Secure storage—Confidentiality and authentication

Secure disk storage is a rich and complex topic its study challenging in theory as well practice. In case of loss or theft mobile devices (such laptops smartphones), the threat data exposure important natural security objective to guarantee confidentiality data-at-rest stored such (e.g. on disks solid-state drives). Classical approaches encrypt may have severe impact performance if underlying architectural specificities are not considered. particular, it usually assumed that an encryption scheme suitable for application must be length preserving. This so-called “full encryption” method provides but does provide cryptographic integrity protection. It indeed rules out use authenticated where authentication tag concatenated ciphertext. Moreover, requires storing tags, latency added due extra read/write accesses computations. We present comprehensive full solutions compare their features from perspective. additionally models systematized analysis techniques usable these settings (which has, up now, received little attention research community). finally review current state-of-the-art incremental cryptography new insights secure contexts.
