IBM Hyper Protect Offline Signing Orchestrator

IBM® Hyper Protect Offline Signing Orchestrator (Offline Signing Orchestrator or OSO for short) is a cold storage solution on IBM LinuxONE and Linux on Z, which brokers communications between two different applications that are designed not to communicate directly. Due to the level of isolation between applications there is no network connection which eliminates the network attack vector. OSO leverages encrypted in-memory communication that is unidirectional and is based on IBM HiperSockets.
