contracts are automatically loaded and then executed according to their predefined logic (as specified bycodeHash). In Fig.1, we show a simple contract namedEtherBankin Solidity. Solidity is the statically typed object-oriented high-level programming language dedicated...
We implement our model on the Ethereum platform, design the NS-SLA audit smart contract by solidity programming language and deploy it on the blockchain. Because Ethereum provides a blockchain platform that allows developers to use smart contracts to develop applications on it and it is easy fo...
Each address has both a zero-knowledge balance (ZK-balance) and a plaintext balance. A secure commitment is used for the ZK-balance and a private computation circuit for creating the transfer method. The transfer is performed in a two-step procedure to achieve unlinkability of sender/receiver ...
In ABAC, you can use struct (or a programming language-based class instance) instead of strings to represent model elements. At the same time, model elements can be formulated according to specific business access rules. Policy files can define detailed policies and the requests can include ...
“ecalls” to invoke a virtual machine in the TEE to execute smart contracts. The virtual machine can be a software program that executes program instructions encoded in a particular programming language or in a binary format such as a bitstream. In some examples, the virtual machine may ...
We implement Pub-SubMCS on the Ethereum blockchain using Solidity as the programming language. We use the brownie framework [44] to develop, test, and deploy smart contracts on Ganache. As the brownie framework is based on Python, we have written Python scripts to deploy the smart contracts...
Software programming is composed of graphics, with Ethernet and fieldbus communication interfaces, to simplify the complex vision measurement system into an easy-to-use intelligent vision measurement sensor suitable for industrial applications [21, 22]. 3. Embedded Sensors and Artificial Intelligence Block...
into new re-encrypted ciphertext under the authorization of the data owner. the process does not change the plaintext information. however, most abpre schemes have efficiency problems when applied to incentive scenarios, because these schemes need to calculate the key components of all internal ...
The place match records the number of results that have been matched, and the place mismatch records the addresses of model verifiers that do not agree with the plaintext results. The transitions consensus and No consensus indicate consensus reached and consensus failed, respectively. Figure 10. ...
