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.

Connectivity-enabled phones feature access to the Internet and networking through multiple access technologies such as 3G or Wi-Fi, as well as personal communication means such as Bluetooth® and Near Field Communication (NFC). Among these, enterprise-type phones that enable push e-mail access and office applications have proved xtremely popular. They give users a “work anywhere” ability that requires a secure link to their workplace applications through virtual private networking (VPN), secure storage of their data and remote management of the phone by the IT department. Company IT departments are often wary of enabling connectivity access to their networks, fearing that the handsets could carry malware and create attacks from within the network when used on company premises.
