Systems and methods that may be used to provide multitenant key derivation and management using a unique protocol in which key derivation may be executed between the server that holds the root key and a client that holds the derivation data and obtains an encryption key. In one or more embodiments, the derivation data may be hashed. The disclosed protocol ensures that the server does not get access to or learn anything about the client's derived key, while the client does not get access to or learn anything about the server's root key.

System and method for multitenant key derivation

Aspects of the present disclosure provide techniques for encrypted data management. Embodiments include determining an encrypted data item in a data store that is related to a request from a data consuming user. Embodiments include determining a data owning user and an encryption key that correspond to the encrypted data item based on a key identifier associated with the encrypted data item. Embodiments include determining one or more additional encrypted data items and one or more additional encryption keys that correspond to the data owning user based on key identifiers associated with the one or more additional encrypted data items. Embodiments include generating a single data access ticket comprising information about the data consuming user, the data owning user, the encryption key, and the one or more additional encryption keys.
