Symmetric Searchable Encryption (SSE) schemes solve efficiently the problem of securely outsourcing client data with search functionality.  ...  Our attacks are passive and only assume the knowledge of a small sample of plaintexts.  ...  SYMMETRIC SEARCHABLE ENCRYPTION We introduce notations, then we formalize SSE schemes and discuss the associated security notion.  ...

For instance, common protection against malicious insiders, i.e., non-disclosure agreements, is purely organizational. Clearly, such measures cannot prevent misuses but can at least discourage it.  ...  We have focused particularly on insider attacks because the prevention against them automatically covers other attacks.  ...  Alternatively, through searchable encryption [22] , one is able to perform logarithmic searches while maintaining strong privacy guarantees simultaneously.  ...

The experiment demonstrates that without relying on the performance of the blockchain, the LMCPTEE is practical, feasible, low-performance overhead.  ...  database, but symmetric key encryption has the risk of key leakage.  ...  To handle the attacks, LMCPTEE uses AES to encrypt and decrypt files in the SGX platform because the AES instructions can protect AES against side channels attacks.  ...

The PASStree provides strong privacy guarantees against attacks from a semi-honest adversary.  ...  While encryption of data provides sufficient protection, it is challenging to support rich querying functionality, such as string matching, over the encrypted data.  ...  We assume that the index and the trapdoor construction relies on symmetric key encryption algorithms, i.e., our solution is a symmetric searchable encryption (SSE) [5] , [6] scheme.  ...

While TLS helps defend against pervasive surveillance of intercepted unencrypted traffic, it also hinders several common beneficial operations typically performed by middleboxes on the network traffic.  ...  Searchable encryption-based solutions Techniques based on searchable encryption have been proposed to preserve the privacy of filtered traffic.  ...  This behavior is often (abusively) referred to as a man-in-the-middle attack.  ...
