This might not be the right place. But, I adore your research works Dr. Lindell :D

comment Machine readable, user non-readable - XML file
IMO, the best persons to ask this, are the software developers of EventGhost. Sorry, I don't think this is by any means related to topics covered here.

comment Vigenère cipher frequency analysis not working
The problem is due to the small ciphertext you've used. When using something like 12 letter length key, what you have for frequency analysis would be 12th the amount of the whole ciphertext. Thus too small for analysis. Use a sample with 12k letters and then assess the results.

comment Perfectly secret cipher can leak about the key?
Perfectly secure Public Key encryption is impossible. Because in the theory of computer science it has been proven that any turing machine (even a quantum turing machine) that does not "throw away information" is reversible. An encryption algorithm should not throw away information since the information is required for decryption. As a result, in case of public key encryption we only stand against a computationally bounded attacker. And, the only possible security is computational security.

comment As a cryptographer, what are the things I should care about in my implementation of pairing functions?
I wonder is there a problem with my explanation of question or it is not a matter of interest for the majority of this website's users. I expected much more interested and experienced users in this field. I can't believe there was no answer during these days. (And... am I allowed to post this type of comments?)
