more…a world of possibilities)

Who WANTS Secure Calling

Barack Obama (and others) – national security, public safety

Utilities – operational security, homeland security Legal – protecting confidentiality, negotiations Large Manufacturers – competitive and HR info Medical – privacy (Hippa), medical records and

messaging Financial – deal secrecy, confidentiality

6

How did BBTelsys get started?

Working with Ingate since 2003 (early adopter)– Putting the tools in place to secure networks

Respect for securing the network– Don’t let VoIP be a tempting target for hackers– The business customer expects 99.999% up-time. It is a

“mission critical application”.– Well managed IP infrastructure is essential.

Interaction with Customers – Asking the Customer “What If”

– Our strategy is to search for differentiators– Secure calling is a niche but significant unmet need

7

What Ingate Brought to Our Attention

Signaling and Media flow separately TLS/SRTP (Transport Layer Security/Secure Real

Time Protocol) could provide the right and sufficient encryption for the dynamics of VoIP application (although not widely used)

– Low Overhead– High number of small packets– Dynamics of both TLS (on signaling) and SRTP (media)

creates a high level of difficulty to crack decoding encryption

8

Flexibility of Ingate SIParators

Decrypt/encrypt both TLS and SRTP streams to and from the PBX

Decrypt/and then re-encrypt for end-to-end solutions Pass the media in its encrypted state without

decrypting

9

What’s Wrong with Most Data Encryption Technology

Developed for data, long packets The more complex the better Time delay doesn’t impact use

High Overhead Produces Delays Which Interrupts or Downgrades Voice Quality

10

What Devices Can Use TLS

Ingate’s Edge Devices TLS aware phones

– Polycom– Aastra– Snom

11

Where are Customers Vulnerable

The customer is most vulnerable to espionage at his internet connection

Most existing PBX’s do not allow for encryption

12

Confidentiality on the Internet

TLS – End-User/Carrier Results

Quality of Call Maintained, no noticeable influence or delay

Approximate Bandwidth Overhead appears quite low (but has not been measured?)

15

BBTelsys is Open for Business

BBTelsys offers TLS Test Calling Today– SIP Trunks– Hosted Plans

The Opportunity for a Reseller or End-User– Secure calling is a differentiator– Major accounts interested– Separate yourself from the competition with

BBTelsys

16

Future Secure Calling Developments

Secure solutions for the Mobile Worker– Current wireless networks frequently unsecured.

– a major worry for security conscious

– Opportunity initially with softphones to provide similar security

– Future solutions on smartphone with fixed-mobile convergence running VoIP phone (ala President’s Blackberry?)
