Protecting applications with transient authentication

Mark D. Corner, Brian D. Noble
2003 Proceedings of the 1st international conference on Mobile systems, applications and services - MobiSys '03  
Such persistent authentication is inappropriate for mobile and ubiquitous systems, where associations between people and devices are fluid and unpredictable.  ...  Applications can be protected transparently by encrypting in-memory state when the user departs and decrypting this state when the user returns.  ...  Acknowledgements The authors wish to thank Peter Chen and Peter Honeyman, for many valuable conversations about this work.  ...

The Influence of Architectural Styles on Security, Using the Example of a Certification Authority [article]

Michael Tänzer
2014 arXiv   pre-print
So integrating security concerns early in the design process seems a promising approach for increasing the security of the resulting system.  ...  The requirements for the system are gathered and multiple designs according to different architectural styles are drafted and evaluated using a risk evaluation method.  ...  As the services also are responsible for persisting their data, they can't be deployed on multiple machines without some preparation.  ...
