  The crypto group of TELECOM-ParisTech is looking for six Ph.D. students, on various topics linked to side-channel cryptanalysis.

The subjects are:

  1. Fault Injection for Reverse-Engineering (FIRE)

  2. Electromagnetic observation and injection, using information-theoretic tools

  3. Formal proof of countermeasures against attacks targeting cryptographic implementations

  4. Bus and memory encryption/integrity in embedded systems with SecBus — hardware aspects

  5. Information leakage of NFC-enabled smartphones by magnetic analysis

  6. Distinguishing side-channel distinguishers

07:36 [Job][Update] Lecturer, Queensland University of Technology, Brisbane, Australia


The Queensland University of Technology (QUT) in Brisbane, Australia, invites applications for full-time Lecturer positions starting in 2012. Up to nine positions are available in the Science and Engineering Faculty.

The Science and Engineering Faculty at QUT has an active research group in cryptography, network security, and digital forensics, with a leading national profile and strong international links.

Applicants should have completed (or be under examination for) a PhD and be early career researchers (less than three years in an academic role). Appointee(s) will develop and maintain an active research program, teach at undergraduate and graduate levels, supervise research students, and participate in QUT\\\'s Early Career Academic Development program.

00:17 [Pub][ePrint] Quantifying Side-Channel Information Leakage from Web Applications, by Luke Mather and Elisabeth Oswald

  Recent research has shown that many popular web applications are vulnerable to side-channel attacks on encrypted streams of network data produced by the interaction of a user with an application. As a result, private user data is susceptible to being recovered by a side-channel adversary. A recent focus has been on the development of tools for the detection and quantification of side-channel information leaks from such web applications. In this work we describe a model for these web applications, analyse the effectiveness of previous approaches for the quantification of information leaks, and describe a robust, effective and generically applicable metric based on a statistical estimation of the mutual information between the user inputs made in the application and subsequent observable side-channel information. We use our proposed metric to construct a test capable of analysing sampled traces of packets to detect information leaks, and demonstrate the application of our test on a real-world web application.

21:17 [Pub][ePrint] Self-pairings on Hyperelliptic Curves, by Steven D. Galbraith and Chang-An Zhao

  A self-pairing is a pairing computation where both inputs are the same group element. Self-pairings are used in some cryptographic schemes and protocols. In this paper, we show how to compute the Tate-Lichtenbaum pairing (D,\\phi(D)) on a curve more efficiently than the general case. The speedup is obtained by requiring a simpler final exponentiation. We also discuss how to use this pairing in cryptographic applications.

21:17 [Pub][ePrint] On a CCA2-secure variant of McEliece in the standard model, by Edoardo Persichetti

  We consider public-key encryption schemes based on error-correcting

codes that are IND-CCA2 secure in the standard model. We analyze a system due

to Dowsley, Muller-Quade and Nascimento. We then show how to instantiate the

Rosen-Segev framework with the McEliece scheme.

•Analysis of “real world” protocols

•Formal Methods applied to security protocols

•Fully Homomorphic Encryption

•Lattice Based Cryptography

•Provable Security, i.e. Protocol and Mechanism design

The post is funded by an ERC Advanced Grant awarded to Prof. Nigel Smart.

The expected starting date will be as soon as possible depending on the your circumstances.

18:10 [PhD][New] Côme Berbain: Analyse et conception d\'algorithmes de chiffrement à flot

  Name: Côme Berbain
Topic: Analyse et conception d\'algorithmes de chiffrement à flot
Category: secret-key cryptography


The primary goal of cryptography is to protect the confidentiality of data and communications. Stream ciphers is one of the two most popular families of symmetric encryption algorithms that allow to guaranty\r\nconfidentiality and to achieve high performances.


In the first part of this thesis, we present different cryptanalysis techniques against stream ciphers: correlation\r\nattack against the stream cipher GRAIN, guess and determine attack against the BSG mechanism, algebraic attack against special\r\nkinds of non-linear feedback shift registers, and chosen IV attack against a reduced version of the stream cipher SALSA.


In a second part, we focus on proofs of security for stream ciphers: we introduce the new algorithm QUAD and give some \r\nprovable security arguments in order to link its security to the conjectured intractability of Multivariate Quadratic problem. We also try to extend the security requirements of stream ciphers to the case where initialisation values (IV) are used: we present a construction which allows us\r\nto build a secure IV dependent stream cipher from a number generator and apply it to QUAD, which becomes the first IV dependent\r\nstream cipher with provable security arguments. We also present the algorithms DECIM and SOSEMANUK, to which we made\r\ndesign contributions.


Finally in a third part, we present efficient software and hardware implementations of the QUAD algorithm.
