A new Simplified Security Proposal for VAS-SMS Services, between TV, Radio Stations and 3G Mobile Phone Networks

Value Added Services VAS in Mobile-Phone-Networks, found its way to TV & Radio stations through the benefits from the huge audience or followers they got. Also the traditional media decides to get advantages of VAS services and consider it as a new revenue source. The traditional TV & Radio stations and the mobile phone network based on 3G technologies and beyond, both get dramatic changes by the new information technologies. So the partnership between the mobile-phone-networks and the traditional-media was unavoidable. The contribution of the third party which called MVAS (mobile value added service providers) companies that works between the mobile-phone-networks and the traditional media as a linkage ring station, for both main partners. The previous three parties try to get there share from the revenue of the VAS-SMS service. This paper suggest a new proposal based on excluding the role of MVAS companies by designing and implementing a New-SMS-Signature System, as a new Message Authentication Code MAC mechanism, that guaranties the Authentication & the Integrity criteria concerned with SMS flows between the traditional TV & Radio stations and the mobile phone network company. The target is to overcoming the security threats between the main two partners, without the need for a third part as MVAS companies, taking the Iraqi Media Network (IMN) as a case study.
