I'm not sure if what I'm asking is even a valid question but here goes.
Would it be possible to add a mechanism to an encryption algorithm that would mean it had to be a certain time of the day or a certain day of the year for the encryption to be able to be decrypted.
To Clarify, It should only be decryptable at a certain time eg
- 4th February or
- 11.23 am
- or between 1 and 2 pm
working in a similar way to a time clock on a bank safe.
Obviously this would require encrypted access to an internet timeserver to ensure an unspoofed time signal.
- Does this make an sense?
- Would it be possible?
- What would the mechanism be?
I asked this on stackexchange.com but this seems a better place.
