Proxy Re-encryption Systems for Identity-Based Encryption
A proxy re-encryption system allows the proxy to transform ciphertexts encrypted under Alice’s public key into the different ciphertexts that can be decrypted by Bob’s secret ...

Efficient Chosen-Ciphertext Secure Identity-Based Encryption with Wildcards
Abstract. We propose new instantiations of chosen-ciphertext secure identitybased encryption schemes with wildcards (WIBE). Our schemes outperform all existing alternatives in term...

Fuzzy Identity-Based Encryption
We introduce a new type of Identity-Based Encryption (IBE) scheme that we call Fuzzy Identity-Based Encryption. In Fuzzy IBE we view an identity as set of descriptive attributes. ...

Chosen-Ciphertext Security from Identity-Based Encryption
Abstract. We propose a simple and efficient construction of a CCAsecure public-key encryption scheme from any CPA-secure identity-based encryption (IBE) scheme. Our construction re...

Identity-Based Decryption
Identity-based decryption is an alternative to identity-based encryption, in which Alice encrypts a symmetric key for Bob under a trusted authority’s public key. Alice sends Bob...
