Provably Secure Timed-Release Public Key Encryption
May 2008
A timed-release cryptosystem allows a sender to encrypt a message so that only the intended recipient can read it only after a specified time. The authors formalize the concept of a secure...

Proposal of a New Efficient Public Key System for Encryption and Digital Signatures
Oct 2007
In this paper a new efficient public key cryptosystem usable for both encryption and digital signatures is presented. Due to its simple structure this public key cipher can be implemented easily...

Joint State Theorems for Public-Key Encryption and Digital Signature Functionalities With Local Computation
Apr 2008
Composition theorems in simulation-based approaches allow building complex protocols from sub-protocols in a modular way. However, as first pointed out and studied by Canetti and Rabin, this...

Authenticated Broadcast With a Partially Compromised Public-Key Infrastructure
Aug 2009
Given a Public-Key Infrastructure (PKI) and digital signatures, it is possible to construct broadcast protocols tolerating any number of corrupted parties. Almost all existing protocols, however,...

On Notions of Security for Deterministic Encryption, and Efficient Constructions Without Random Oracles
Feb 2009
The study of deterministic public-key encryption was initiated by Bellare et al. (CRYPTO '07), who provided the "Strongest Possible" notion of security for this primitive (called PRIV) and...

Identity-Based Encryption With Efficient Revocation
Oct 2008
Identity-Based Encryption (IBE) is an exciting alternative to public-key encryption, as IBE eliminates the need for a Public Key Infrastructure (PKI). Any setting, PKI- or identity-based, must...
