A CHOSEN-CIPHERTEXT SECURE IDENTITY-BASED BROADCAST ENCRYPTION SCHEME

摘要：

Consider that the receivers are a group identities in identity-based broadcast encryption (IBBE), we use a strong one-time signature scheme to construct our new IBBE scheme. We use this signature scheme to sign the ciphertexts and make one of the identities that broadcast to derive from verification key. Furthermore, we prove that our scheme achieves chosen-ciphertext security.
