CWI cryptanalyst discovers new cryptographic attack variant in Flame spy malware
No full textCryptanalyst Marc Stevens from the Centrum Wiskunde & Informatica (CWI) in Amsterdam, known for breaking the https security in 2008 using a cryptanalytic attack on MD5, analyzed the recent Flame virus this week. He discovered that for this spy malware an as yet unknown cryptographic attack variant of his own MD5 attack is used. Stevens analyzed this with new forensic software that he developed. Initially, the researcher assumed that Flame used his own attack, which was made public in June 2009, but this was not the case. “Flame uses a completely new variant of a ‘chosen prefix collision attack’ to impersonate a legitimate security update from Microsoft. The design of this new variant required world-class cryptanalysis,” says Marc Stevens. “It is very important to invest in cryptographic research, to continue to be ahead of these developments in practice.
A survey of chosen-prefix collision attacks
No full textIn Chapter 7, A Survey of Chosen-Prefix Collision Attacks, Marc Stevens surveys the technical advances, impact and usage of collision attacks for the most widely used cryptographic hash functions. Cryptographic hash function are the Swiss army knives within cryptography and are used in many applications including digital signature schemes, message authentication codes, password hashing, cryptocurrencies and content-addressable storage. Stevens was one of the driving forces in turning initial weaknesses in the compression function into practical attacks against various widely deployed protocols relying on hash function collision resistance for their security. In Chapter 7 he explains how each scenario involves the development of slightly different ideas to exploit weaknesses in especially MD5
G6K-GPU-Tensor
No full textG6K is an open-source C++ and Python (2) library that implements several Sieve algorithms to be used in more advanced lattice reduction tasks. It follows the stateful machine framework from:
Martin R. Albrecht and Léo Ducas and Gottfried Herold and Elena Kirshanova and Eamonn W. Postlethwaite and Marc Stevens, The General Sieve Kernel and New Records in Lattice Reduction.
The main source is available in fplll/g6k
This fork expands the G6K implementation with GPU, and in particular Tensor Core, accelerated sieves, and is accompanied by the work:
Léo Ducas, Marc Stevens, Wessel van Woerden, Advanced Lattice Sieving on GPUs, with Tensor Cores, Eurocrypt 2021 (eprint).

UKMARC AMC: Draft Rev 4.0: UK MARC format for archives and manuscripts control (UK MARC AMC)
No full textThis draft is the first attempt to establish a UK MARC specifically for Archives and Manuscripts Control since the British Library indicated that it would countenance such extensions to the national UK MARC format. In order to keep consistency with the general UK MARC format, standard UK MARC subject fields are not included in this document, since they should be taken from the latest version of the UK MARC manual. {A note of them should perhaps be included in UK MARC AMC.} {NB Text in braces is intended to be explanatory material for readers of this draft}. Certain other fields have not been included that might occasionally be used in the cataloguing of archival materials but would generally only be used for such materials in organizations which were combining archive
databases with library databases. This MARC version is intended for use with descriptions of archive or anuscript material that follow, or fit, the traditional style of cataloguing: we assume that these will normally relate
to paper or parchment originals. It is not intended for use with descriptions of other kinds of material. For these, fields may be drawn from the appropriate UK MARC document. MARC versions for use with archives in special formats should be developed, in order to complete the full range of facilities available to archivists and curators
