WebProviding an efficient revocation mechanism for identity-based encryption (IBE) is very important since a user’s credential (or private key) can be expired or revealed. revocable IBE (RIBE) is an extension of IBE that provides an efficient revocation mechanism. Previous RIBE schemes essentially use the complete subtree (CS) scheme of Naor ... Web2.1.2 Public Key-Based Authentication. Among public key-based authentication schemes, attribute-based encryption (ABE) and identity-based encryption (IBE) are the most common techniques. ABE achieves flexible one-to-many encryption based on attributes. The decryption of a ciphertext is possible only if the set of attributes of the user key ...
