comment Brute force against computational security
-1, while the answer may be contained in here, it is not obvious. A good answer should be clear and concise.

comment Brute force against computational security
Define computationally secure. Do we have any cryptosystems that are proven computationally secure?

Why not FHE? You could do a secure 2-party computation.

comment Homomorphic Encryption: how does the equality test on ciphertexts work?
You could likely do it with some sort of interactive protocol (think Zero-knowledge proof).

comment What is the fixed point attribute of DES (when used with weak-keys)
You want an explanation of why DES has weak keys or of what the issue is with having weak keys? I'm assuming the former (as the latter should be obvious), but your question is a little unclear.

Straight up reference requests are off-topic on this site. I edited your question to make it more on-topic. If I changed your original intent, please let me know or feel free to edit yourself.

comment Perfect secrecy of a crypto system
I don't really see a question. Just a command. I.e., "prove this for me" instead of "how would I prove this". That said, I believe the latter has been explored on here at least once.
