Abstract
The goal of time-based cryptography is to introduce the concept of time in cryptography. As there are two distinct views on time, one is the amount of time it takes and one is the progress of time, a timed-release encryption scheme always requires a certain amount of time or a certain time period to be passed in order to be able to perform the decryption.
In this write-up, we introduce some timed-release encryption schemes based on two different approaches and propose research directions.
