Legacy encryption systems depend on sharing a key (public or private) among the peers
involved in exchanging an encrypted message. However, this approach poses privacy …

Processing encrypted signals requires special properties of the underlying encryption
scheme. A possible choice is the use of homomorphic encryption. In this paper, we propose …

Privacy and data protection constitute core values of individuals and of democratic societies.
There have been decades of debate on how those values-and legal obligations-can be …

Encryption is a well established technology for protecting sensitive data. However, once
encrypted, data can no longer be easily queried aside from exact matches. We present an …

By using fog computing, cloud computing can be extended to the edge of the network.
Generally, in the public cloud, fog computing comprises three components: terminal device …

A key element of any mobile code based distributed system are the security mechanisms
available to protect (a) the host against potentially hostile actions of a code fragment under …

Privacy homomorphisms (PHs) are encryption transformations mapping a set of operations
on cleartext to another set of operations on ciphertext. If addition is one of the ciphertext …

Encryption is a common method to assure privacy of stored data. In many practical
situations, decrypting data before applying logic compromises privacy. The challenge is to …

Data outsourcing is an emerging paradigm that allows users and companies to give their
(potentially sensitive) data to external servers that then become responsible for their storage …

The processing and encryption of multimedia content are generally considered sequential
and independent operations. In certain multimedia content processing scenarios, it is …
