Attribute-based encryption (ABE) is suitable for mobile cloud storage to protect data
confidentiality and realize fine-grained data access control. It is essential for ABE schemes …

We investigate the best-possible (asymptotic) efficiency of functional encryption (FE) and
attribute-based encryption (ABE) by proving inherent space-time trade-offs and constructing …

Attribute-based encryption (ABE) cryptographically implements fine-grained access control
on data. As such, data can be stored by an entity that is not necessarily trusted to enforce …

An important theme in the research on attribute-based encryption (ABE) is minimizing the
sizes of secret keys and ciphertexts. In this work, we present two new ABE schemes with …

Security threats such as data forgery and leakage may occur when sharing data in cloud
environments. Therefore, it is important to encrypt your data and securely access it when …

Cloud-based Internet of Things (IoT) management services can be utilized to acquire data
from devices at any point on Earth. Accordingly, controlling access to data managed by …

The three-volume proceedings LNCS 12491, 12492, and 12493 constitutes the proceedings
of the 26th International Conference on the Theory and Application of Cryptology and …

With the popularity of smart grids, plentiful of smart devices have been put into use, such as
smart meters and power assets. Due to limited computation capabilities and storage spaces …

Cloud storage service makes it very convenient for people to access and share data. At the
same time, the confidentiality and privacy of user data is also facing great challenges …

Bilateral access control model, emerging as a novel paradigm in access control, has
garnered extensive deployment within the domain of fog computing. This model offers on …
