摘要：
The present invention provides a system (100) for storing encrypted data. The system (100) comprises a server (101) and a plurality of clients (102). A first client (102a) of the plurality of clients (102) is configured to send to the server (101) a first reference value (103) calculated from data to be encrypted and stored. The server (101) is configured to determine a group (104) of second clients (102b) from the plurality of clients (102), the second clients (102b) having each sent to the server (101) data with a second reference value equal to the first reference value (103). The group (104) of second clients (102b) is configured to perform a passive key exchange protocol (105) with the first client (102a), and the server (101) is configured to determine, based on a result of the passive key exchange protocol (105), whether the data is to be stored in full or as deduplicated data.
