title = "Selective all-or-nothing transform: Protecting outsourced data against key exposure",
abstract = "This paper presents the selective all-or-nothing transform (SAONT). It addresses the needs of users who would like to use inexpensive cloud storage services, but do not trust their providers. Encrypted data are transformed and separated into a small private fragment kept on the user{\textquoteright}s device and a large public fragment which can be securely uploaded to a public cloud since decryption of the public fragment is infeasible without the private fragment. Therefore, outsourced data are protected even in a situation of key exposure. SAONT reduces performance overhead by combining block-wise fragmentation of a ciphertext with an application of an all-or-nothing transform only on a subset of the ciphertext.",
