On Memory-Bound Functions for Fighting Spam
In 1992, Dwork and Naor proposed that e-mail messages be accompanied by easy-to-check proofs of computational effort in order to discourage junk e-mail, now known as spam. They pro...

Fast Algebraic Attacks on Stream Ciphers with Linear Feedback
Many popular stream ciphers apply a filter/combiner to the state of one or several LFSRs. Algebraic attacks on such ciphers [10, 11] are possible, if there is a multivariate relat...

A Message Authentication Code Based on Unimodular Matrix Groups
We present a new construction based on modular groups. A novel element of our construction is to embed each input into a sequence of matrices with determinant ±1, the product of w...

Password Interception in a SSL/TLS Channel
Simple password authentication is often used e.g. from an email software application to a remote IMAP server. This is frequently done in a protected peer-to-peer tunnel, e.g. by SS...

The Impact of Decryption Failures on the Security of NTRU Encryption
NTRUEncrypt is unusual among public-key cryptosystems in that, with standard parameters, validly generated ciphertexts can fail to decrypt. This affects the provable security prop...

Derandomization in Cryptography
We give two applications of Nisan–Wigderson-type (“non-cryptographic”) pseudorandom generators in cryptography. Specifically, assuming the existence of an appropriate NW-ty...
