| Abstract |
With the instantaneous growth of cloud usage, IoT devices, smart cities, 4G communication, augmented reality, and virtual reality the requirement for digital storage has also risen to accelerate. By delivering data storage and continuing to manage data, cloud storage has now become a crucial part of the new eon. The usage of cloud computing has expanded dramatically. Shifting data and information to cloud servers has reduced a lot of anxiety related to storing it on physical storage devices. The frugality of data submitted has been a vital duty to safeguard the security of sensitive data. Generally, cloud servers are prone to cyberattacks that will lead to the exploitation of specific sensitive data of enterprises or institutions. Hence, there is a need to give some efficient strategies that not only preserve the information maintained on the server but also do not hamper the facility of using services. Searchable Encryption (SE) refers to a technique that enables users to run search operations over encrypted data. Encryption of data is a need to ensure the privacy of their data. Searchable Symmetric Encryption (SSE) allows us to secretly send our data to another user while keeping the possibility to choose to search through the encrypted data. In this paper, we discussed searchable encryption in-depth, such as the efficiency of contemporary SE schemes, privacy challenges, different single and multiple read/write schemes, and some probable future improvements and ideas provided. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd 2023. |
