State-Recovery Analysis of Spritz
RC4 suffered from a range of plaintext-recovery attacks using statistical biases, which use substantial, albeit close-to-practical, amounts of known keystream in applications such as TLS or WEP/WPA. Spritz was recently proposed at the rump session of CRYPTO 2014 as a slower redesign of RC4 by Rivest and Schuldt, aiming at reducing the statistical biases that lead to these attacks on RC4. Even m...
متن کاملHas Richard Rorty a moral philosophy?
در این مقاله سعی دارم نشان دهم که رورتی هرچند همانند کانت فیلسوف اخلاق محسوب نمیشود، ولی با این حال فلسفۀ اخلاقی دارد که باید آن را جدی گرفت. رورتی به نحو نظاممند با مسائل اخلاقی درگیر نمیشود آنطور که فیلسوفان مدرن و معاصر درگیرند. این مقاله دو بخش دارد: بخش نخست با مبانی فلسفۀ رورتی مثل ضد ماهیت باوری، داروینگرایی، فرویدگرایی و تاریخگرایی سروکار دارد. بخش دوم که تا حدودی مفصل است، بسیاری ...
متن کاملRandomness of Spritz via DieHarder testing
RC4 is a stream cipher included in the TLS protocol, and widely used for encrypting network traffic during the last decades. Spritz is a possible candidate for replacing RC4. Spritz is based on a sponge construction and preserves the byte-oriented behaviour existing in RC4, but introduces an interface that provides encryption, hashing or MAC-generation functionalities. We present here the resul...
متن کاملSpritz - a spongy RC4-like stream cipher and hash function
This paper reconsiders the design of the stream cipher RC4, and proposes an improved variant, which we call “Spritz” (since the output comes in fine drops rather than big blocks.) Our work leverages the considerable cryptanalytic work done on the original RC4 and its proposed variants. It also uses simulations extensively to search for biases and to guide the selection of intermediate expressio...
متن کاملState recovery of RC4 and Spritz Revisited
We provide an improved complexity analysis of backtracking-based state recovery attacks on RC4 and Spritz. Comparing new estimates with known results on Spritz, our analysis shows a signi cantly lower complexity estimate for simple state recovery attack as well as special state recovery attack. We validated the estimates by performing experiments for selected feasible parameters. We also propos...
