I have not yet convinced myself that a time-release information device is impossible....

Does there exist a storage device that, due to _dynamics_ (or other factor), prevents the total contents being read in one instance?

Bubble memory device? Torsion wire memory device?

The only one I've been able to think of (from this thread on sci.crypt several years ago) was a message, e.g., PGP encrypted with two different public keys K1 and K2: E(K1, E(K2, E(K1, E(K2, ..., E(K1, X)...)))) with private key 1 here on Earth and private key 2 a reasonable distance away -- e.g., Mars. The time it takes to decrypt this *can* be lower-bounded, assuming the private keys remain secret. - Carl +--------------------------------------------------------------------------+ |Carl M.
