Mobile Cloud Computing: Foundations and Service Models combines cloud computing,
mobile computing and wireless networking to bring new computational resources for mobile …

Abstract In ACM CCS 2008, Boldyreva et al. proposed an elegant way of achieving an
Identity-based Encryption (IBE) with efficient revocation, which we call revocable IBE (RIBE) …

Cloud computing provides a flexible and convenient way for data sharing, which brings
various benefits for both the society and individuals. But there exists a natural resistance for …

Revocable identity-based encryption (RIBE) is an extension of IBE that supports a key
revocation mechanism, which is an indispensable feature for practical cryptographic …

Attribute-based encryption (ABE) is an attractive extension of public key encryption, which
provides fine-grained and role-based access to encrypted data. In its key-policy flavor, the …

Cloud computing provides enterprises and individuals with unlimited computing resources
and expandable storage space. However, data leakage occurs frequently due to the lack of …

The rapid development of the Internet of Things (IoT) has led to the emergence of more and
more novel applications in recent years. One of them is the e-health system, which can …

In the public key cryptosystems, revocation functionality is required when a secret key is
corrupted by hacking or the period of a contract expires. In the public key infrastructure …

A revocable identity-based encryption (RIBE) scheme, proposed by Boldyreva et al.,
provides a revocation functionality for managing a number of users dynamically and …

Revoking corrupted users is a desirable functionality for cryptosystems. Since Boldyreva,
Goyal, and Kumar (ACM CCS 2008) proposed a notable result for scalable revocation …
