Shared control systems protect highly sensitive information by distributing its contents amongst a number of network entities, allowing the information to be generated only if certain predetermined subsets of these entities co-operate. Shared control systems form an essential information security primitive that is used, for example, to protect high level cryptographic master keys, to facilitate sensitive access control and to increase fault tolerance in distributed networks. They find use in any situation where trusting a single entity to conduct an operation is regarded as insecure or unreliable. In general the establishment of a shared control system involves the existence of a trusted organisation and its setting up of secure distribution channels with all participating entities. This is costly, but necessary, in order to launch the system. However, the environment within which the shared control system is operating may change during the lifetime of the system (entities may leave, entities may join, or the security of the system may need to be strengthened, or even weakened). In this case there is usually no option other than to re-initialise by effectively establishing an entirely new system. This is costly, and in certain circumstances may not even be possible. This project intends to investigate solutions to the problem of enabling dynamic changes to a shared control system that are more efficient and considerably less expensive than establishing a new system, thus benefitting all users, designers and operators of information security solutions that utilise shared control procedures.
