comment Derived Shared Key vs Distinct Keys?
What kind of replay attacks specifically? I don't see how using the shared key for authentication and encryption would open up a replay vulnerability.

comment Encryption technique performance evaluation
I don't believe you can say that all amateur encryption schemes are insecure because frankly, things like AES and Serpent are amateur in nature. You cam also make something so complicated and convoluted that it's very difficult to analyze without knowledge of the actual cipher. So, if this individual hid their cipher implementation and simply posted the ciphertext online, it's pretty likely that even the NSA would not be able to break it without a fair bit of hints. There have been amateur ciphers in the past that have not been broken by the FBI nor the NSA this way.
