Fully threshold broadcast encryption

Abstract

Threshold broadcast encryption (TBE) is a class of threshold cryptographic schemes that allow a sender to compute ciphertexts to ad hoc user groups. The plaintext can only be recovered if t of the pertaining recipients collaborate by each producing a partial decryption share. Existing TBE schemes require that the partial decryptions are transferred through… (More)
