But outsourcing sensitive data to an untrusted third party requires cryptographic methods like encryption. This paper presents a novel approach to a distributed cloud key management scheme. In a setting with a public cloud, data is encrypted by a trusted adapter before upload. The encryption key is not persistently stored at the adapter. Several entities share parts of the key that is computed and temporarily stored at the adapter if needed. This work describes how the key management is working during bootstrapping and runtime as well as how recovery is performed.
