Certificateless public key cryptography based provable data possession scheme in edge environment
Tongxin xuebao, 2022 In the edge environment, data transmission to the cloud needs to pass through a new entity, the edge node, which makes the data security problem more complicated, the confidentiality and integrity of data are difficult to be guaranteed, and the ...

Provably Secure Metering Scheme [PDF]
, 2000 Naor and Pinkas introduced metering schemes at Eurocrypt '98 in order to decide on advertisement fees for web servers. In the schemes, any server should be able to construct a proof to be sent to an audit agency if and only if it has been visited by at least a certain number, say k, of clients.

Provable data possession scheme with authentication
Tongxin xuebao, 2016 To satisfy the requirements of identity authentication and data possession proven in the cloud application scenarios,a provable data possession scheme with authentication was proposed.Based on data tag signature and randomness reusing,the proposed scheme

IDCrypt: A Multi-User Searchable Symmetric Encryption Scheme for Cloud Applications
IEEE Access, 2018 Searchable Encryption (SE) has been extensively examined by both academic and industry researchers. While many academic SE schemes show provable security, they usually expose some query information (e.g., search and access patterns) to achieve high ...

Provably Secure Covert Communication on Blockchain [PDF]
Cryptography, 2018 Blockchain is a public open ledger that provides data integrity in a distributed manner. It is the underlying technology of cryptocurrencies and an increasing number of related applications, such as smart contracts. The open nature of blockchain together with strong integrity guarantees on the stored data makes it a compelling platform for covert ...

Practical Fault-Tolerant Data Aggregation
, 2016 During Financial Cryptography 2012 Chan et al. presented a novel privacy-protection fault-tolerant data aggregation protocol. Comparing to previous work, their scheme guaranteed provable privacy of individuals and could work even if some number of users ...

A Synergistic Complexation‐Encapsulation Paradigm Enables Unprecedented Radioactive Remediation
Advanced Science, EarlyView.A novel HDEHP‐APG eutectic mixture‐based detergent is developed that achieves highly efficient decontamination of Am through a synergistic complexation‐encapsulation mechanism. Remarkably, such a detergent effectively removes radionuclides across a wide range of oxidation states (+I to +VII), demonstrating exceptional versatility.

Efficient and provable security amplifications [PDF]
, 1997 Even, Goldreich and Micali showed at Crypto''89 that the existence of signature schemes secure against known message attacks implies the existence of schemes secure against adaptively chosen message attacks. Unfortunately, this transformation leads to a rather impractical scheme. We exhibit a similar security amplification, which takes the given scheme
