ImpactHO: Importance-Aware KV Cache Transfer for Multi-User Edge LLM Handover
Minwoo Kim, Soochang Song, Namyoon Lee +2
Edge LLMs must preserve inference continuity when a user hands over between edge nodes, requiring key-value (KV) cache transfer to the target node. However, simultaneous handovers…
Mutual Information Minimization for Side-Channel Attack Resistance via Optimal Noise Injection
Jiheon Woo, Donggyun Ryu, Daewon Seo +4
Side-channel attacks (SCAs) pose a serious threat to system security by extracting secret keys through physical leakages such as power consumption, timing variations, and electroma…
FibQuant: Universal Vector Quantization for Random-Access KV-Cache Compression
Namyoon Lee, Yongjune Kim
Long-context inference is increasingly a memory-traffic problem. The culprit is the key--value (KV) cache: it grows with context length, batch size, layers, and heads, and it is re…
Unequal Error Protection for Digital Semantic Communication with Channel Coding
Seonjung Kim, Yongjeong Oh, Yongjune Kim +2
This paper investigates unequal error protection (UEP) in digital semantic communication, where semantically important bits require substantially higher reliability than less criti…
Code-Weight Sphere Decoding
Yubeen Jo, Geon Choi, Yongjune Kim +1
Ultra-reliable low-latency communications (URLLC) demand high-performance error-correcting codes and decoders in the finite blocklength regime. This letter introduces a novel two-s…
Robust Deep Joint Source Channel Coding for Task-Oriented Semantic Communications
Taewoo Park, Eunhye Hong, Yo-Seb Jeon +2
Semantic communications based on deep joint source-channel coding (JSCC) aim to improve communication efficiency by transmitting only task-relevant information. However, ensuring r…
