A NovelQR-Code Authentication Protocol Using Visual Cryptography for Secure Communications
نویسنده
چکیده
Visual cryptography (VC) is a distinct type of secret sharing scheme which hides secret images in share images such that, when the shares are superimposed, a hidden secret image is revealed. It does not require the complex computational method to decode the secret information. The paper proposes a novel Quick Response (QR) code authentication system using Visual Cryptography. The passwords for authentication are encoded as QR-codes and later encrypted into share images. Thus, the share images by itself convey no information, but when the layers are combined, the secret password is revealed. The only necessary is that the user needs to handle a device containing a QR-code reader, most probably a Smartphone. The experimental result shows that the proposed QAP scheme provides secure data transmission with less computational complexity.

Provably secure and efficient identity-based key agreement protocol for independent PKGs using ECC
Key agreement protocols are essential for secure communications in open and distributed environments. Recently, identity-based key agreement protocols have been increasingly researched because of the simplicity of public key management. The basic idea behind an identity-based cryptosystem is that a public key is the identity (an arbitrary string) of a user, and the corresponding private key is ...

متن کاملAn efficient secure channel coding scheme based on polar codes
In this paper, we propose a new framework for joint encryption encoding scheme based on polar codes, namely efficient and secure joint secret key encryption channel coding scheme. The issue of using new coding structure, i.e. polar codes in Rao-Nam (RN) like schemes is addressed. Cryptanalysis methods show that the proposed scheme has an acceptable level of security with a relatively smaller ke...
