key slot; an IHS security chaining logic regenerates the signal to each next IHS E2EEE data connection segment interface; and an encryption configuration state machine of each interface setting a use slot and an active slot to the key slot, in response to the signal. Disabling E2EEE with security chaining includes: the data source IHS sending an out-of-band signal to not use a key slot; the IHS security chaining logic regenerating the signal to each next interface; and the state machine of each interface changing the state machine state to not use a key slot and to not set an active key slot, in response to the signal.
