1 Layer 1 Encryption in WDM Transport Systems Dr. Henning Hinderthür, PLM

2 Security in Telco "What last year's revelations showed us was irrefutable evidence that unencrypted communications on the internet are no longer safe. Any communications should be encrypted by default Edward Snowden - Guardian Interview, Moscow July

4 Data Center Environment & Security Physical Access to the Data Center APPS APPS 4

5 Data Center Environment & Security Hardware Security APPS APPS 5

6 Data Center Environment & Security Software Security APPS APPS 6

7 Data Center Environment & Security and what about the Fiber Connection? APPS APPS 7

8 Fiber Optic Networks Tapping Possibilities Where to get access? Street cabinet Splice boxes / cassettes (Outdoor / Inhouse) How to get access? Y-Bridge for service activities Fiber Coupling device There are multiple ways to access fiber 8 Protocol Analyzer

9 Encryption What is Key? Highest level of security Speed - Low Latency 100% Throughput No Jitter Role Based Management (Multi Tenant Management for Carriers) Encryption on the lowest possible layer 9

10 Encryption Basics Key Lengths Magnitude Number of grains in 1 m 3 sand from the beach 2 40 Number of atoms in a human body 2 92 Number of atoms in the earth Number of atoms in the sun Number of atoms in the Milky Way Number of atoms in the universe AES

11 High Speed Encryption Modes Point-to-Point Protocol/ I/F agnostic (Ethernet, FC, IB, Sonet/SDH) Integrated Solution with lowest latency Bulk Mode (0 Bytes) Hop-by-Hop only Ethernet only Overhead creates latency and throughput issues MacSec +32 Bytes Cisco TrustSec +40 Bytes Huge overhead IP VPN Services Cisco Nexus Cisco Overlay Transport Virtualization (OTV) +82 Bytes 11

18 Encryption Management & Operations 18

19 Data Center Networks Encryption Management for Private Networks Scenario 1 - User of encryption is the operator of equipment LAN FSP EM or LCT/CLI DCN FSP NM Server FSP NM Clients 3 rd Party NE 3 rd Party NE 3 rd Party NE Crypto Manager running on FSP NM 19

20 Data Center Networks Encryption Management for Private Networks Scenario 2 - Encryption user does not own the network LAN WWW. FSP NM Server FSP NM Clients GUI Server running NM client apps DCN Customer A 3 rd Party NE 3 rd Party NE 3 rd Party NE Crypto Manager running on GUI Server 20

21 Crypto Management Management Levels Provided Operational management Deals with all operational aspects (FCAPS) User access is handled on the NCU Security management Control of all security relevant activities Separated from operational management Access control handling on the AES Muxponder not on the NCU Security relevant activities are performed using the security relevant credentials ROOT users have no access to security management 21

22 Encryption over OTN Networks 22
