Format Preserving Encryption
Encrypting Personally Identifiable Information (PII) in large databases has historically been difficult, because encrypting information typically implies expanding data and changing its format. Previous attempts to encrypt PII data like credit card numbers and Social Security Numbers without changing their format have used questionable cryptographic constructions. We examine the security model ...
متن کاملFormat-Preserving Encryption
Format-preserving encryption (FPE) encrypts a plaintext of some specified format into a ciphertext of identical format—for example, encrypting a valid credit-card number into a valid creditcard number. The problem has been known for some time, but it has lacked a fully general and rigorous treatment. We provide one, starting off by formally defining FPE and security goals for it. We investigate...
متن کاملFormat Controlling Encryption Using Datatype Preserving Encryption
DatatypePreserving Encryption (DTP) enables encryption of values within a certain character set into ciphertext restricted to the same set, while still keeping data length. This is in contrast to conventional block cipher modes which produce binary data, i e each encrypted character may have an arbitrary value, possibly outside the original character set, often accompanied with a length expans...
متن کاملPrivacy-preserving Attribute Based Searchable Encryption
Attribute Based Encryption (ABE) is a promising public-key cryptographic primitive that can be used for cryptographically enforced access control in untrusted storage. Storing data on untrusted storage not only requires data security for data owners but also poses data protection from untrusted storage server. To address this important requirement, Anonymous Attribute Based Encryption (AABE) is...
متن کاملPrivacy-Preserving Personal Health Record System Using Attribute-Based Encryption
Personal health record (PHR) service is an emerging model for health information exchange. It allows patients to create, manage, control and share their health information with other users as well as healthcare providers. In reality, a PHR service is likely to be hosted by third-party cloud service providers in order to enhance its interoperability. However, there have been serious privacy conc...
