Identity-Based Encryption (IBE) which simplifies the public key and certificate management
at Public Key Infrastructure (PKI) is an important alternative to public key encryption …

Identity-based encryption (IBE) is an exciting alternative to public-key encryption, as IBE
eliminates the need for a Public Key Infrastructure (PKI). The senders using an IBE do not …

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 has emerged as a pivotal trend across both commercial and academic
sectors, offering substantial storage capabilities to service providers and end-users …

As a one-to-many public key encryption system, attribute-based encryption (ABE) enables
scalable access control over encrypted data in cloud storage services. However, efficient …

Generalized signcryption (GSC) can be applied as an encryption scheme, a signature
scheme, or a signcryption scheme with only one algorithm and one key pair. A key‐insulated …

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 …

Boneh and Franklin gave a naive revocation method in identity-based encryption (IBE)
which imposes a huge overhead into the key generation center. Later, Boldyreva, Goyal …

We firstly combine the concepts of key-insulated encryption (KIE) and identity-based
encryption with the equality test (IBE-ET) to obtain identity-based keyinsulated encryption …

Standard identity-based (ID-based) signature schemes typically rely on the assumption that
secret keys are kept perfectly secure. However, with more and more cryptographic primitives …
