This paper surveys the practical benefits and drawbacks of several identity-based encryption
schemes based on bilinear pairings. After providing some background on identity-based …

We design an encryption scheme called Multi-dimensional Range Query over Encrypted
Data (MRQED), to address the privacy concerns related to the sharing of network audit logs …

We present an identity-based cryptosystem that features fully anonymous ciphertexts and
hierarchical key delegation. We give a proof of security in the standard model, based on the …

We present the first aggregate signature, the first multisignature, and the first verifiably
encrypted signature provably secure without random oracles. Our constructions derive from …

The only known construction of identity-based signatures that can be proven secure in the
standard model is based on the approach of attaching certificates to non-identity-based …

In many applications, it is desirable to work with signatures that are short, and yet where
many messages from different signers be verified very quickly. RSA signatures satisfy the …

With computer networks spreading into a variety of new environments, the need to
authenticate and secure communication grows. Many of these new environments have …

Key escrow is inherent in identity-based encryption (IBE). A curious key generation center
(KGC) can simply generate the user's private key to decrypt a ciphertext. However, can a …

Searchable encryption schemes provide an important mechanism to cryptographically
protect data while keeping it available to be searched and accessed. In a common approach …

In an identity-based encryption (IBE) scheme, there is a key extraction protocol where a user
submits an identity string to a master authority who then returns the corresponding secret …
