| Mar 13, 2021 at 17:59 | comment | added | kelalaka | I would like to mention that, in modern cryptography, we consider that even the adversary has access to knowledge of the used encryption scheme, the ciphertext, and IV, it should be secure against computationally bounded adversaries. While an unknown dated QC circuit can be a solution to your problem with a huge cost, the copy is the least issue one must consider. The package lost, lack of integrity, authentication, disturb of the channel, active attacker and so on the list goes on. Also not that the physical protections are mostly protection from the cats and dogs. Do you know NSA-DHL-laptop? | |
| Mar 13, 2021 at 15:50 | comment | added | kelalaka | Is there any way to track if a ciphertext has been decypted? | |
| Mar 13, 2021 at 15:19 | comment | added | kelalaka | A digital case with temper proof? Also, there are paper PUFs that the document can't be replicated. Your question is not clear to me. What is mean to be opened? One can x-ray and reveal the internals, or more techniques. Do you want to protect the data or the envelope that contains the paper, or both? | |
