The method includes deriving, for each authorized client Cj, a first key KCj and a second key KTj, providing the client Cj with the first key KCj, and providing a Trusted Third Party (TTP) with the second key KTj. The method further includes, at a Policy Enforcement Point, receiving a request for performing the operation on the data storage from a client Ck of the authorized clients, acquiring a first key KCk from the client Ck, acquiring a second key KTk from the TTP, deriving the key KD from the first key KCk and the second key KTk, and performing the operation on the data storage using the derived key KD. The disclosed trust model uses two-part secret sharing."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Performing an operation on a data storage","description":"A method of performing an operation on a data storage for storing data being encrypted with a key KD associated with an owner of the data is provided.
