A Study of Email Encryption on Android OS. International Journal of Information Engineering and Applications. Vol. 1, No. 2, 2018, pp. 67-70. Received : January 27, 2018; Accepted : February 18, 2018; Published : March 23, 2018 Abstract: In the past, mobile devices are used for making/receiving calls and SMS. Smartphones become the most common and typical mobile devices in recent years. They merge the PDA (personal digital assistant) with the functionality of mobile phone. Moreover, they are provided many functionality of the computers, such as processing, communication, data storage and etc. Also, they provide many services that the computers make them available, for example web browser, video call, GPS, Wi- Fi, different social media application and etc. Recently, email is one of many relevant communication services that accessed commonly using smartphones. One of most popular operating systems in smartphones that using it, is android. In this paper, email encryption on android is present using Asymmetric key for files, emails, and texts to encrypt/ decrypt, sign email/file, and verify. Both OpenKeychain and Samsung email is used in this paper to simulate the use of PGP on android. This paper proposed the use of asymmetric in the same mobile application which is compatible with all OS platforms software. Keywords: Mobile Security, Android, Security, Email, Encryption, Public Key 1. -

Digital Privacy a Guide to Giving Nsa the Finger
A REPORT FROM SOVEREIGNMAN.COM DIGITAL PRIVACY A GUIDE TO GIVING NSA THE FINGER.. WITHOUT THEM EVER NOTICING A BLACK PAPER DIGITAL A BLACK PRIVACY PAPER I’m not here to tell you that we are being spied on. That Facebook is keeping track of you and your friends. That Google is storing your searches, your locations, your emails, your browsing history. Everything. That the NSA can listen in on every phone call and read every text message. Everybody knows that. They know it. We know it. We know that they track our every move. We know about their social network profiling and enormous data centers they are building all over the country. As I’ve said before, from Obama’s ‘kill switch’, to ACTA, SOPA and PIPA, to stasi tactics against people like Kim Dotcom, hardly a month goes by without some major action against Internet users. But it’s what’s going on in the background that you should be worried about. As William Binney, another NSA whistleblower and the agency’s former Technical Director, recently told me in the May 2013 edition of our premium service, Sovereign Man: Confidential— “It was around 2003 when they started putting optical fibers coming into the US through Y-connector Narus devices. Basically these would duplicate the data coming across the Internet—one set of packets would go the normal route, the other set would go to NSA facilities. There, they collect all the data coming in through fiber optics, reassemble all the data packets into useable information-- emails, file transfers, etc. -
A Worldwide Survey of Encryption Products
A Worldwide Survey of Encryption Products February 11, 2016 Version 1.0 Bruce Schneier Berkman Center for Internet & Society Harvard University [email protected] Kathleen Seidel Independent Researcher [email protected] Saranya Vijayakumar Harvard College [email protected] Introduction Data security is a worldwide problem, and there is a wide world of encryption solutions available to help solve this problem. Most of these products are developed and sold by for-profit entities, although some are created as free open-source projects. They are available, either for sale or free download, all over the world. In 1999, a group of researchers from George Washington University attempted to survey the worldwide market for encryption products [HB+99]. The impetus for their survey was the ongoing debate about US encryption export controls. By collecting information about 805 hardware and software encryption products from 35 countries outside the US, the researchers showed that restricting the export of encryption products did nothing to reduce their availability around the world, while at the same time putting US companies at a competitive disadvantage in the information security market. Seventeen years later, we have tried to replicate this survey. • • • • • • • • • A Worldwide Survey of Encryption Products • Feb 2016, v 1.0 1 Findings We collected information on as many encryption products as we could find anywhere in the world. This is a summary of our findings: • We have identified865 hardware or software products incorporating encryption from 55 different coun- tries. This includes 546 encryption products from outside the US, representing two-thirds of the total. Table 1 summarizes the number of products from each country. -

Cryptoparty Handbook Copyleft Dear friends, scientists & scholars, Today we’ll reclaim our privacy and improve browsing experience step-by-step. There is a diference between protecting your grandma sharing cake recipes, and a human rights activist in a hostile country. Your granny might not be the right person to sell a prepaid SIM & burner-phone to. An activist might consider the below steps entry-level basics, even dangerous if not tailored to the individual. But we all need protection. Even more so if you assume that «you got nothing to hide». «Arguing that you don’t care about the right to privacy because you have nothing to hide is no diferent than saying you don’t care about free speech because you have nothing to say.» – Edward Snowden Those with nothing to hide still like curtains in their bedroom and prefer public restrooms equipped with locks minus the CCTV cameras.

Bachelor Thesis
Bachelor thesis Implementation and Analysis of OpenPGP Functionality via NFC Author: Supervisor: Philipp Jakubeit Erik Poll 0814881 Pim Vullers [email protected] Joeri de Ruiter July 13, 2012 This thesis explains how users of smartphones can send and receive se- cure e-mails. Securing e-mails is done with Pretty Good Privacy (PGP) a standard for signing and encrypting e-mails. To sign an e-mail, a private key is needed. This private key gets stored on a smartcard, the OpenPGP Java Card, which can be connected to the smartphone using near field communi- cation (NFC). The process of signing is done by touching the smartphone with the smartcard. The results of this research are an implementation of PGP functionality using NFC on a smartphone and a detailed comparison of usability, security and performance with an existing on-phone implemen- tation of PGP. It was possible to create an implementation and to show that the smartcard option is more secure and faster than the on-phone option. The only category in which it does not rank first is usability.
