Adaptively Secure Feldman VSS and Applications to Universally-Composable Threshold Cryptography
We propose the first distributed discrete-log key generation (DLKG) protocol from scratch which is adaptively-secure in the non-erasure model, and at the same time completely avoi...

On the Security and Composability of the One Time Pad
Motivated by a potentially flawed deployment of the one time pad in a recent quantum cryptographic application securing a bank transfer [12], we show how to implement a statistica...

Adaptive Hardness and Composable Security in the Plain Model from Standard Assumptions
We construct the first general secure computation protocols that require no trusted infrastructure other than authenticated communication, and that satisfy a meaningful notion of s...

Breaking four mix-related schemes based on Universal Re-encryption
Universal Re-encryption allows El-Gamal ciphertexts to be re-encrypted without knowledge of their corresponding public keys. This has made it an enticing building block for anonymo...

Ideal Key Derivation and Encryption in Simulation-Based Security
Abstract. Many real-world protocols, such as SSL/TLS, SSH, IPsec, IEEE 802.11i, DNSSEC, and Kerberos, derive new keys from other keys. To be able to analyze such protocols in a com...
