The rapid development of Internet of Things (IoT) enables digital twin (DT) technology to
precisely represent a real product in a virtual space by generating a multitude of IoT data …

We study how to construct efficient tweakable block ciphers in the Random Permutation
model, where all parties have access to public random permutation oracles. We propose a …

Data deduplication is of vital importance for mobile cloud computing to cope with the
explosive growth of outsourced mobile data. In order to ensure the privacy of sensitive …

We present an approach to enforce access revocation on resources stored at external cloud
providers. The approach relies on a resource transformation that provides strong mutual …

Abstract The iterated Even-Mansour cipher is a construction of a block cipher from r public
permutations P_1, ..., P_r which abstracts in a generic way the structure of key-alternating …

While many similarities between Machine Learning and cryptanalysis tasks exists, so far no
major result in cryptanalysis has been reached with the aid of Machine Learning techniques …

We present XPX, a tweakable blockcipher based on a single permutation P. On input of a
tweak (t_ 11, t_ 12, t_ 21, t_ 22) ∈ T and a message m, it outputs ciphertext c= P (m …

We prove that the 5-round iterated Even-Mansour (IEM) construction with a non-idealized
key-schedule (such as the trivial key-schedule, where all round keys are equal) is …

A complex problem when outsourcing data to the cloud is access control management.
Encryption, by wrap** data with a self-enforcing protection layer, provides access control …

Due to the powerful computing capability of quantum computers, cryptographic researchers
have applied quantum algorithms to cryptanalysis and obtained many interesting results in …
