Attribute-based encryption (ABE) is a popular type of public-key encryption that enforces
access control cryptographically, and has spurred the proposal of many use cases. To …

Measuring efficiency is difficult. In the last decades, several works have contributed in the
quest to successfully determine and compare the efficiency of pairing-based attribute-based …

In modern cloud computing, the need for flexible and scalable orchestration of services,
combined with robust security measures, is paramount. In this paper, we propose an …

The pair encodings framework is an important result in the simplified design of complex
attribute-based encryption schemes. In particular, it reduces the effort of proving security of a …

Ciphertext-policy attribute-based encryption is a versatile primitive that has been considered
extensively to securely manage data in practice. Especially completely unbounded schemes …

Abstract In 1993, Benaloh and De Mare introduced cryptographic accumulator, a primitive
that allows the representation of a set of values by a short object (the accumulator) and …

More edge users opt to use Internet of Things (IoT) devices to collect their data (eg, health
data, social data, e-governance data, etc.), which are stored in central cloud service …

Ciphertext-policy attribute-based encryption (CP-ABE) has attracted much interest from the
practical community to enforce access control in distributed settings such as the Internet of …

In this paper we introduce a recent and evolved two-factor authentication (2FA) access
govern system specially designed for webbased cloud computing services. Our innovative …

As a subfield of elliptic curve cryptography, pairing-based cryptography has gained
significant attention due to its practical and flexible functionality. In pairing-based …
