Related-Key Cryptanalysis of 3-WAY, Biham-DES,CAST, DES-X, Newdes, RC2, and TEA
Related-Key Cryptanalysis of 3-WAY, Biham-DES,CAST, DES-X, NewDES, RC2, and TEA John Kelsey Bruce Schneier David Wagner Counterpane Systems U.C. Berkeley kelsey,schneier @counterpane.com [email protected] f g Abstract. We present new related-key attacks on the block ciphers 3- WAY, Biham-DES, CAST, DES-X, NewDES, RC2, and TEA. Differen- tial related-key attacks allow both keys and plaintexts to be chosen with specific differences [KSW96]. Our attacks build on the original work, showing how to adapt the general attack to deal with the difficulties of the individual algorithms. We also give specific design principles to protect against these attacks. 1 Introduction Related-key cryptanalysis assumes that the attacker learns the encryption of certain plaintexts not only under the original (unknown) key K, but also under some derived keys K0 = f(K). In a chosen-related-key attack, the attacker specifies how the key is to be changed; known-related-key attacks are those where the key difference is known, but cannot be chosen by the attacker. We emphasize that the attacker knows or chooses the relationship between keys, not the actual key values. These techniques have been developed in [Knu93b, Bih94, KSW96]. Related-key cryptanalysis is a practical attack on key-exchange protocols that do not guarantee key-integrity|an attacker may be able to flip bits in the key without knowing the key|and key-update protocols that update keys using a known function: e.g., K, K + 1, K + 2, etc. Related-key attacks were also used against rotor machines: operators sometimes set rotors incorrectly. -

Miss in the Middle
Miss in the middle By: Gal Leonard Keret Miss in the Middle Attacks on IDEA, Khufu and Khafre • Written by: – Prof. Eli Biham. – Prof. Alex Biryukov. – Prof. Adi Shamir. Introduction • So far we used traditional differential which predict and detect statistical events of highest possible probability. Introduction • A new approach is to search for events with probability one, whose condition cannot be met together (events that never happen). Impossible Differential • Random permutation: 휎 푀0 = 푎푛푦 퐶 표푓 푠푖푧푒 푀0. • Cipher (not perfect): 퐸 푀0 = 푠표푚푒 퐶 표푓 푠푖푧푒 푀0. • Events (푚 ↛ 푐) that never happen distinguish a cipher from a random permutation. Impossible Differential • Impossible events (푚 ↛ 푐) can help performing key elimination. • All the keys that lead to impossibility are obviously wrong. • This way we can filter wrong key guesses and leaving the correct key. Enigma – for example • Some of the attacks on Enigma were based on the observation that letters can not be encrypted to themselves. 퐸푛푖푔푚푎(푀0) ≠ 푀0 In General • (푀0, 퐶1) is a pair. If 푀0 푀0 → 퐶1. • 푀 ↛ 퐶 . 0 0 Some rounds For any key • ∀ 푘푒푦| 퐶1 → 퐶0 ↛ is an impossible key. Cannot lead to 퐶0. Some rounds Find each keys Decrypt 퐶1back to 퐶0. IDEA • International Data Encryption Algorithm. • First described in 1991. • Block cipher. • Symmetric. • Key sizes: 128 bits. • Block sizes: 64 bits. ⊕ - XOR. ⊞ - Addition modulo 216 ⊙ - Multiplication modulo 216+1 Encryption security • Combination of different mathematical groups. • Creation of "incompatibility“: ∗ • 푍216+1 → 푍216 ∗ • 푍216 → 푍216+1 ∗ ∗ Remark: 푍216+1 doesn’t contain 0 like 푍216 , so in 푍216+1 0 will be converted to 216 since 0 ≡ 216(푚표푑 216). -

Cryptanalysis of a Reduced Version of the Block Cipher E2
Cryptanalysis of a Reduced Version of the Block Cipher E2 Mitsuru Matsui and Toshio Tokita Information Technology R&D Center Mitsubishi Electric Corporation 5-1-1, Ofuna, Kamakura, Kanagawa, 247, Japan [email protected], [email protected] Abstract. This paper deals with truncated differential cryptanalysis of the 128-bit block cipher E2, which is an AES candidate designed and submitted by NTT. Our analysis is based on byte characteristics, where a difference of two bytes is simply encoded into one bit information “0” (the same) or “1” (not the same). Since E2 is a strongly byte-oriented algorithm, this bytewise treatment of characteristics greatly simplifies a description of its probabilistic behavior and noticeably enables us an analysis independent of the structure of its (unique) lookup table. As a result, we show a non-trivial seven round byte characteristic, which leads to a possible attack of E2 reduced to eight rounds without IT and FT by a chosen plaintext scenario. We also show that by a minor modification of the byte order of output of the round function — which does not reduce the complexity of the algorithm nor violates its design criteria at all —, a non-trivial nine round byte characteristic can be established, which results in a possible attack of the modified E2 reduced to ten rounds without IT and FT, and reduced to nine rounds with IT and FT. Our analysis does not have a serious impact on the full E2, since it has twelve rounds with IT and FT; however, our results show that the security level of the modified version against differential cryptanalysis is lower than the designers’ estimation. -

The Architecture of Joseph Michael Gandy (1771-1843) and Sir John Soane (1753-1837): An Exploration Into the Masonic and Occult Imagination of the Late Enlightenment Abstract In examining select works of English architects Joseph Michael Gandy and Sir John Soane, this dissertation is intended to bring to light several important parallels between architectural theory and freemasonry during the late Enlightenment. Both architects developed architectural theories regarding the universal origins of architecture in an attempt to establish order as well as transcend the emerging historicism of the early nineteenth century. There are strong parallels between Soane's use of architectural narrative and his discussion of architectural 'model' in relation to Gandy's understanding of 'trans-historical' architecture. The primary textual sources discussed in this thesis include Soane's Lectures on Architecture, delivered at the Royal Academy from 1809 to 1836, and Gandy's unpublished treatise entitled the Art, Philosophy, and Science of Architecture, circa 1826. -

Hawara & Meidum Add-On
Hawara & Meidum add-on (day 1 of the tour) - $195 per person Do you want to see even more pyramids in Egypt? For the guests who would like to arrive one day early, we prepared a trip to Hawara and Meidum pyramids. On that day we normally organize reception at the airport for the arriving guests, but you will drive towards Faiyum oasis and make a stop in Meidum. In many ways, Meidum, built for pharaoh Snefru, is the most mysterious of all the great Pyramids. It is often known as the "collapsed pyramid" because of its ruined state. It seems to have been designed as a seven step pyramid with a further step being added once construction was in a fairly advanced stage. It was then turned into the first true pyramid by filing in the steps and capping them with limestone. No sarcophagus was found inside the chamber and there is no evidence that Snefru or anyone else was ever buried in this pyramid. We will enter inside the pyramid and later we will also visit a nearby mastaba of an unknown noble which can be entered via a robber's tunnel. The burial chamber contains the first example of a red granite sarcophagus known in antiquity. After the visit in Meidum, we will drive south to see the Hawara pyramid. The pyramid stands in the north of an elaborate complex enclosed by a wall measuring 385 by 158 meters. This makes the Hawara complex the largest Middle Kingdom funerary complex. The entrance was located at the southern corner of the east wall. -
Safer Than You Think! Revising the Transit Safety Narrative 1 September 2021
www.vtpi.org [email protected] 250-508-5150 Safer Than You Think! Revising the Transit Safety Narrative 1 September 2021 Todd Litman Victoria Transport Policy Institute Abstract Public transportation is overall a relatively safe (low crash risk) and secure (low crime risk) mode of transport. Transit travel has about a tenth the traffic casualty (death or injury) rate as automobile travel, and transit-oriented neighborhood residents have about a fifth the per capita crash casualty rate as in automobile-oriented areas. Transit also tends to have lower overall crime rates than automobile travel, and many transit service improvements can further increase security by improving surveillance and economic opportunities for at-risk populations. Despite its relative safety and security, many people consider public transit dangerous, and so are reluctant to use it or support service expansions in their communities. Various factors contribute to this excessive fear, including the nature of public transit travel, heavy media coverage of transit- related crashes and crimes, and conventional traffic safety messages which emphasize danger rather than safety. Transit agencies can help create a new safety narrative by better measuring and communicating transit’s overall safety and security impacts, and providing better guidance concerning how users and communities can enhance transit safety and security.

Miss in the Middle Attacks on IDEA and Khufu
Miss in the Middle Attacks on IDEA and Khufu Eli Biham? Alex Biryukov?? Adi Shamir??? Abstract. In a recent paper we developed a new cryptanalytic techni- que based on impossible differentials, and used it to attack the Skipjack encryption algorithm reduced from 32 to 31 rounds. In this paper we describe the application of this technique to the block ciphers IDEA and Khufu. In both cases the new attacks cover more rounds than the best currently known attacks. This demonstrates the power of the new cryptanalytic technique, shows that it is applicable to a larger class of cryptosystems, and develops new technical tools for applying it in new situations. 1 Introduction In [5,17] a new cryptanalytic technique based on impossible differentials was proposed, and its application to Skipjack [28] and DEAL [17] was described. In this paper we apply this technique to the IDEA and Khufu cryptosystems. Our new attacks are much more efficient and cover more rounds than the best previously known attacks on these ciphers. The main idea behind these new attacks is a bit counter-intuitive. Unlike tra- ditional differential and linear cryptanalysis which predict and detect statistical events of highest possible probability, our new approach is to search for events that never happen. Such impossible events are then used to distinguish the ci- pher from a random permutation, or to perform key elimination (a candidate key is obviously wrong if it leads to an impossible event). The fact that impossible events can be useful in cryptanalysis is an old idea (for example, some of the attacks on Enigma were based on the observation that letters can not be encrypted to themselves).
