第三个地址打开是： Nicolas T. Courtois research page My research: publications, presentations, talks, reports, courses, slides, + echoes in the press/Internet. Nicolas T. Courtois, Sean O'Neil and Jean-Jacques Quisquater: Practical Algebraic Attacks on the Hitag2 Stream Cipher, In 12th Information Security Conference, ISC 2009, Pisa, Italy 7-9 September 2009, Springer LNCS. Also will be presented at eSmart, the european smart card security conference, September 22-25, Sophia Antipolis, French Riviera, with proceedings (slides presented) being published as a CD-ROM. Card-only attacks on MiFare Crypto-1 cipher. Nicolas T. Courtois: The Dark Side of Security by Obscurity and Cloning MiFare Classic Rail and Building Passes Anywhere, Anytime , new attack requires only 300 queries to the card and will appear in SECRYPT 2009 - International Conference on Security and Cryptography: 7-10 July 2009, Milan, Italy. A version of this paper is available here. This paper concerns more than 1 billion of smart cards and compromises very heavily the security of thousands of buildings and several train/bus/parking payment systems in Europe and elsewhere (allowing for example unauthorized access to buildings, travel for free, free parking etc.). Other researchers also found other and different card-only attacks on MiFare Classic but they are more than 10 times more difficult to handle in terms of online time (more queries to the card, for example when standing or sitting next to the victim). The best practical attack currently known on MiFare Classic is actually a combination of our attack with 300 queries to find the first key (estimated time: 10 seconds with Proxmark3), and the Nested Authentication attack from the Oakland paper to recover all the other keys (which is extremely fast). Nicolas T. Courtois: Self-similarity Attacks on Block Ciphers and Application to KeeLoq, In International Workshop on Coding and Cryptography, May 10-15, 2009, Ullensvang, Norway. Algebraic attacks on MiFare Crypto-1 cipher. At eprint.iacr.org/2008/166/ This work was a bit of disappointment: we could recover the key in 12 seconds but this automated cryptanalysis, we did not realise how weak this cipher actually was, and later Dutch researchers have shown a simpler and better attack that does the job in less than 0.1 seconds (in contrast our attack is more generally applicable and can also break Hitag2, to appear soon).

Nicolas Courtois, Gregory V. Bard and David Wagner: Algebraic and Slide Attacks on KeeLoq. This paper describes 1) the first successful algebraic attack in history on a full round real-life block cipher 2) the fastest attack ever found on KeeLoq. The complexity of the latter is about 2^28 KeeLoq encryptions on average, and can be even 2^23 for a fraction of keys (see our next paper in preparation, not in FSE proceedings).

MinRank Foundation. promoting Multivariate Cryptography (..) Current encryption technology is based on mathematics developed in the 17th and 18th centuries, elliptic curve cryptography brings it forward into the mathematics of the 19th century (...) Whitfield Diffie, the inventor of public key cryptography, and now chief security officer at Sun Microsystems, during RSA Conference, Paris, October 2002. For the 20-th and 21-st centuries, we propose Multivariate Cryptography, that is based on Algebraic Geometry. Interesting links: Multivariate/Algebraic Cryptanalysis: Algebraic attacks on block ciphers: AES, Rijndael, Serpent, Camellia, DES, etc.. Algebraic attacks on stream ciphers Interesting links: Multivariate Cryptography: The McEliece_based short signature scheme CFS The HFE cryptosystem home page The Minrank Zero-knowledge identification scheme Quartz /Flash /Sflash signature schemes Nicolas Courtois research page TTM cryptosystem, GPT cryptosystem. 打开后觉得很奇怪呢，是不是这个东东哦？ |
