Identity-based cryptography can greatly reduce the comple xity of sending encrypted messages over the Internet. However, it necessarily requires an entity known as a pr iv te-key generator (PKG), which can create private keys for users, and so can passively eavesdrop on all encrypt ed communications. Although a distributed privatekey generator has been suggested as a way to mitigate this pro blem, to date there have been no practical designs proposed for one. This paper presents the first… CONTINUE READING
