This paper surveys the symmetric primitives suitable for the unusually strong versatility
requirements of end-to-end encryption in the context of IoT. For example, on the objects …

Abstract Fully Homomorphic Encryption (FHE) is a powerful tool that brings privacy and
security to all sorts of applications by allowing us to perform additions and multiplications …

Image/video compression is a widely used operation in our everyday life. Such an operation
usually proceeds independantly on small rectangular portions, so-called macroblocks, and …

This chapter is concerned with encryption techniques in the cryptographic sense of the term,
that is, techniques designed to ensure the confidentiality of data in general, regardless of its …

Privacy-preserving processing is desirable for cloud computing to relieve users' concern of
loss of control of their uploaded data. This may be fulfilled with homomorphic encryption …

Data compression is a procedure undertaken to convert the depicted data from one form to
another form post compression, which contains the same information but with the reduced …

準同型暗号は暗号文同士の加算や乗算が可能であり, データを秘匿したままで分析し活用可能な
技術の一つである. 準同型暗号の応用例としては暗号化データベースが挙げられる …

A computer-implemented method of encrypting a data object of variable size utilizing an
inner encryption algorithm can take a variable size input and of outputting, as its output, an …

Le chiffrement homomorphe est un système de cryptographie permettant la manipulation de
données chiffrées. Cette propriété offre à un utilisateur la possibilité de déléguer des …

Ce chapitre présente l'état d'avancement des techniques de chiffrement homomorphes, qui
permettent d'effectuer des traitements sur des données chiffrées. Ces techniques sont très …
