The Snowden situation raises an intereting cryptograpic problem. At present, how can something be sent confidentially to Snowden?
Claim:
I have no particular political orientation. The above question is merely a cryptographic challenge. The meta assumption isis…
- You trust someone, denoted as Snowden, but Snowden does not trust anyone and you do not know any further information about Snowden, except his name or identity.
- You should be careful that someone, say FBI, might impersonate Snowden to you.
Objective:
The objective is to
How to build a global and secure communication channel between you and Snowden from scratch, without resorting to trusting any third party?
Snowden does not trust anyone at the beginning, but he wants to find someone whom he can trust, via the secure channel built (if possible) in Step 1. How is this done?
Is this possible to do by using cryptography? Is this problem well described? If not, please edit it.
For convenience, let us call this challenge the Snowden challenge. How do we model the security objectives for Snowden and you?
