Hydra is a scaleable decentralised architecture to create and distribute symmetric cryptographic keys to large multicast-based groups. The group is divided into a number of TTL-scoped regions in order to achieve flexible and efficient key management, particularly in face of group membership changes. Hydra does not employ a manager for subgroup managers, and hence, it is not vulnerable to failures of single entities.
