Minimizing Information Leakage under Padding Constraints. (arXiv:2209.04379v1 [cs.CR])

An attacker can gain information of a user by analyzing its network traffic.
The size of transferred data leaks information about the file being transferred
or the service being used, and this is particularly revealing when the attacker
has background knowledge about the files or services available for transfer. To
prevent this, servers may pad their files using a padding scheme, changing the
file sizes and preventing anyone from guessing their identity uniquely. This
work focuses on finding optimal padding …
