I want to know what attack am I exposed to if I implement one of the two method. I'm pretty sure both of them are not 100% fool-proof and both of them are expose to traffic-analysis attack if I do sent the files through the internet. I want to know a specific threat or way that can allowed me to comprehend which one is better for my scenario which is the most secure one.
Right now, I just confuse because both of them expose to certain attack. And if I want to make a decision according to efficiency surely "with compression" would have won but my focus is mainly on security of the data.
The flaws of compression is that it can expose an information but to what extend. Does it make the security of my encryption become penetrable (if it is that easy to decrypt). That's all from me. Thanks in advance.
