New Anonymity Notions for Identity-Based Encryption (Formal to Practical Security)
Adaptive-ID Secure Revocable Identity-Based Encryption (CT-RSA '09)
Towards Black-Box Accountable Authority IBE with Short Ciphertexts and Private Keys (PKC '09)
Verifiable Random Functions from Identity based Key Encapsulation (EUROCRYPT '09)
Identity-based encryption makes public-key cryptography much easier since the public key is simply the identity of the recipient: no certification of the public key is needed anymore. We studied several tools related to this primitive.
