Cryptanalysis of SFLASH with Slightly Modified Parameters
SFLASH is a signature scheme which belongs to a family of multivariate schemes proposed by Patarin et al. in 1998 [9]. The SFLASH scheme itself has been designed in 2001 [8] and ha...

Round-Efficient Secure Computation in Point-to-Point Networks
Essentially all work studying the round complexity of secure computation assumes broadcast as an atomic primitive. Protocols constructed under this assumption tend to have very poo...

An Efficient Protocol for Secure Two-Party Computation in the Presence of Malicious Adversaries
We show an efficient secure two-party protocol, based on Yao's construction, which provides security against malicious adversaries. Yao's original protocol is only secur...

Differential Cryptanalysis of the Stream Ciphers Py, Py6 and Pypy
This paper shows that Py and Pypy are practically insecure. If one key is used with about 216 IVs with special differences, with high probability two identical keystreams will appe...

Three-Round Abuse-Free Optimistic Contract Signing with Everlasting Secrecy
We introduce the novel notion of Verifiable Encryption of Chameleon Signatures (VECS), and then use it to design a three-round abuse-free optimistic contract signing protocol. Key...
