Abstract. In 1998, Boneh, Durfee and Frankel [4] presented several attacks on RSA when an adversary knows a fraction of the secret key bits. The motivation for these so-called part...
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...
We deal with computational assumptions needed in order to design secure cryptographic schemes. We suggest a classi£cation of such assumptions based on the complexity of falsifying...
The recently proposed universally composable (UC) security framework for analyzing security of cryptographic protocols provides very strong security guarantees. In particular, a p...
Classical distributed protocols like broadcast or multi-party computation provide security as long as the number of malicious players f is bounded by some given threshold t, i.e., ...
