Forward Secure Signatures on Smart CardsMSS. In contrast to the only previous implementation of a hash-based signature scheme on smart cards by Rohde et al., we solve the problem of on-card key generation. Compared to XMSS, we reduce the key generation time from . to ., where . is the number of signatures that can be created with one key

Extracts from the SHA-3 Competition1, 2] and at Crypto 2005 [3, 4]. Collisions were given for the hash functions MD4, MD5, RIPEMD and SHA-0. An algorithm was shown that can produce collisions for SHA-1 with a complexity that is much lower than previously thought. Before 2005, there were already partial attacks known for several of th

Cryptanalysis of the “Kindle” Ciphercademic cryptanalysis of this cipher and it shows that PC1 is a very weak stream cipher, and can be practically broken in a known-plaintext and even in a ciphertext-only scenario..A hash function based on this cipher has also been proposed and is implemented in the binary editor WinHex. We show that

Cryptographically Strong de Bruijn Sequences with Large Periods the feedback functions that generate de Bruijn sequences. The cycle structures of the approximated feedback functions and the linear complexity of a sequence produced by an approximated feedback function are determined. Furthermore, we present a compact representation of an (. + 16)-stage nonlinear

Cryptanalysis of the Loiss Stream Cipherists of a linear feedback shift register (LFSR) and a non-linear finite state machine (FSM). Loiss utilizes a structure called Byte-Oriented Mixer with Memory (BOMM) in its filter generator, which aims to improve resistance against algebraic attacks, linear distinguishing attacks and fast correlatio

Towards Faster and Greener Cryptoprocessor for Eta Pairing on Supersingular Elliptic Curve over ,ring at the 128-bit security level in less than one milli-second. The high performance of their cryptoprocessor comes largely from the use of the Karatsuba method for field multiplication. In this article, for the same type of pairing we propose hybrid sequential/parallel multipliers based on the To

Feasibility and Practicability of Standardized Cryptography on 4-bit Micro Controllersremote access and control systems or all sort of sensors. Yet the feasibility and practicability of standardized cryptography on 4-bit MCUs has been mostly neglected. In this work we close this gap and provide, to the best of our knowledge, the first implementations of . and ., and the fastest imple

All Subkeys Recovery Attack on Block Ciphers: Extending Meet-in-the-Middle Approachstrictive. In other words, most of the recent MITM attacks work only on block ciphers consisting of a bit permutation based key schedule such as KTANTAN, GOST, IDEA, XTEA, LED and Piccolo. In this paper, we extend the MITM attack so that it can be applied to a wider class of block ciphers. In our ap
