Applying Cold War Learnings to our Daily OPSEC

At this MeetUp, Chris Campbell - a big fan of cold war history and spy tactics - will dive deep into an application he developed to take care of a small but important task: sharing secrets.

A dead drop is a method of exchanging secrets between two agents, whereby the secret is stored in a safe, predetermined location for collection, thus meaning that the two agents never have to meet and are able to maintain operational security. Where there is concern that a drop may be compromised, an additional key to decrypt the secret may be transferred using a different channel. This method was incredibly popular and effective during the cold war, and served as the inspiration for Chris' application "DeadDrop (". In fact, the inspiration for DeadDrop goes beyond the time of the cold war and into the present, realising that there is a decreasing level of trust in service providers - so also offers a "host proof" mode of operation and is open-sourced. Gone are the days of transferring secrets (e.g. credentials) in plaintext emails and texts.

This session will look into a few aspects of DeadDrop:

• A short history lesson: the inspiration for DeadDrop

• The importance of OPSEC in our daily lives

• The theory behind effective secret sharing

• Cryptography 101.

• .NET and JS cryptographic considerations

• Code breaking 101.Chris • Wed, 8:11 PM
