Trust Security and Identity Management

Trust Security

As wireless networks become more and more distributed, new cyber security threats are emerging and endpoint protection is becoming increasingly necessary for an evolved security architecture for these distributed wireless networks. Unprotected network edge components are susceptible to malicious attacks and will require enhanced security. These edge devices are not protected by the typical garden wall security afforded to other network nodes, leaving them vulnerable to multiple attack vectors.

Additionally, as users become more dependent on the use of mobile devices (e.g. tablet computers and smart phones) and Internet technologies to access data and services, the value of trust security for mobile systems must also keep pace with the increased threats to user data and secure use of Internet services.

InterDigital is developing technologies which leverage the work carried out in industry and academia on trust security to protect devices from malicious attack such as malware and viruses. We have evolved the work carried out in the Trusted Computing Group (TCG) and adapted it for wireless communications systems in a practical manner, which reduces the burden on network operations in terms of bandwidth consumed and the processing burden on the network authentication, authorization and device management functions.


Identity Management

One of the challenges in the growing use of online services is the management of digital user identities. Users are overwhelmed with the number of identities and passwords they need to remember and are resorting to mechanisms which compromise their security and privacy. Additionally, as they use more and more mobile Internet services, the scale of the threats arising from poorly implemented identity management (IdM) systems include identity theft, phishing, fraud and lack of privacy.

Most services implement proprietary IdM systems where a password based mechanism is the most widely used method for user authentication. While Federated Identity and Single Sign-On systems address the issue of users having to maintain multiple credentials, they don’t address ease of use while maintaining the security. InterDigital is developing innovative IdM technologies which leverage the latest work in biometrics and multi-factor security while providing users with a secure ease of access to their data and Internet services. InterDigital’s Smart OpenID technologies enable users to gain secure “one-click” access to wireless Internet services with a convenience and grade of security tied to smart cards and the authentication systems of mobile network operators.
