Abstract: A secure transmission method and an apparatus are provided. The method includes: a first device encrypts a packet header of a to-be-sent packet including first data according to a transport layer security protocol to obtain an encrypted packet header. The first data is encrypted by an application layer security protocol. The first device sends a first encrypted packet to a second device. The first encrypted packet includes the encrypted packet header and the first data. According to this application, if the to-be-sent packet includes the first data encrypted by the application layer security protocol, when encrypting the to-be-sent packet according to the transport layer security protocol, the first device encrypts the packet header of the to-be-sent packet, but does not encrypt the first data. Accordingly, after receiving an encrypted packet, the second device does not need to decrypt the first data according to the transport layer security protocol.
