Notes on Property - Preserving Encryption

نویسنده

  • Adam O’Neill
چکیده

The first type of specialized encryption scheme that can be used in secure outsourced storage we will look at is property-preserving encryption. This is encryption where some desired property of the plaintexts is intentionally leaked by the ciphertexts. The two main examples we will study are deterministic encryption, which preserves the equality property, and order preserving encryption, which preserves order comparison.

Property Preserving Symmetric Encryption Revisited

At EUROCRYPT 2012 Pandey and Rouselakis introduced the notion of property preserving symmetric encryption which enables checking for a property on plaintexts by running a public test on the corresponding ciphertexts. Their primary contributions are: (i) a separation between ‘find-then-guess’ and ‘left-or-right’ security notions; (ii) a concrete construction for left-or-right secure orthogonalit...

Secure and Practical Computation on Encrypted Data by Muhammad Naveed

Because of the importance of computing on data with privacy protections, the cryptographic community has developed both theoretical and practical solutions to compute on encrypted data. On the one hand, theoretical schemes, such as fully homomorphic encryption and functional encryption, are secure but extremely inefficient. On the other hand, practical schemes, such as property-preserving encry...

Property Preserving Symmetric Encryption

Processing on encrypted data is a subject of rich investigation. Several new and exotic encryption schemes, supporting a diverse set of features, have been developed for this purpose. We consider encryption schemes that are suitable for applications such as data clustering on encrypted data. In such applications, the processing algorithm needs to learn certain properties about the encrypted dat...

SESOS: A Verifiable Searchable Outsourcing Scheme for Ordered Structured Data in Cloud Computing

While cloud computing is growing at a remarkable speed, privacy issues are far from being solved. One way to diminish privacy concerns is to store data on the cloud in encrypted form. However, encryption often hinders useful computation cloud services. A theoretical approach is to employ the so-called fully homomorphic encryption, yet the overhead is so high that it is not considered a viable s...

Introduction to Homomorphic Encryption

Homomorphic encryption enables computations on encrypted data. This property makes such encryption schemes useful in a wide variety of privacy preserving applications. This paper provides a brief survey on the homomorphic encryption. We describe the homomorphic cryptosystems from partially homomorphic encryption to fully homomorphic encryption. We also give some security analysis and describe h...
