In this paper we introduce the notion of a Public-Key Encryption Scheme that is also a Locally-Decodable Error-Correcting Code (PKLDC). In particular, we allow any polynomialtime ...
In a broadcast encryption scheme, digital content is encrypted to ensure that only privileged users can recover the content from the encrypted broadcast. Key material is usually he...
We present a secure network service for sovereign information sharing whose only trusted component is an off-theshelf secure coprocessor. The participating data providers send enc...

Exposure of secret keys seems to be inevitable, and may in practice represent the most likely point of failure in a cryptographic system. Recently, the notion of intrusion-resilien...

In a fuzzy identity-based encryption (IBE) scheme, a user with the secret key for an identity ID is able to decrypt a ciphertext encrypted with another identity ID if and only if I...
