Attribute-based encryption (ABE) is a preferred technology used to access control the data
stored in the cloud servers. However, in many cases, the authorized decryption user may be …

We propose two new ciphertext policy attribute-based encryption (CP-ABE) schemes where
the access policy is defined by AND-gate with wildcard. In the first scheme, we present a …

In cloud computing, attribute based encryption (ABE) is often used to solve the challenging
issue in secure data storage. In order to lighten the burden of authority center, hierarchical …

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

Attribute-based encryption (ABE) has opened up a popular research topic in cryptography
over the past few years. It can be used in various circumstances, as it provides a flexible way …

In ciphertext-policy attribute-based encryption (CP-ABE) scheme, a user's secret key is
associated with a set of attributes, and the ciphertext is associated with an access policy …

With flexible and scalable features for fine-grained access control, ciphertext policy attribute-
based encryption (CP-ABE) is widely used as a kind of data protection mechanism in cloud …

In PKC 2010, Herranz et al. proposed the first fully threshold ciphertext policy attribute‐
based encryption (CP‐ABE) scheme with constant length ciphertext. However, their scheme …

Abstract Attribute Based Encryption (ABE) is a promising and increasingly versatile
paradigm. Given the many potential uses of ABE schemes, constructing efficient schemes …

Abstract Attribute Based Encryption (ABE) is a type of public encryption in decryptor can only
decrypt the ciphertext if its attributes of secret key matches the attributes of ciphertext but …
