The growth of cloud infrastructure has resulted in significant cost savings for computer infrastructure hardware and software solutions. To preserve the integrity of data, information is sometimes safeguarded before being transmitted to the cloud. Encrypted knowledge is more difficult to locate and exchange than unencrypted information. However, this is the responsibility of the cloud service provider, as clients rely on the cloud to run fast queries and deliver results while maintaining data security. To overcome these concerns, we suggest encrypting cloud data using a ciphertext-policy attribute-based technique that includes keyword search and information sharing (CPAB-KSDS). The proposed approach allows you to do both: search for keywords based on attributes and send information based on attributes, as opposed to alternative systems that only support one of the two possibilities. In addition, if we do not engage with the PKG in the sharing area, the keyword in our theme may change. This essay also addresses the CPAB-KSDS concept and the corresponding security model. Furthermore, we usually suggest a specific theme and demonstrate that it is secure against chosen ciphertext and chosen keyword attacks in the random oracle model. As its characteristics and performance are tested, it becomes clear that the proposed structure is both practical and economical.
