Arithmetic operators on GF(2m) for cryptographic applications: performance - ...
The efficiency of devices performing arithmetic operations in finite field is crucial for the efficiency of ECC systems. Regarding the dependency of the system on... -
(Non-)Interactive Proofs of Knowledge
In this thesis, we create new building blocks and use them to present new efficient protocols via a modular design. We first begin by using the Groth-Sahai methodology... -
Escaping from Babel : a Republic of Languages in search of a “Universal Langu...
During the Early Modern Age, Europe was the field of a protean quest for the universal language (researches on Adam’s language were carried out, encyclopedias of all... -
List Decoding and application to information security
This thesis studies some aspects of error-correcting codes and their applications to information security. We focused more specifically on the maximum-likelyhood and... -
Optimization methods for side channel attacks
The security of modern embedded systems has been the subject of intensive research in engineering areas. Recent threats called Side-Channel Analysis (SCA) have... -
User identity based authentication mechanisms for network security enhancement
In this thesis, we design three new authentication mechanisms based on user identity. Therefore, we bring improvements in access control for different classes of... -
Key Exchange and Encryption Schemes Based on Non-commutative Skew Polynomials
In this paper we introduce a new key exchange algorithm (Diffie-Hellman like) based on so called (non-commutative) skew polynomials. The algorithm performs only... -
Remote object authentication protocols
This thesis is dedicated to the description of several bitrsitring comparison based remote object authentication protocols and the study of their theoretical security.... -
Contribution of Non Integer Integro-Differential Operators (NIDO) to the geom...
Advances in fractional analysis suggest a new way for the physics understanding of Riemann's conjecture. It asserts that, if s is a complex number, the non trivial... -
Pocket Bluff : A cooperation enforcing scheduled pocket switching protocol
We propose Pocket Bluff; a novel pocket switched message forwarding protocol that can foil selfish/malicious nodes that deliberately drop data. Pocket Bluff hides the... -
Computationally Sound, Automated Proofs for Security Protocols
Since the 1980s, two approaches have been developed for analyzing security protocols. One of the approaches relies on a computational model that considers issues of... -
Nonlinear dynamics of photonic components. Chaos cryptography and multiplexing
With the rapid development of optical communications and the increasing amount of data exchanged, it has become utterly important to provide effective architectures to... -
A Pseudo-Random Bit Generator Using Three Chaotic Logistic Maps
A novel pseudo-random bit generator (PRBG) using three chaotic logistic maps is proposed. The algorithm generates at each iteration sequences of 32 bit-blocks by... -
