The invention discloses a multi-modal sensor abstract description and packaging method and system based on software definition. Firstly, a unified sensor abstract description model based on software definition is introduced, so that hardware independence is realized, and the differences of a bottom-layer multi-mode sensor in the aspects of interfaces, protocols and data formats can be effectively shielded; secondly, abstract packaging of data is achieved through an autonomous information processing module, and high-bandwidth and high-redundancy original data is converted into low-bandwidth and high-value structured information; in addition, by means of automatic registration, discovery, scheduling and control mechanisms of the sensor management control module on sensor resources, the system realizes a real plug-and-play function. According to the invention, by deploying the autonomous information processing modules at various sensor nodes, the original sensing data is preprocessed, and standardized data packaging with semantic consistency is output, so that the operation load of the central controller is reduced, and the information processing efficiency and the system response capability are also improved.

The invention relates to the technical field of internet analysis, in particular to an internet vulnerability evaluation and analysis system, which comprises the following steps of: acquiring original vulnerability data, binding an evaluation terminal equipment fingerprint, an operator biological characteristic hash, a network environment snapshot and generating a vulnerability responsibility label; stripping an environment dependency item in the vulnerability responsibility label, replacing the environment dependency item with a cross-platform equivalent function, and generating a repair instruction chain; executing the restoration instruction chain in a target environment, and capturing restoration behavior offset; and associating the system repair behavior offset with the vulnerability responsibility label, reversely positioning a responsibility node and generating a traceability tree. The method not only breaks through the information splitting problem that the repair behavior of the traditional system cannot reversely deduce the responsibility attribution, but also supports the positioning of the responsibility node through the traceability tree, and provides a matched evidence data packet.

The application provides a kind of automobile ECU cross-domain interaction verification method, system, electronic equipment and storage medium, in the method, by introducing automobile ECU cross-domain interaction verification system between business layer and bottom bus tool, unified general operation instruction is converted into the private interface call instruction of each tool using mapping relationship, so as to shield the difference of bottom hardware interface, the decoupling of test logic and hardware tool is realized, the complexity and maintenance cost of cross-tool, cross-platform test are significantly reduced.Not only greatly reduces the complexity and maintenance cost of software and hardware engineering construction, but also makes it only need to update mapping configuration when switching vehicle type or upgrading tool without modifying business code, significantly improves the flexibility and scalability of test system.

The application discloses a blockchain cross-chain transaction credible verification method, an adapter of an access cross-chain gateway is configured for each blockchain, the blockchain sends self verification rules and corresponding verification functions to the adapter and the cross-chain gateway through registration, the adapter saves the verification functions, the cross-chain gateway converts executable files of the verification rules into verification services, each blockchain, the adapter and the cross-chain gateway obtain identity credentials through a cross-chain alliance; the blockchain initiates a cross-chain transaction request to the corresponding adapter, an origin blockchain adapter generates a cross-chain Merkle tree and packs the cross-chain Merkle tree into cross-chain transaction data to forward to a target blockchain through the cross-chain gateway and an adapter of the target blockchain, in the process, each component verifies identity through the identity credentials, and verifies data through the cross-chain Merkle tree, until the transaction is completed. The application realizes the reliability of a complete life cycle of cross-chain transaction based on a cross-chain Merkle tree, in combination with verification rules and a verification link.
