PEO-Store: Delegation-Proof Based Oblivious Storage With Secure Redundancy Elimination

2024 · IEEE Transactions on Dependable and Secure Computing

Recently, Oblivious Storage has been proposed to prevent privacy leakage from user access patterns, which obfuscates and makes it computationally indistinguishable from the random sequences by fake accesses and probabilistic encryption. The same data exhibits …

FastCache: Optimizing Multimodal LLM Serving through Lightweight KV-Cache Compression Framework

2025 · arXiv (Cornell University)

Multi-modal Large Language Models (MLLMs) serving systems commonly employ KV-cache compression to reduce memory footprint. However, existing compression methods introduce significant processing overhead and queuing delays, particularly in concurrent serving scenarios. We present \texttt{FastCache}, a …
