Lattice and code cryptography can replace existing schemes such as elliptic curve because of their resistance to quantum computers. In support public key infrastructures, the distribution, validation storage cryptographic keys is then more complex for handling longer keys. This paper describes practical ways generate from physical unclonable functions, both lattice code-based cryptography. Hand...

Code-based cryptography is one of few alternatives supposed to be secure in a post-quantum world. Meanwhile, identity-based identification and signature (IBI/IBS) schemes are two of the most fundamental cryptographic primitives, so several code-based IBI/IBS schemes have been proposed. However, with increasingly profound researches on coding theory, the security reduction and efficiency of such...

A multi-purpose image-based QR code is designed in this paper. There are four purposes for the generated code. In first purpose, basic with look of a host image an ingenious layout to be identified easier. second one, saliency region detection method adopted enhancing quality third embedded into further access image; Finally, visual cryptography-based watermarking applied case that specific use...

We study the distinguishability of linearized Reed–Solomon (LRS) codes by defining and analyzing analogs square-code Overbeck distinguisher for classical Gabidulin codes, respectively. Our main results show that works generalized (GLRS) defined with trivial automorphism, whereas Overbeck-type can handle LRS in general setting. further how to recover code parameters from any generator matrix suc...

One of the most important consideration techniques when one want to solve the protecting of digital signal is the golden matrix. The golden matrices can be used for creation of a new kind of cryptography called the golden cryptography. Many research papers have proved that the method is very fast and simple for technical realization and can be used for cryptographic protection of digital signal...

A conjugate code pair is defined as a pair of linear codes such that one contains the dual of the other. The conjugate code pair represents the essential structure of the corresponding Calderbank-Shor-Steane (CSS) quantum code. It is argued that conjugate code pairs are applicable to quantum cryptography in order to motivate studies on conjugate code pairs.

A conjugate code pair is defined as a pair of linear codes either of which contains the dual of the other. A conjugate code pair represents the essential structure of the corresponding Calderbank-Shor-Steane (CSS) quantum code. It is known that conjugate code pairs are applicable to (quantum) cryptography. We give a construction method for efficiently decodable conjugate code pairs.

Code-based cryptography is often viewed as an interesting “Post-Quantum” alternative to the classical number theory cryptography. Unlike many other such alternatives, it has the convenient advantage of having only a few, well identified, attack algorithms. However, improvements to these algorithms have made their effective complexity quite complex to compute. We give here some lower bounds on t...

One of the huge problems for security in sensor networks is the lack of resources. Typical sensor nodes such as the quite popular MICA and MICA2 Motes from UC Berkeley [1] are based on a microcontroller architecture with only a few KBytes of memory and severe limited computing ability. Strong publickey cryptography is therefore commonly seen as infeasible on such devices. In contrast to this pr...
