Distributed key generation

From Wikipedia, the free encyclopedia

For some protocols no party should be in the sole possession of the secret key. Rather, during distributed key generation every party obtains a share of the key. A threshold of the participating parties need to cooperate in order to achieve a cryptographic task, such as decrypting a message.

In this sense distributed key generation is a logical preliminary step for doing threshold decryption without need for a trusted third party
