Non-interactive Multi-client Searchable Symmetric Encryption with Small Client Storage. (arXiv:2212.02859v1 [cs.CR])
cs.CR updates on arXiv.org arxiv.org
Considerable attention has been paid to dynamic searchable symmetric
encryption (DSSE) which allows users to search on dynamically updated encrypted
databases. To improve the performance of real-world applications, recent
non-interactive multi-client DSSE schemes are targeted at avoiding per-query
interaction between data owners and data users. However, existing
non-interactive multi-client DSSE schemes do not consider forward privacy or
backward privacy, making them exposed to leakage abuse attacks. Besides, most
existing DSSE schemes with forward and backward privacy rely on keeping a …
