Practical Identity-Based Encryption (IBE) in Multiple PKG Environments and Its Applications
Abstract. Identity-based encryption (IBE) schemes are usually used in multiplePKG environments — on the one hand, each administrative domain (e.g., a relatively small and close o...

Identity-based encryption with efficient revocation
Identity-based encryption (IBE) is an exciting alternative to public-key encryption, as IBE eliminates the need for a Public Key Infrastructure (PKI). Any setting, PKI- or identit...

Direct chosen ciphertext security from identity-based techniques
We describe a new encryption technique that is secure in the standard model against adaptive chosen ciphertext (CCA2) attacks. We base our method on two very efficient Identity-Ba...

Building Key-Private Public-Key Encryption Schemes
In the setting of identity-based encryption with multiple trusted authorities, TA anonymity formally models the inability of an adversary to distinguish two ciphertexts correspondi...
