We designed a secure key registration system based on the proactive secret-sharing scheme. A user can register important data such as a session key to a distributed system in a (t...
Distributed key generation is a main component of threshold cryptosystems and distributed cryptographic computing in general. Solutions to the distributed generation of private key...

Distributed key generation is one of the most challenging tasks for threshold cryptosystems. Designing such a protocol and proving its security against a malicious, adaptive adver...
An identity-based encryption (IBE) scheme can greatly reduce the complexity of sending encrypted messages. However, an IBE scheme necessarily requires a private-key generator (PKG)...
Generating a distributed key, where a constant fraction of the players can reconstruct the key, is an essential component of many largescale distributed computing tasks such as ful...
