The invention provides a method for encrypting a multicast video stream and managing a secret key, which belongs to the technical field of communication information security, and is characterized in that one secret key is used for encryption, more than one secret key is used for decryption, and the security multicast requirements of forward confidentiality, backward confidentiality and collusion cracking resistance are met at the same time. The multicast management node only generates a private key for each user once, and the private keys of the users are different from one another; when the group members change every time, the message sender only needs to generate a new auxiliary key according to the private information of the new authorized user; and the user obtains a new decryption key by using the new auxiliary key and the private key of the user to decrypt the multicast information.
