The Key Authority - Secure Key Management in Hierarchical Public Key Infrastructures
We model a private key's life cycle as a finite state machine. The states are the key's phases of life and the transition functions describe tasks to be done with the key...

Efficient Intrusion-Resilient Signatures Without Random Oracles
Intrusion-resilient signatures are key-evolving protocols that extend the concepts of forward-secure and key-insulated signatures. As in the latter schemes, time is divided into di...

Attribute-based encryption for fine-grained access control of encrypted data
As more sensitive data is shared and stored by third-party sites on the Internet, there will be a need to encrypt data stored at these sites. One drawback of encrypting data, is t...
