Abstract

In threshold identity-based encryption, a sender encrypts a message under identities of a pool of users and assigns a threshold t to the ciphertext, and sends the resulting ciphertext to these users. The cooperation of at least t users among them is required to decrypt the given ciphertext. We propose a construction method for threshold identity-based broadcast encryption from any existing identity-based encryption.
