On the Security of Certificateless Signature Schemes

International Journal of Distributed Sensor Networks, 2013
Wireless Sensor Network (WSN) has proved its presence in various real time applications and hence the security of such embedded devices is a vital issue. Certificateless cryptography is one of the recent paradigms to provide security.

New Directions in Multivariate Public Key Cryptography [PDF]

, 2009
Most public key cryptosystems used in practice are based on integer factorization or discrete logarithms (in finite fields or elliptic curves). However, these systems suffer from two potential drawbacks.

Cryptography: Classical versus Post-Quantum [PDF]

arXiv
The advantages of post-quantum cryptography over classical cryptography are covered in this survey. We address several post-quantum cryptography techniques. We conclude that the deployment of quantum-safe cryptographic systems is anticipated to be the future of secure communication, and that the development of post-quantum cryptography is essential to ...

Trusted Certificates in Quantum Cryptography [PDF]

arXiv, 2006
This paper analyzes the performance of Kak's three stage quantum cryptographic protocol based on public key cryptography against a man-in-the-middle attack. A method for protecting against such an attack is presented using certificates distributed by a trusted third party.

Tensor-based trapdoors for CVP and their application to public key cryptography [PDF]

, 2000
We propose two trapdoors for the Closest-Vector-Problem in lattices (CVP) related to the lattice tensor product.

RSA: Dagli anni '70 al giorno d'oggi

Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2006
In this note, after a brief historical excursus, we describe the revolution in cryptography of the 70es, due to the introduction of public key cryptography and the RSA algorithm. We also consider some contemporary applications of this algorithm.

Implementing the Three-Stage Quantum Cryptography Protocol [PDF]

arXiv, 2006
We present simple implementations of Kak's three-stage quantum cryptography protocol. The case where the transformation is applied to more than one qubit at the same time is also considered.

Full Restoration of Visual Encrypted Color Images [PDF]

arXiv, 2011
While strictly black and white images have been the basis for visual cryptography, there has been a lack of an easily implemented format for colour images. This paper establishes a simple, yet secure way of implementing visual cryptography with colour, assuming a binary data representation.
