1. CDMA device till PCF • CDMA uses spread spectrum technology

• CDMA uses the standardized CAVE(Cellular Authentication and Voice Encryption) algorithm to generate a 128-bit

sub-key called the “Shared Secret Data” (SSD) to encrypt data packets over the air interface

2. PCF till PDSN • Traffic is routed over secure Tata DOCOMO private data backbone.

• The traffic is tunneled from PCF till PDSN using standard GRE tunneling protocol

3. PDSN till LNS • Each PPP session is authenticated by AAA server at PDSN

• Further tunneled till LNS using layer-2 L2TP tunnel protocol

• PDSN & LNS authenticate each other using PAP/CHAP protocols

4. LNS till customer site • The final network segment: secure MPLS link between LNS located Tata DOCOMO PE router & customer

5. Optional and Additional Security (IPSec) • Additional security layer can be built using IPSEC between Customer’s server and Netaxcess router
