Reducing Complexity Assumptions for Statistically-Hiding Commitment
We revisit the following question: what are the minimal assumptions needed to construct statistically-hiding commitment schemes? Naor et al. show how to construct such schemes bas...

Computational Indistinguishability Between Quantum States and Its Cryptographic Application
We introduce a computational problem of distinguishing between two specific quantum states as a new cryptographic problem to design a quantum cryptographic scheme that is “secu...

Predicting and Distinguishing Attacks on RC4 Keystream Generator
In this paper we analyze the statistical distribution of the keystream generator used by the stream ciphers RC4 and RC4A. Our first result is the discovery of statistical biases o...

Fuzzy Identity-Based Encryption
We introduce a new type of Identity-Based Encryption (IBE) scheme that we call Fuzzy Identity-Based Encryption. In Fuzzy IBE we view an identity as set of descriptive attributes. ...

Cryptanalysis of the Hash Functions MD4 and RIPEMD
MD4 is a hash function developed by Rivest in 1990. It serves as the basis for most of the dedicated hash functions such as MD5, SHAx, RIPEMD, and HAVAL. In 1996, Dobbertin showed ...
