Upper bound probability of double spend attack on SPECTRE

Proof-of-Work (PoW) is a Sybil control mechanism adopted in blockchain-based cryptocurrencies. It prevents the attempt of malicious actors to manipulate distributed ledgers. Bitcoin has successfully suppressed double-spending by accepting the longest ...

The blockchain technology has emerged as an attractive solution to address performance and security issues in distributed systems. Blockchain's public and distributed peer-to-peer ledger capability benefits cloud computing services which require ...

The trust execution environment (TEE) provides a safe region, also known as a secret enclave, for executing private programs that need protection. This work proposed a cross-process exploitation scheme for conducting the cache side-channel attack,...
