DESCRIPTION:Gwangbae Choi\nEDIC candidacy exam\nExam president: Prof. Arje
 n Lenstra\nThesis advisor: Prof. Serge Vaudenay\nCo-examiner: Prof. Viktor
  Kuncak\n\nAbstract\nThe goal of time-based cryptography is to introduce t
 he concept of time in cryptography. As there are two distinct views on tim
 e\, 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 d
 ecryption.\nIn this write-up\, we introduce some timed-release encryption 
 schemes based on two different approaches and propose research directions.
