Access to secret data should be managed to allow authorized people only. An authenticated encryption scheme can be used to protect valuable information or secret data for data confidentiality, authentication, non-repudiation and integrity. In this pa-per, the authors propose a new supervising authenticated encryption scheme for multilevel security which deals with the monitor and access control problems found in hierarchical organization, for protecting valuable authenticated encryption messages from being disclosed by malicious adversary. The proposed scheme provides two effective access control mechanisms, one is the partial access control and the other is the complete access control, which allows management superiors to monitor or access authenticated encryption messages received by inferiors within a hierarchical organization.
