"Geo-Encryption Lite" - A location based Encryption Application for Android

An Improved Geo-encryption Algorithm in Location Based Services

Wireless technology is used in many applications with location based data encryption techniques to secure the communication. The use of knowledge of the mobile user's location called Geo-encryption, produces more secure systems that can be used in different mobile applications. Location Based Data Encryption Methods (LBDEM) is a technique used to enhance the security of such applications called...

A stack-based chaotic algorithm for encryption of colored images

In this paper, a new method is presented for encryption of colored images. This method is based on using stack data structure and chaos which make the image encryption algorithm more efficient and robust. In the proposed algorithm, a series of data whose range is between 0 and 3 is generated using chaotic logistic system. Then, the original image is divided into four subimages, and these four i...

Geo-Encryption Protocol For Mobile Networks

We propose a geo-encryption protocol that allows mobile nodes to communicate securely by restricting the decryption of a message to a particular location and time period. Our protocol will handle the exchange of movement parameters, so that a sender is able to geoencrypt messages to a moving decryption zone that contains a mobile node’s estimated location. We also present methods for estimating...

Android full-disk encryption: a security assessment

Mobile phones evolved from basic telecommunication devices to smartphones which are, in essence, pocket computers. With this technological evolution their usage also changed. Nowadays users do not just keep contact details and text messages but also e-mails, chat communications, documents, browsing history and other data stored on their mobiles. Different actors are interested in this data: cri...
