Changan Chain Ecological Toolbox
The rich and practical blockchain ecological tools not only make the deployment and development process more convenient for developers, but also expand the boundaries of blockchain applications in terms of capabilities. Changan Chain is building a powerful ecological toolbox to enhance its application capabilities in various scenarios, such as smart contract vulnerability detection, anti-quantum multi-party secure computing, chain migration, ciphertext retrieval, etc.
Changan chain cipher text search tool
Blockchain technology has incomparable advantages over other technologies in ensuring data cannot be tampered with and is traceable. However, since all data in the blockchain system is public, other nodes on the chain can access the information on the blockchain, which is unacceptable for some applications that require information confidentiality. In order to protect user data For privacy, data needs to be encrypted before being uploaded to the chain, but the encrypted data loses its plaintext characteristics, making it impossible for users to retrieve it efficiently. How to protect the privacy of data on the chain while supporting the search of dense data on the chain is a problem faced in blockchain applications.
Changan Chain ciphertext retrieval tool uses searchable encryption technology to ensure data security while supporting the search of encrypted data, taking into account the security and availability of data; without reducing the strength of ledger data privacy protection, it is oriented to multiple users and multiple keys The word search scenario supports retrieval operations on dense data on the chain, which improves the usability and adaptability of Changan Chain.
As the world's first open source technology achievement that supports bilingual ciphertext retrieval in Chinese and English, the Changan Chain ciphertext retrieval tool does not require setting up index storage space in advance, thus greatly reducing the complexity of the search; at the same time, it does not require a predefined dictionary, thus reducing the cost of searching. It reduces storage overhead; it has the advantages of small index size, fast retrieval speed, and high reliability of retrieval results, which can fully meet the user's on-chain ciphertext retrieval needs.
