We propose a methodology to construct verifiable random functions from a class of identity
based key encapsulation mechanisms (IB-KEM) that we call VRF suitable. Informally, an IB …

In this paper we show a relation between the notions of verifiable random functions (VRFs)
and identity-based key encapsulation mechanisms (IB-KEMs). In particular, we propose a …

We describe a practical identity-based encryption scheme that is secure in the standard
model against chosen-ciphertext attacks. Our construction applies “direct chosen-ciphertext …

We introduce the concept of identity based key encapsulation to multiple parties (mID-KEM),
and define a security model for it. This concept is the identity based analogue of public key …

We describe a new and practical identity-based key encapsulation mechanism that is secure
in the standard model against chosenciphertext (CCA2) attacks. Since our construction is …

We describe a new encryption technique that is secure in the standard model against
chosen ciphertext attacks. We base our method on two very efficient Identity-Based …

We extend the concept of key encapsulation to the primitives of identity-based and
certificateless encryption. We show that the natural combination of ID-KEMs or CL-KEMs …

The key escrow problem is one of the main barriers to the widespread real-world use of
identity-based encryption (IBE). Specifically, a key generation center (KGC), which …

We introduce the concept of identity-based encryption (IBE) with master key-dependent
chosen-plaintext (mKDM-sID-CPA) security. These are IBE schemes that remain secure …

This paper presents a first example of secure identity based encryption scheme (IBE) without
redundancy in the sense of Phan and Pointcheval. This modification of the Boneh-Franklin …
