Modern blockchains, such as Ethereum, enable the execution of so-called smart contracts–
programs that are executed across a decentralised network of nodes. As smart contracts …

We improve key reinstallation attacks (KRACKs) against 802.11 by generalizing known
attacks, systematically analyzing all handshakes, bypassing 802.11's official …

Finding software vulnerabilities in concurrent programs is a challenging task due to the size
of the state-space exploration, as the number of interleavings grows exponentially with the …

Encryption is prevalent in many forms of modern communications. Still, wireless
communications security holds higher priority since any device can easily intercept the data …

Ethereum has officially provided a set of system-level cryptographic APIs to enhance smart
contracts with cryptographic capabilities. These APIs have been utilized in over 10% of …

Cryptographic protocols are often expected to be provably secure. However, this security
guarantee often falls short in practice due to various implementation flaws. We propose a …

符号执行技术从理论上可以全面分析程序执行空间, 但对安全协议这样的大型程序,
路径空间爆炸和约束求解困难的局限性导致其在实践上不可行. 结合安全协议程序自身特点 …

Finding software vulnerabilities in concurrent programs is a challenging task due to the size
of the state-space exploration, as the number of interleavings grows exponentially with the …

The verification of security protocol implementations is notoriously difficult and important. In
this paper, combining with the model learning using Tamarin, a formal verification tool of …

Internet of Things (IoT) is a system that consists of a large number of smart devices
connected through a network. The number of these devices is increasing rapidly, which …
