Bounded Key-Dependent Message Security
We construct the first public-key encryption scheme that is proven secure (in the standard model, under standard assumptions) even when the attacker gets access to encryptions of ...

Shrinking the Keys of Discrete-Log-Type Lossy Trapdoor Functions
To this day, realizations in the standard-model of (lossy) trapdoor functions from discrete-log-type assumptions require large public key sizes, e.g., about Θ(λ2 ) group elements...

Fully Homomorphic Encryption from Ring-LWE and Security for Key Dependent Messages
We present a somewhat homomorphic encryption scheme that is both very simple to describe and analyze, and whose security (quantumly) reduces to the worst-case hardness of problems ...

Key Distribution in Mobile Ad Hoc Networks Based on Message Relaying
Abstract. Securing wireless mobile ad hoc networks (MANETs) is challenging due to the lack of centralized authority and poor connectivity. A key distribution mechanism is central t...

The Power of Proofs-of-Possession: Securing Multiparty Signatures against Rogue-Key Attacks
Abstract. Multiparty signature protocols need protection against roguekey attacks, made possible whenever an adversary can choose its public key(s) arbitrarily. For many schemes, p...
