Defense scheme for the world state based attack in Ethereum by Zhen GAO, Dongbin ZHANG, Xiao TIAN

“…Ethereum is taken as the representative platform of the second generation of blockchain system.Ethereum can support development of different distributed applications by running smart contracts.Local database is used to store the account state (named world state) for efficient validation of transactions, and the state root is stored in the block header to guarantee the integrity of the state.However, some researches revealed that the local database could be easily tempered with, and attackers can issue illegal transactions based on the modified account state to obtain illegitimate benefits.This world-state based security problem was introduced, and the preconditions for attack were analyzed.Compared with the two common security threats under the PoW (proof of work) consensus, it was found that when the attacker controls the same mining computing power, the world-state based attack brought higher risk, and the success rate approached 100%.In order to deal with this threat, a practical scheme for attack detection and defense was proposed accordingly.The secondary verification and data recovery process were added to the Ethereum source code.The feasibility and complexity of the proposed scheme was evaluated with single-machine multi-threading experiments.The proposed scheme improves Ethereum’s tolerance to malicious tampering of account state, and is applicable to other blockchain platforms applying local database for transaction validation, such as Hyperledger Fabric.In addition, the time and computational overhead brought by the proposed scheme are not prominent, so it has good applicability and induces acceptable impact on the performance of original system.…”

Damage on a Solid–Liquid Interface Induced by the Dynamical Behavior of Injected Gas Bubbles in Flowing Mercury by Hiroyuki Kogawa, Takashi Wakui, Masatoshi Futakawa

“…Detailed observation and numerical analyses revealed that the microscopic pressure emitted from the gas bubbles contracting is sufficient to form pit damage, i.e., the directions of streak-like defects which are formed by connecting the pit damage coincides with the direction of the gas bubble trajectories, and the distances between the pits was understandable when taking the natural period of gas bubble vibration into account. …”

Key public verifiable MA-CP-ABE scheme based on aggregatable PVSS and consortium blockchain by JING Xu, JIANG Yan

“…A key public verifiable MA-CP-ABE scheme was proposed based on a consortium blockchain, ensuring the trustworthiness of verification parameters through the consortium blockchain and achieving automated verification via smart contracts. The analysis of correctness, confidentiality, robustness, and liveness indicates that when the total number of AA is <italic>n</italic>, the threshold value is <italic>t</italic>, and the number of malicious AA is not more than<italic> t</italic>-1, the scheme can ensure the correct distribution of attribute private keys, and the communication overhead complexity of the system master key initialization is <italic>O</italic>(<italic>tn</italic>).…”

Viscosity Methods of Asymptotically Pseudocontractive and Asymptotically Nonexpansive Mappings for Variational Inequalities by Xionghua Wu, Yeong-Cheng Liou, Zhitao Wu, Pei-Xia Yang

“…Let {𝑡𝑛}⊂(0,1) be such that 𝑡𝑛→1 as 𝑛→∞, let 𝛼 and 𝛽 be two positive numbers such that 𝛼+𝛽=1, and let 𝑓 be a contraction. If 𝑇 be a continuous asymptotically pseudocontractive self-mapping of a nonempty bounded closed convex subset 𝐾 of a real reflexive Banach space with a uniformly Gateaux differentiable norm, under suitable conditions on the sequence {𝑡𝑛}, we show the existence of a sequence {𝑥𝑛}𝑛 satisfying the relation 𝑥𝑛=(1−𝑡𝑛/𝑘𝑛)𝑓(𝑥𝑛)+(𝑡𝑛/𝑘𝑛)𝑇𝑛𝑥𝑛 and prove that {𝑥𝑛} converges strongly to the fixed point of 𝑇, which solves some variational inequality provided 𝑇 is uniformly asymptotically regular. …”
