Beyond Vector Hiding: Breaking and Mitigating Shared-Direction Weight Obfuscation in TEE-Offloaded Large Language Models
Menghui Zhang, Aoying Zheng, Guoxiao Liu +4
Trusted Execution Environment (TEE)-shielded partitioning of Large Language Models (LLMs) accelerates on-device inference by offloading obfuscated linear layers to an untrusted acc…
Principal ideal problem and ideal shortest vector over rational primes in power-of-two cyclotomic fields
Gaohao Cui, Jianing Li, Jincheng Zhuang
The shortest vector problem (SVP) over ideal lattices is closely related to the Ring-LWE problem, which is widely used to build post-quantum cryptosystems. Power-of-two cyclotomic…
Solving the Decision Principal Ideal Problem with Pre-processing
Jincheng Zhuang, Qi Cheng
The principal ideal problem constitutes a fundamental problem in algebraic number theory and has attracted significant attention due to its applications in ideal lattice based cryp…
Syndrome decoding meets multiple instances
Haoxuan Wu, Jincheng Zhuang
The NP-hard problem of decoding random linear codes is crucial to both coding theory and cryptography. In particular, this problem underpins the security of many code based post-qu…
LWE from Non-commutative Group Rings
Qi Cheng, Jun Zhang, Jincheng Zhuang
The Ring Learning-With-Errors (LWE) problem, whose security is based on hard ideal lattice problems, has proven to be a promising primitive with diverse applications in cryptograph…
