    Abstract: A method for detecting encrypted content and a device, where the method includes receiving, by a middlebox network device using a first secure channel, key information of a Transport Layer Security (TLS) secure channel from a key manager, obtaining, by the middlebox network device based on 5-tuple information of the TLS secure channel, encrypted application data transmitted over the TLS secure channel, decrypting, by the middlebox network device, the encrypted application data using a session key, and detecting decrypted content. Hence, the middlebox network device decrypts the encrypted application data, and detects decrypted application data. In this way, detection of encrypted content does not rely on a TLS proxy server, and detection complexity and detection costs can be reduced.

    Abstract: A packet processing method and an apparatus are provided. A first SFC proxy of a first SF entity splits a first packet to obtain a first original packet and a first SFC header, and the first SFC proxy sends the first SFC header to a second SFF. The first SF entity processes the first original packet to obtain a second original packet, and sends the second original packet to a service classifier. The service classifier sends, to the second SFF, a second packet that is obtained after the service classifier adds a second SFC header to the second original packet. The second SFF changes the second SFC header in the second packet into the first SFC header. In this way, a first packet carrying a first SFC header can be transmitted in a network architecture in which a legacy SF exists, so that the legacy SF becomes compatible.

    Abstract: The present invention discloses a service processing method and apparatus, and relates to the communications field. The method includes: receiving trigger information sent by an intermediary device; and assisting, based on the trigger information, the intermediary device in negotiating with UE and a network server, to enable the intermediary device to obtain a first key, where the first key is used by the intermediary device to decrypt ciphertexts sent by the UE and the network server, the ciphertext is obtained after the UE or the network server encrypts service information by using a second key, and the first key is corresponding to the second key. The present invention resolves a problem that an intermediary device cannot provide service optimization for user equipment and a network server because the intermediary device cannot decrypt ciphertext, and achieves an effect of expanding a usage scope of service optimization.
