Software Development Kit SIM Subscriber Identity Module VM Virtual Machine W3C World Wide Web Consortiu 5 Introduction In some situations web applications require a higher level of authentication. A way to achieve this is using smart cards which can enhance the security of a web application. This concept has been used on desktop computers for many years now. Non-mobile devices have the room for extra peripherals such as smart card readers. In addition they do not suffer from the lack of computing power as mobile devices do. Furthermore the desktop operating system market is somewhat established, meaning that there are only a few big contenders – Microsoft Windows, Apple Macintosh and various Linux distributions. (NetMarketShare, 2011) On the other hand the mobile device operating system market is more scattered. This makes it difficult to develop a unified method of accessing a local smart card and using it as a means of authentication on a mobile device. Description of the problem Currently service providers will have to provide platform specific software to enable smart card use over an IP based network. Developing an application for each mobile platform is not cost effective because it requires managing different sets of software and possibly having a 6 greater number of developers in the team. To reduce the costs the software on mobile platforms should

  • Ten Steps to Smartphone Security
    Ten Steps to Smartphone Security Smartphones continue to grow in popularity and are now as powerful and functional as many computers. It is important to protect your smartphone just like you protect your computer as mobile cybersecurity threats are growing. These mobile security tips can help you reduce the risk of exposure to mobile security threats: 1. Set PINs and passwords. To prevent unauthorized access to your phone, set a password or Personal Identification Number (PIN) on your phone’s home screen as a first line of defense in case your phone is lost or stolen. When possible, use a different password for each of your important log-ins (email, banking, personal sites, etc.). You should configure your phone to automatically lock after five minutes or less when your phone is idle, as well as use the SIM password capability available on most smartphones. 2. Do not modify your smartphone’s security settings. Do not alter security settings for convenience. Tampering with your phone’s factory settings, jailbreaking, or rooting your phone undermines the built-in security features offered by your wireless service and smartphone, while making it more susceptible to an attack. 3. Backup and secure your data. You should backup all of the data stored on your phone – such as your contacts, documents, and photos. These files can be stored on your computer, on a removal storage card, or in the cloud. This will allow you to conveniently restore the information to your phone should it be lost, stolen, or otherwise erased. 4. Only install apps from trusted sources.

The first publicly available smartphone running Android, the HTC Dream, was released on October 22, 2008. The user interface of Android is based on direct manipulation, using touch inputs that loosely correspond to real-world actions, like swiping, tapping, pinching and reverse pinching to manipulate on-screen objects. Internal hardware such as accelerometers, gyroscopes and proximity sensors are used by some applications to respond to additional user actions, for example adjusting the screen from portrait to landscape depending on how the device is oriented.

Organizations are building or porting their applications to mobile platforms, so users are increasingly accessing the same data with mobile as with their laptops. Also, organizations have increasingly implemented Bring Your Own Device (BYOD) policies to manage this trend. However, many organizations have been struggling with the increase of personal mobile devices, and don’t fully understand the security risks they may bring. There are concerns that their compact size makes them easy to lose, that they run newer operating systems that don’t
