| Abstract(in English) | Broadcast encryption allows any legitimate users to decrypt the encryption of some content. The complete subtree scheme and the subset difference scheme are well-known broadcast encryption schemes with user revocation. In this paper, we propose two revocation scheme with shorter message header by assigning additional group keys in the CS scheme. The first scheme is a combinatorial-based scheme, and the second scheme is based on some cryptographic primitives. We also perform a simulation to evaluate the first our proposed schemes and compare them with the CS scheme and the SD scheme. The result indicates that our proposed schemes have as good performance as the SD scheme in terms of the size of the message header in the broadcast. |
