Embodiment Construction

[0124] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0125] Such as figure 1 As shown, the present invention provides a Boolean retrieval attribute-based encryption method that can verify search results, comprising the following steps:

[0126] S1: Initialize the key generation center, the trusted third party and the cloud server respectively, and complete the system initialization;

[0127] S2: Use the initialized key generation center to generate a user attribute private key;

[0128] S3: After issuing the attribute private key to the user, use the initialized trusted third party to generate relevant data for the ciphertext;

[0129] S4: Based on the ciphertext after generating the relevant data, use the initialized trusted third party to generate a search request;

[0130] S5: Use the initialized cloud server to perform a search operation through a search request, and return the ciphertext that match...

Abstract

The invention discloses a Boolean retrieval attribute-based encryption method that can verify the search results, adopts the attribute-based algorithm of the ciphertext strategy and the linear secret sharing LSSS structure, regards the keywords as participants, and the user formulates the search strategy, matches In the process, the LSSS secret value is restored by calculation to realize Boolean retrieval. The method of the invention has high calculation efficiency, takes into account flexible search sentences and efficiency, realizes efficient search result verification while realizing Boolean search, and has flexible algorithm expression and high security.

Description

technical field [0001] The invention belongs to the technical field of data security, and in particular relates to a Boolean retrieval attribute-based encryption method that can verify search results. Background technique [0002] As a new information storage technology, cloud storage, because of its large storage capacity and low price, more and more users store data in the cloud. While enjoying the convenient services brought by cloud storage, users also bear the risk of data security. Although traditional encryption technology can guarantee the confidentiality of data, it reduces the availability of data. Searchable encryption technology supports retrieval of encrypted data while ensuring data security, which greatly improves data availability. The early searchable encryption schemes only supported single-keyword or multiple-keyword equivalent searches, and the expression form of the search statement was single, resulting in poor user experience. Based on the above sit...
