Wireless Product Vulnerability Analysis

While wireless communications have become prevalent, security is a challenge due to the unique properties associated with wireless devices and the mobile environment. Conventional security approaches focus on securing the network at the link layer and above, which is insufficient for wireless communications. TRABUS is an expert on the physical layer of wireless systems where devices communicate through encoding and modulation of information into waveforms. As such, TRABUS has expertise in implementing security services, including confidentiality and authentication, at the physical layer in conjunction with traditional higher layer security methods including cryptography algorithms and security protocols. TRABUS combines this expertise with modulation forensics capabilities and the result is a trusted and assured wireless communication system.

TRABUS provides vulnerability analysis in the telecommunications domain, to include hardware and software. This includes analysis of cellular air interfaces and control messaging protocols, embedded cellular user equipment hardware architectures and processors (ARM, DSP, etc.) for all major handset OEMs products.
