An Empirical Survey on How Much Security and Privacy Customers Want in Instant Messengers
SECURWARE 2016 : The Tenth International Conference on Emerging Security Information, Systems and Technologies An Empirical Survey on how Much Security and Privacy Customers Want in Instant Messengers Thomas Paul Hans-Joachim Hof MuSe – Munich IT Security Research Group Munich University of Applied Sciences Munich University of Applied Sciences Lothstrasse 64, Munich, Germany Lothstraße 64, Munich, Germany e-mail: [email protected] e-mail: [email protected] Abstract— Instant messengers are popular communication developers of future instant messengers to decide on tools used by many people for everyday communication, as security features to implement. well as for work related communication. Following the This paper is structured as follows: Section II discusses disclosure of a massive surveillance system by Edward related work. Section III presents the design of the user Snowden, many users became aware of the risks of unsecure survey. Section IV discusses in detail the findings of the communication. Users increasingly ask for secure communication. However, unsecure instant messengers are still user survey. Section V presents the features of an ideal popular nowadays. This could be due to the fact, that, besides instant messenger fulfilling all the user preferences the large number of available instant messengers, no instant identified by the survey. A market simulation is used to messenger fully satisfies the users preferences. To research the show the potential of this ideal instant messenger. Section acceptance of security mechanisms in instant messengers, this VI summarizes the findings of the paper. paper presents an evaluation of user preferences for secure instant messengers.

Investigating Mobile Messaging Security
Technische Universitat¨ Munchen¨ Department of Informatics Interdisciplinary Project in Electrical Engineering Investigating Mobile Messaging Security Elias Hazboun Technische Universitat¨ Munchen¨ Department of Informatics Interdisciplinary Project in Electrical Engineering Investigating Mobile Messaging Security Untersuchung von Mobile Messaging Sicherheit Author Elias Hazboun Supervisor Prof. Dr.-Ing. Georg Carle Advisor Dr. Matthias Wachs, Quirin Scheitle Date April 27, 2016 Informatik VIII Chair for Network Architectures and Services Abstract In this report we document our work in analyzing the security of a selection of mobile messaging apps. Focusing on network based security, we studied traffic generated by the apps to gain an understanding of the current state of applying encryption and authentication protocols. Our findings show a positive trend in security with developers steadily improving security with newer app updates partly due to the increased scrutiny from the community and academia. Although not all apps analyzed had perfect state of the art security properties, none have shown any major vulnerabilities exploited by normal adversaries. It was also evident that only one app - namely TextSecure - is using the industry standard TLS for server-client authentication and security while others have opted for custom made protocols and algorithms.

Smart Reply Feature ` 01-Feb-2018
SMART REPLY FEATURE ` 01-FEB-2018 Google announced that it is now rolling out the Smart Reply feature to messaging app Android Messages. The AI-based Smart Reply feature was launched with GooglePHISHING Allo back in September 2016. It will be available only for Project Fi users currently, with no timeline on a wider rollout. Google will require access to your SMS history to help it generate intelligent responses. The announcement was made through a tweet on Project Fi's official Twitter account. Smart Reply, launched with Google Allo, automatically suggests responses to messages that you have received. It provides contextual replies by analysing the recent message in the thread.PHISHING It can be turned off by going into Settings in Android Messages, under Smart Reply. The feature currently works with Google Allo, Gmail, Google Assistant, and, now, Android Messages - but the last as we mentioned is only for Project Fi users. Notably, this addition of Smart Reply to Android Messages comes a week after a teardown of Google's Gboard beta APK revealed that the Smart Reply intelligent suggestions are coming to the Gboard app on Android. The keyboard is expected to offer phrase-length suggestions in the topmost row. Thanks to the upcoming integration, the feature will work on wide variety of apps, negating the need for third-party app developers to bring Smart Reply support or similar features on their offerings. Apart from first party apps like Allo, Android Messages, and Hangouts, the feature was also spotted working on Facebook, Messenger Lite, WhatsApp, Facebook Messenger, and Tencent's platforms. -

Good to see you. Steve Gibson: Hey, Leo. Great to be with you again. And we have largely, as expected, a follow-up to last week's blockbuster theory of how PRISM works, as I expected. Actually I probably had double the number of email that I normally pull from the mailbag, which would have only been in half of the period of time. -
