Demonstrations of some of the learning materials developed are available on the m-learning project website at www.m-learning.org. These can be viewed on a PC or on mobile devices. Learners can access materials online via the mPortal/learning management system/intelligent tutor or useoffline learning materials downloaded to the PDA/phones. We decided to offer both online and offline access in order to provide a better user experience (ie one in which minimal inconvenience and interruption is caused by disruption to, or reduced quality of, signal while learners are on the move or in remote locations). Work-in-progress learning materials have been demonstrated at many events during the project and small groups of learners have tested materials and provided feedback. Feedback from sessions in phase 2 of the project has been extremely positive and suggestions have been made for different kinds of materials that would also be useful. For example, materials for learners at UK Adult Literacy/ Numeracy Curriculum Entry levels 1 and 2 were suggested, as most of the materials developed by the project are designed for Entry level 3 and UK Adult Literacy/Numeracy Curriculum level 1 learners (ie those who have basic literacy and numeracy but need assistance to develop more comprehensive and sophisticated skills).

M-Shield mobile security technology includes a public-key infrastructure that provides a secure means to validate the authenticity and integrity of various software on the platform before execution. The M-Shield mobile security technology solution provides a state-of-the-art hardware-based AES and public-key accelerator (PKA), as well as DES/3DES, SHA and MD5 hardware accelerators. M-Shield mobile security technology hardware accelerators enhance the user experience by authentication and fast content decryption and integrity checking. The strength M-Shield mobile security technology solution infrastructure provides reduces the unauthorized use of handsets and fraud while enabling the deployment of value-added secure services. The M-Shield mobile security technology solution infrastructure provides the highest level of security to reduce the unauthorized use of handsets and fraud while enabling the deployment of value-added secure services.
M-shield mobile protection

OMAP-Vox solutions include the analog components, power management and RF devices. M-Shield mobile security technology provides the infrastructure needed to support platform-level security for the mobile device itself, as well as any high-value content transmitted or stored on the device. Safe execution of sensitive applications and secure storage of important data is enabled by a hardware-enforced secure environment. For example, secure on-chip keys(E-Fuse) are OEM-specific, one-time-programmable keys accessible only from inside the secure environment for authentication and encryption. M-Shield mobile security technology offers the industry’s leading hardware-based secure environment, embedding a secure state machine (SSM) as well as secure ROM and RAM. The SSM applies and guarantees the system’s security policy rules while entering, executing and exiting from the secure environment. Also critical to the overall protection offered by M-Shield mobile security technology is the elimination of the vulnerability of chip interconnects and DMA transfers. TI’s M-Shield mobile security technology provides the capability of the secure environment to qualify DMA transfers as secure to protect the confidentiality of sensitive high-value data (such as DRM-protected content) during their processing and transfer throughout the platform.
Security features

To support the widespread adoption of new services and to address the convergence between the mobile world and the Internet increased levels of security in handsets are essential. Theft and fraud are a constant problem in the mobile market today. Currently, IMEI/SIMLock features on handsets have been circumvented. Handsets today are a long way from the basic communication devices of the past; they have become “lifestyle” devices that include multimedia players, cameras, location devices, portable office capabilities and e-Wallet functionality. They help us perform our daily working tasks, entertain us, capture the memories we cherish and facilitate routine transactions.
As a result, a wealth of valuable data and information accumulates in our phone’s memories and needs to be protected. Multimedia-feature phones today often carry MP3 audio players, video players and mobile TV applications. Some also boast console-quality 3-D gaming platforms. All of this functionality requires digital rights management (DRM) or control access (CA) services to protect high-value content. The DRM and CA schemes are often associated with content management and protection models, such as Content Management License Administrator (CMLA) or Content Protection for Recordable Media (CPRM), that favor secure, hardwarestrengthened content protection. They are also often associated with penalty clauses to further motivate OEMs to adopt strong protection schemes.

Need for security

As mobile handsets become increasingly complex, connected and ubiquitous, the need for security on the handset has become essential. Further, the convergence between the mobile device and Internet through 3G and Wi-Fi dramatically increases the potential security threats on handsets. The vast majority of current phone security solutions are software-based, which are inherently more vulnerable to hacking, viruses and other malicious attacks than hardware solutions. Operators have traditionally wanted to protect their phone assets and make sure that the handset performs only in the ways expected on their network. This demand has led to protection mechanisms that OEMs have integrated into their handsets, complemented by other OEM-implemented secure mechanisms to further protect handsets from cloning and unwanted modifications. OEMs have now extended this hardware-based security foundation to begin addressing security requirements of applications and services running on their platforms, such as content DRM and service access protection.
Page Builder tools

The Page Builder tools within the mPortal allow learners to create and edit their own mini web pages for viewing on mobile devices (and also accessible from a desktop computer) in a password-protected environment. The pages learners create can contain a number of different elements including text, pictures, movies, animations, audio, blogs (a short version of the term ‘web log’, meaning a publicly accessible web-based journal), conversations and links to any web pages chosen by the learner. The learning management system – Intelligent Web Tutor (IWT) – includes a repository for online learning materials and learner tracking functionality. IWT includes access to an intelligent tutor system – Learner Intelligent Agent (LIA) – that selects modules for learners based on their preferences and progress to date, and a Knowledge Representation Tool (KRT), which allows tutors to create/import/export courses and modules.
