FTFA: In fact, Lenticrypt has the theoretical property that, under reasonable assumptions, there is always a near 100% probability that there exists an key in the public domain that will decrypt a given ciphertext to any desired plaintext, even if that key is not known.
Isn't that true of any cryptosystem?
EDIT: follow-up is correct; this is only true of OTP. Sorry for the noise.
- foxhill 12y agono, not at all. even with a keyspace of 2^256, the number of possible plaintexts that make sense is an infinitely small portion of all plaintexts - you can say with reasonable certainty then, that only one plaintext, combined with the the key could produce that ciphertext. the only system that has this same property (as far as i know) would be the one-time-pad. my crypto is a bit rusty, so i may be wrong..
- ikeboy 12y agoThis system can't have that property for the same reason. #desired plaintexts > #public domain keys
