mVoIP Service attack and authentication mechanism on a Smart work device

Mobile VoIP(mVoIP) Service on Smart work device provides both wide-area (cellular) access and local-area technology for Voice over IP services with a smart phone. Therefore, we should analyze the service security threat to solve security vulnerability of the SIP base mVoIP service in a wireless smart work environment. However, new problems and service vulnerabilities have been found on mVoIP services. In this paper, we examined the weaknesses about additional service provided in the commercial mVoIP network. In addition, we presented a possible authentication mechanism using voice data on mobile VoIP service.
