Provable Security of Networks

open access: yesCoRR, 2013
We propose a definition of {\it security} and a definition of {\it robustness} of networks against the cascading failure models of deliberate attacks and random errors respectively, and investigate the principles of the security and robustness of networks. We propose a {\it security model} such that networks constructed by the model are provably secure

Provable Secure Generalized Signcryption [PDF]

open access: yesJournal of Computers, 2010
Generalized signcryption which proposed by Han is a new cryptographic primitive which can work as an en- cryption scheme, a signature scheme or a signcryption scheme[5]. However,the security proof in their paper is uncorrect. our contribution are as following:First we give security notions for this new primitive.Secnond,we give an attack to [4] which ...

Provable security against generic attacks on stream ciphers

open access: yesJournal of Mathematical Cryptology, 2023
Recent lightweight hardware-based stream cipher designs keep an external non-volatile internal state that is not part of the cipher’s hardware module. The purpose of these so-called small-state ciphers is to keep the size of the hardware and the power ...

Provable security for cryptographic protocols - exact analysis and engineering applications

open access: yes, 1997
We develop an approach to deriving concrete engineering advice for cryptographic protocols from provable-security-style proofs of security. The approach is illustrated with a simple, yet useful protocol. Our main result provides the first published proof

Provable Security Analysis of FIDO2 [PDF]

open access: yes, 2022
We carry out the first provable security analysis of the new FIDO2 protocols, the promising FIDO Alliance\u27s proposal for a standard for passwordless user authentication.

Interpreting Hash Function Security Proofs [PDF]

open access: yes
We provide a concrete security treatment of several "provably secure" hash functions. Interpreting arguments behind MQ-HASH, FSB, SWIFFTX and VSH we identify similar lines of reasoning. We aim to formulate the main security claims in a language closer to

An Experiment in Interoperable Cryptographic Protocol Implementation Using Automatic Code Generation [PDF]

open access: yes, 2007
Spi2Java is a tool that enables semi-automatic generation of cryptographic protocol implementations, starting from verified formal models. This paper shows how the last version of spi2Java has been enhanced in order to enable interoperability of the ...

Provably Secure Masking of AES [PDF]

open access: yes, 2004
A general method to secure cryptographic algorithms against side-channel attacks is the use of randomization techniques and, in particular, masking. Roughly speaking, using random values unknown to an adversary one masks the input to a cryptographic algorithm.

On Large Tweaks in Tweakable Even-Mansour with Linear Tweak and Key Mixing

open access: yesIACR Transactions on Symmetric Cryptology, 2023
In this paper, we provide the first analysis of the Iterated Tweakable Even-Mansour cipher with linear tweak and key (or tweakey) mixing, henceforth referred as TEML, for an arbitrary tweak(ey) size kn for all k ≥ 1, and arbitrary number of rounds r ≥ 2.
