| Abstract | With the advent of LTE another technology is gaining momentum in mobile communication, viz. Voice-over-IP (VoIP). While LTE provides state-of-the-art security features such as confidentiality, integrity, and authenticity, non-repudiation of voice communication over LTE is not addressed. At the same time the utilization of mobile phone devices for business communication is already common practice. However, applications supporting specific business requirements, such as the confirmability of statements made in a phone call, are missing. VoIP Signatures is a recognized concept to achieve both non-repudiation for VoIP calls as well as integrity protection against the manipulation of recorded conversations. We present the integration of this concept with a VoIP client running on a mobile device. The implementation concept has been optimized for applicability on standard smartphones with regard to given characteristics such as processing power limitations. The implementation concept is introduced and the performance has been evaluated, resulting in a promising statement regarding the applicability of our approach on future mobile devices providing Voice-over-LTE functionality. |
