Abstract

In this paper, we formally built the security models on key privacy in the multi-recipient and randomness re-using multi-recipient setting and proved their security. Two associated reproducibility tests concerning key privacy were proposed. Based on these results, we constructed a general shortened private broadcast encryption scheme which approximately halves ciphertext overhead and computational cost.
