3. 11/18/2002IETF 553 Use of IPsec for Securing Relay Agents Messages Problem: Messages exchanged between relay agent may require protection against modification Solution: Use IPsec between relay agents and servers to authenticate source and contents Use IPsec “pairwise” between relay agents and servers Use ESP and packet authentication IPsec can be configured at same time as relay agent forwarding Pro: uses existing technology Con: requires configuration of relay agents and server, requires key management
