Security

We propose ReShift, the first aha-moment-driven reasoning-level backdoor framework for Vision–Language Models that redirects chain-of-thought trajectories while preserving surface-level coherence.

PEKS with Keyword Search is one of the most used method to search keywords over encrypted data. However, semantic security is not preserved and dictionary attack can help attackers to guess keywords. This project solves that issue implementing PEKS and searching keywords over Bloom Filter.

While using cloud platform or any other insecure memory, attack can be made using the access pattern. Oblivious RAM is the way to hide the memory access pattern with some extra bandwidth and memory overhead. Path ORAM uses a binary tree to store all memory blocks and changes the location of the blocks repeatedly to access the whole branch for a single block.
