  1. Data Control Application for Telecommunication Operators Students: Yuri Manusov, Boris Umansky, Yevgeni Fishman Academic Advisor: Prof. Yuval Alovich Industry Advisor: Yuri Granovski With Motorola, Israel

  2. Problem definition: • More and more telecommunication providers use VoIP infrastructure. • Eavesdropping to someone conversation is very simple (requires connection to internet and packet capture software). • Spam over the phone becomes more and more popular. • Business clients are interested in more secured telecommunication services. • Telecommunication providers interested to supply them with these services.

  3. Available Solutions: • Nowadays SIP(Session Initiation Protocol) is widely used for VoIP. • The caller sends a request to SIP server with the callees nickname, receives its IP as a response and establishes P2P communication between two hosts. Callees nickname Callees IP Conversation

  4. Available Solutions(cont.): • There are couple solutions for VoIP security available nowadays. • SRTP and ZRTP protocols are both secured type of RTP (Real-time Transport Protocol), which is the 4th layer in VoIP. • Main problems of these protocols: • Clients shall perform initial master key exchange. • Not all SIP clients supports these protocols. • Special hardware for every client required to create strong master key. • There is no well known service for communication control management.

  5. Project Requirements • [R1] Rule Based Authorization • The system shall provide specified authorization of users according to the rules kept in the configuration storage. • Rules shall be user based or time based. • [R2] Security • The system shall provide clients with the ability to establish IPSec secured session, or an unsecured session, according to the rules kept in the configuration storage.

  6. Project Requirements(cont.) • [R3] Dynamic Configuration • The system shall provide users with the ability to control their own configurations, more specifically, the rules of the authorization, and the rules of the security. • The system shall provide the users with GUI in order to do that. • [R4] Communication History Storage: • The system shall store all the history of the communications that took place.

  7. Our Project: Telecommunication Provider Server JBOSS Server JSLEE Server Communication Control Application Data Storage SIP Request Event Control Rules Manager SIP Resource Adapter HTTP Host 2 IP Pre-shared Key SIP Request Pre-shared Key IP Host 2 IP Host 1 SIP Client Enabler Enabler SIP Client IPSec Communication Configuration Configuration IPSec Module IPSec Module

  8. Our Project(cont.) • Project Scope: • Communication Control Application: JSLEE service that provides Rules Based authorization and communication history storage as described in requirements [R1],[R4]. • Enabler: Application, running on the host station, that will configure IPSec communication between clients [R2]. • Data Storage: SQL based DB to store all the required data [R3],[R4]. • GUI for Configuration Control Application [R3]. • Project uses: • SIP client, SIP RA and SLEE server provided by Mobicents, IPSec module provided by OS. • Out of Scope: • Registration of users. • Communication between SIP Server and Communication Control Application.
