Abstract: Techniques are provided to create and manage groups of users. A group can be treated as a single entity. For privacy of a user, user keys can be translated to group keys, which are then used to access resources. The user can prove membership in the group via their keys (e.g., using a diversified public key), and then get the group keys in response, e.g., after verification to a group server using a diversified user key.
