Abstract: In one embodiment, an illustrative method herein may comprise: determining, by a device of a communication session, that a new epoch has occurred within the communication session, wherein the communication session has one or more member devices; generating, by the device and in response to the new epoch, a new key encryption key and a key bundle comprising one or more keys to decrypt content of the communication session from one or more previous epochs of the communication session; encrypting, by the device, the key bundle with the new key encryption key to create an encrypted key bundle; and sharing, from the device, the encrypted key bundle with the one or more member devices to allow the one or more member devices to access the content of the communication session from the one or more previous epochs.

Abstract: A connector coupling that comprises a connector body, a first collar that receives the connector body, and second collar that surrounds the first collar. A movable ratchet ring is supported by the connector body and includes at least one locking member. The movable ratchet ring is axially movable with respect to the first collar between engaged and disengaged positions. A stationary ratchet ring is coupled to the first collar and includes at least one locking member. When the movable ratchet ring is in the engaged position, the locking members of the rings are engaged, and rotating the second collar from the first position to the second position with respect to the first collar moves the movable ratchet ring to the disengaged position away from the stationary ratchet ring such that the locking members are disengaged, thereby allowing rotation of the first collar with respect to the connector body.
