Identity-Based Multi-signatures from RSA
Abstract. Multi-signatures allow multiple signers to jointly authenticate a message using a single compact signature. Many applications however require the public keys of the signe...

Compact E-Cash from Bounded Accumulator
Abstract. Known compact e-cash schemes are constructed from signature schemes with efficient protocols and verifiable random functions. In this paper, we introduce a different ap...

Improved Efficiency for Private Stable Matching
At Financial Crypto 2006, Golle presented a novel framework for the privacy preserving computation of a stable matching (stable marriage). We show that the communication complexity...

Differential Power Analysis of Stream Ciphers
Side-channel attacks on block ciphers and public key algorithms have been discussed extensively. However, there is only sparse literature about side-cannel attacks on stream cipher...

Selecting Secure Passwords
We mathematically explore a model for the shortness and security for passwords that are stored in hashed form. The model is implicitly in the NIST publication [8] and is based on c...

How to Strengthen Any Weakly Unforgeable Signature into a Strongly Unforgeable Signature
Standard signature schemes are usually designed only to achieve weak unforgeability – i.e. preventing forgery of signatures on new messages not previously signed. However, most s...

Cryptanalysis of Reduced Variants of the FORK-256 Hash Function
FORK-256 is a hash function presented at FSE 2006. Whereas SHA-like designs process messages in one stream, FORK-256 uses four parallel streams for hashing. In this article, we pre...
