Sending messages into the future
The idea of sending information into the future for cryptographic purposes emerged in 1993. In the last 30 years, researchers have studied different approaches to this problem and successfully designed some cryptographic primitives capable of hiding information for a fixed period of time. Their work resulted in the conception of timed-release encryption, pricing functions and verifiable delay functions. In this seminar, we will look at the many applications of timed-release encryption and at the underlying techniques that solve this seemingly impossible problem.
