MURMUR: Using cross-user chatter to break collaborative language agents in groups
Atharv Singh Patlan, Peiyao Sheng, S. Ashwin Hebbar +2
Language agents are rapidly expanding from single-user assistants to multi-user collaborators in shared workspaces and groups. However, today's language models lack a mechanism for…
Real AI Agents with Fake Memories: Fatal Context Manipulation Attacks on Web3 Agents
Atharv Singh Patlan, Peiyao Sheng, S. Ashwin Hebbar +2
AI agents integrated with Web3 offer autonomy and openness but raise security concerns as they interact with financial protocols and immutable smart contracts. This paper investiga…
Scalable Fingerprinting of Large Language Models
Anshul Nasery, Jonathan Hayase, Creston Brooks +4
Model fingerprinting has emerged as a powerful tool for model owners to identify their shared model given API access. However, to lower false discovery rate, fight fingerprint leak…
Unconditionally Safe Light Client
Niusha Moshrefi, Peiyao Sheng, Soubhik Deb +2
Blockchain applications often rely on lightweight clients to access and verify on-chain data efficiently without the need to run a resource-intensive full node. These light clients…
Proof of Diligence: Cryptoeconomic Security for Rollups
Peiyao Sheng, Ranvir Rana, Senthil Bala +2
Layer 1 (L1) blockchains such as Ethereum are secured under an "honest supermajority of stake" assumption for a large pool of validators who verify each and every transaction on it…
SAKSHI: Decentralized AI Platforms
Suma Bhat, Canhui Chen, Zerui Cheng +8
Large AI models (e.g., Dall-E, GPT4) have electrified the scientific, technological and societal landscape through their superhuman capabilities. These services are offered largely…
Proof of Backhaul: Trustfree Measurement of Broadband Bandwidth
Peiyao Sheng, Nikita Yadav, Vishal Sevani +4
Recent years have seen the emergence of decentralized wireless networks consisting of nodes hosted by many individuals and small enterprises, reawakening the decades-old dream of o…
TrustBoost: Boosting Trust among Interoperable Blockchains
Peiyao Sheng, Xuechao Wang, Sreeram Kannan +2
Currently there exist many blockchains with weak trust guarantees, limiting applications and participation. Existing solutions to boost the trust using a stronger blockchain, e.g.,…
ACeD: Scalable Data Availability Oracle
Peiyao Sheng, Bowen Xue, Sreeram Kannan +1
A popular method in practice offloads computation and storage in blockchains by relying on committing only hashes of off-chain data into the blockchain. This mechanism is acknowled…
BFT Protocol Forensics
Peiyao Sheng, Gerui Wang, Kartik Nayak +2
Byzantine fault-tolerant (BFT) protocols allow a group of replicas to come to a consensus even when some of the replicas are Byzantine faulty. There exist multiple BFT protocols to…
