Topological Graphic Passwords And Their Matchings Towards Cryptography

Graph Theory Towards New Graphical Passwords In Information Networks

Graphical passwords (GPWs) have been studied over 20 years. We are motivated from QR codes that can be considered GPWs, are successfully applied in today's world. However, one need such GPWs that can be use conveniently and have higher level security in information networks. We aim to GPWs for mobile devices with touch screen. No more researching papers of GPWs by means of techniques of graph theory that are already used in a wide range of scientific areas, especially, dynamic networks. Our investigation is devoted to designing new type of graphical passwords by methods of graph theory, such a…

SD-EQR：一种在密码学中使用QR CodesTM的新技术

SD-EQR: A New Technique To Use QR CodesTM in Cryptography

在本文中，作者提出了一种新的技术，使用QR码（俗称“快速响应码”）在密码学领域。QR码主要用于传达或存储信息，因为它们具有比任何其他常规“条形码”更高或更大的存储容量。在本文中，主要关注的是使用密码以加密格式存储消息，并将其发送到隐藏在QR码中的所需目的地，而不会被任何黑客或间谍软件正确跟踪或解密。由于QR码具有快速的响应时间和大的存储容量，QR码可以完美地用于向接收器发送加密数据（消息）。这种方法将适用于任何商业机构，政府部门，通信网络，以更快地将其加密消息发送到目的地。或者一个人甚至可以使用这种方法来保持他的重要文件，如护照号码，泛卡身份证，社会安全号码，完全安全与他所有的时间，没有信息泄露给外界。新方法是通过输入消息和密码来实现的。此密码将生成一个密码，该密码将添加到消息中输入的数字或文本中的每个数字或字母（需要加密），并生成第一阶段的加密。新生成的加密消息将使用各种其他方法再次加密，以生成最终的加密消息。

A Survey of Collection Methods and Cross-Data Set Comparison of Android Unlock Patterns

Android's graphical password unlock remains one of the most widely used schemes for phone unlock authentication, and it is has been studied extensively in the last decade since its launch. We have learned that users' choice of patterns mimics the poor password choices in other systems, such as PIN or text-based passwords. A wide variety of analysis and data collections methods was used to reach these conclusions, but what is missing from the literature is a systemized comparison of the related work in this space that compares both the methodology and the results. In this paper, we take a detai…

Topological Authentication Technique In Topologically Asymmetric Cryptosystem

Making topological authentication from theory to practical application is an important and challenging task. More and more researchers pay attention on coming quantum computation, privacy data protection, lattices and cryptography. Research show the advantages of topological authentications through graph operations, various matrices, graph colorings and graph labelings are: related with two or more different mathematical areas, be not pictures, there are huge number of colorings and labelings, rooted on modern mathematics, diversity of asymmetric ciphers, simplicity and convenience, easily cre…
