Security Measures for Dynamic Encrypted Search Data |
Abstract |
In the field of cloud security, Verifiable Searchable Symmetric Encryption (VSSE) is crucial, allowing
users to retrieve encrypted cloud data through keywords while preserving the integrity of the results.
However, current VSSE methods struggle with dynamic updates to cloud data because verifying these
updates using asymmetric-key cryptography is time-consuming, especially with large data volumes. To
address this issue, we propose a novel approach for efficient keyword searches on dynamically
encrypted cloud data using symmetric-key-based verification. Our method introduces Accumulative
Authentication Tags (AATs), which utilize symmetric-key cryptography to create authentication tags
for each keyword. AATs are designed to accumulate updates, facilitating easy authentication tag
adjustments during dynamic data changes. Additionally, we propose a secure indexing system that
includes a search table (ST) with orthogonal lists and a verification list (VL) with AATs. Through
extensive security analysis and performance testing, we show that our approach is both effective and
efficient. This solution not only meets the challenge of managing dynamic updates for encrypted cloud
data but also provides strong security, representing a significant advancement in cloud security
technology. |
