Recently, mobile security has garnered considerable interest in both the research community and industry due to the popularity of smartphones. The current smartphone platforms are open systems that allow application development, also for malicious parties. To protect the mobile device, its user, and other mobile ecosystem stakeholders such as network operators, application execution is controlled by a platform security architecture. This book explores how such mobile platform security architectures work. We present a generic model for mobile platform security architectures: the model illustrates commonly used security mechanisms and techniques in mobile devices and allows a systematic comparison of different platforms. We analyze several mobile platforms using the model. In addition, this book explains hardware-security mechanisms typically present in a mobile device. We also discuss enterprise security extensions for mobile platforms and survey recent research in the area of mobile platform security. The objective of this book is to provide a comprehensive overview of the current status of mobile platform security for students, researchers, and practitioners.

Personal mobile devices like smartphones and tablets are ubiquitous. People use mobile devices for fun, for work, and for organizing and managing their lives, including their finances. This has become possible because over the past two decades, mobile phones evolved from closed platforms intended for voice calls and messaging to open platforms whose functionality can be extended in myriad ways by third party developers. Such wide-ranging scope of use also means widely different security and privacy requirements for those uses. As mobile platforms gradually opened, platform security mechanisms were incorporated into their architectures so that the security and privacy requirements of all stakeholders could be met. The time is therefore right to take a new look at mobile platform security, which is the intent of this monograph. The monograph is divided into four parts: firstly, the authors look at the how and why of mobile platform security, and this is followed by a discussion on vulnerabilities and attacks. The monograph concludes by looking forward and discussing emerging research that explores ways of dealing with hardware compromise, and building blocks for the next generation of hardware platform security. The authors have intended to provide a broad overview of the current state of practice and a glimpse of possible research directions that can be of use to practitioners, decision makers, and researchers. The focus of this monograph is on hardware platform security in mobile devices. Other forms of Security, such as OS Security, are briefly covered, but from the perspective of motivating hardware platform security. Also, specific high-level attacks such as jail-breaking or rooting are not covered, though the basic attacks described in Part III can, and often are, used as stepping stones for these high-level attacks.

An invaluable reference discussing the Generic Authentication Architecture (GAA), its infrastructure, usage and integration into existing networks Cellular Authentication for Mobile and Internet Services introduces the reader into the field of secure communication for mobile applications, including secure web browsing with a phone or PC, Single Sign-On (SSO), mobile broadcast content protection, secure location services, etc. The book discusses the Generic Authentication Architecture (GAA) of the mobile standardization body 3rd Generation Partnership Project (3GPP) and its American counterpart 3GPP2 in full detail and with all variants. It explains the usage of GAA by various standardization bodies and standardized applications, and also looks at a number of non-standardized ones, such as secure remote login to enterprise environment and card personalization. Cellular Authentication for Mobile and Internet Services: Describes the usage of the generic authentication architecture (GAA) by various standardization bodies and standardized applications, covering mobile broadcast / multicast service security, Single Sign-On, HTTPS (i.e. secure web browsing), secure data access, secure location services, etcProvides guidance on how to integrate the generic authentication into existing and future terminals, networks and applicationsExplains the functionality of the application security in general as well as on application developer levelDescribes various business scenarios and related security solutions, and covers secure application implementation and integrationBrings together essential information (currently scattered across different standardization bodies) on standards in one comprehensive volume This excellent all-in-one reference will provide system and protocol designers, application developers, senior software project managers, telecommunication managers and ISP managers with a sound introduction into the field of secure communication for mobile applications. System integrators, advanced students, Ph. D. candidates, and professors of computer science or telecommunications will also find this text very useful.
