Time-lock puzzles and timed-release Crypto
Our motivation is the notion of \timed-release crypto," where the goal is to encrypt a message so that it can not be decrypted by anyone, not even the sender, until a pre-determined amount of time has passed. The goal is to \send information into the future." This problem was rst discussed by Timothy May [6]. What are the applications of \timed-release crypto"? Here are a few possibilities (som...
متن کاملTime-Lock Puzzles in the Random Oracle Model
A time-lock puzzle is a mechanism for sending messages “to the future”. The sender publishes a puzzle whose solution is the message to be sent, thus hiding it until enough time has elapsed for the puzzle to be solved. For timelock puzzles to be useful, generating a puzzle should take less time than solving it. Since adversaries may have access to many more computers than honest solvers, massive...
متن کاملScalable, Server-Passive, User-Anonymous Timed Release Public Key Encryption from Bilinear Pairing
We consider the problem of sending messages into the future, commonly known as timed release cryptography. Existing schemes for this task either solve the relative time problem with uncontrollable, coarse-grained release time (time-lock puzzle approach) or do not provide anonymity to sender and/or receiver and are not scalable (server-based approach). Using a bilinear paring on any Gap Diffie-H...
متن کاملSending Message into a Deenite Future: Non-parallelizable Case
We construct a proof of membership protocol that uses log 2 t steps to prove an element to have the structure a 2 t (modn) given public values n; a; t where n is the product of two large secret primes. Such a proof serves a concrete basis of trust for a time-lock puzzle scheme and its applications in timed-release cryptography. The achieved ef-ciency expressed in log 2 t (number of modulo expon...
متن کاملUsing Timed-Release Cryptography to Mitigate Preservation Risk of Embargo Periods
USING TIMED-RELEASE CRYPTOGRAPHY TO MITIGATE PRESERVATION RISK OF EMBARGO PERIODS Rabia Haq Old Dominion University, 2008 Director: Dr. Michael L. Nelson This research defines Time-Locked Embargo, a framework designed to mitigate the Preservation Risk Interval: the preservation risk associated with embargoed scholarly material. Due to temporary access restrictions, embargoed data cannot be dist...
