  • Abstract In a multi-receiver encryption system, a sender chooses a set of authorized receivers and sends them a massage securely and efficiently as the message is well encrypted and only one ciphertext corresponding to the message is generated no matter how many receivers the sender has chosen. It can be applied to video conferencing systems, pay-per-view channels, distance education, and so forth. Due to privacy consideration, an authorized receiver may not expect that his identity is revealed. In 2010, anonymous multi-receiver identity-based (ID-based) encryption was first discussed, and furthermore, many works on the topic have been presented so far. Unfortunately, we find that all of those schemes are not CCA-secure in either confidentiality or anonymity. In this manuscript, we propose the first anonymous multi-receiver ID-based encryption scheme with CCA security in both confidentiality and anonymity. It also is the first CCA-secure scheme against insider attacks, and moreover, only one pairing computation is required in decryption.
