3 Thursday, May 03, 2001SMPLS-Encryption of Payloads2 Overview 1. Motivation 2. Implementation 3. Testing 4. Conclusion 5. References

4 Thursday, May 03, 2001SMPLS-Encryption of Payloads3 Motivation Security The need for it :: Do I say any more ? Efficiency Underlying fast switching paradigm offered by MPLS shouldn't be compromised at the expense of providing security Proper choice of encryption Algorithm

5 Thursday, May 03, 2001SMPLS-Encryption of Payloads4 Implementation Encryption - Entire MPLS Payload Encryption Algorithm - RC4 Stream Cipher Not too “heavyweight” Relatively fast MPLS L3 L4 ……………………….. Header Encrypted

6 Thursday, May 03, 2001SMPLS-Encryption of Payloads5 Testing - Network Setup Lemondrop 129.237.127.131 Gumdrop 129.237.127.129 Spinach 129.237.127.157 Pumpkin 129.237.127.153 Potato 129.237.127.155 Ingress / EgressCoreIngress / Egress

7 Thursday, May 03, 2001SMPLS-Encryption of Payloads6 Conclusion Present implementation Hop by hop encryption across one LSP NO “dynamic” key exchange mechanism for authentication Scope for improvement by formulating a better form of key exchange Extension of IKE Possible investigation of integration into LDP No such draft yet
