Abstract

The invention relates to a method of key management for group-based controlled access to encrypted data, in which a decryption key for the encrypted data can be obtained by a party if the party is a member of at least one group which is authorized to access the data, the groups being organized in a hierarchical tree in which each non-leaf node represents a group and each leaf node represents a member of all groups represented by nodes hierarchically superior to the leaf node in question.
