zkVC: Fast Zero-Knowledge Proof for Private and Verifiable Computing
Yancheng Zhang, Mengxin Zheng, Xun Chen +5
In the context of cloud computing, services are held on cloud servers, where the clients send their data to the server and obtain the results returned by server. However, the compu…
TPU as Cryptographic Accelerator
Rabimba Karanjai, Sangwon Shin, and Wujie Xiong +8
Cryptographic schemes like Fully Homomorphic Encryption (FHE) and Zero-Knowledge Proofs (ZKPs), while offering powerful privacy-preserving capabilities, are often hindered by their…
Cross Chain Bribery Contracts: Majority vs Mighty Minority
Quang Tran, Lin Chen, Lei Xu +3
Bribery is a perilous issue in the real world, especially in an economical aspect. This fraudulence is unavoidable, and more importantly, it is more difficult to trace in case smar…
Lessons Learned from Blockchain Applications of Trusted Execution Environments and Implications for Future Research
Rabimba Karanjai, Lei Xu, Lin Chen +3
Modern computer systems tend to rely on large trusted computing bases (TCBs) for operations. To address the TCB bloating problem, hardware vendors have developed mechanisms to enab…
Private and Atomic Exchange of Assets over Zero Knowledge Based Payment Ledger
