Isolated Proofs of Knowledge and Isolated Zero Knowledge
We introduce a new notion called -isolated proofs of knowledge ( -IPoK). These are proofs of knowledge where a cheating prover is allowed to exchange up to bits of communication wi...

Why One Should Also Secure RSA Public Key Elements
It is well known that a malicious adversary can try to retrieve secret information by inducing a fault during cryptographic operations. Following the work of Seifert on fault induc...

Efficient Concurrent Zero-Knowledge in the Auxiliary String Model
We show that if any one-way function exists, then 3-round concurrent zero-knowledge arguments for all NP problems can be built in a model where a short auxiliary string with a pres...

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...

Resettable Cryptography in Constant Rounds - The Case of Zero Knowledge
A fundamental question in cryptography deals with understanding the role that randomness plays in cryptographic protocols and to what extent it is necessary. One particular line o...
