Computing CloudCrypt: Enhancing Keyword Search and Data Sharing Security in Cloud

master of computer application

The passage discusses the benefits of cloud infrastructure in terms of cost reduction for hardware and software resources in computing. It also highlights the importance of encrypting information before outsourcing it to the cloud to ensure security. However, encrypted data can be difficult to search for and distribute compared to plain data. To address these issues, the passage proposes a solution called "ciphertext-policy attribute-based approach with keyword search and data sharing" (CPAB-KSDS) for encrypted cloud data.The CPAB-KSDS approach allows for secure keyword searches and data sharing while maintaining data confidentiality. The passage mentions that the security model of this approach is discussed, and a specific technique is presented, which is demonstrated to be secure in the random oracle model. It is also noted that the technique is resistant to chosen ciphertext and chosen keyword attacks, enhancing the overall security of the solution.Lastly, the passage points out that the proposed CPAB-KSDS construction is efficient and feasible, and a performance and property comparison indicates its superiority over other methods.
