1. A conference data transmission method for a security enhancement module, comprising:
receiving unencrypted first conference data transmitted by a conference transmission device in a case where an identity verification of a participant is passed;
acquiring a conference key corresponding to the first conference data, and encrypting the first conference data through the conference key, to obtain encrypted second conference data; and
transmitting the encrypted second conference data to the conference transmission device, so that the conference transmission device provides the encrypted second conference data to a conference client through a cloud platform;
wherein the acquiring the conference key corresponding to the first conference data, and encrypting the first conference data through the conference key, to obtain encrypted second conference data, comprises:
generating the conference key corresponding to the first conference data, and encrypting the first conference data through the conference key;
encrypting the conference key through a security key provided by the cloud platform, to obtain a cipher key;
obtaining the second conference data according to the encrypted first conference data and the cipher key;
wherein prior to the encrypting the conference key with the security key provided by the cloud platform, the method further comprises:
receiving the security key returned by the cloud platform in response to a key negotiation request transmitted by the conference transmission device;
wherein the security key is generated according to a device service type and/or a device authentication type of the conference transmission device; and
wherein the receiving the security key returned by the cloud platform in response to the key negotiation request transmitted by the conference transmission device comprises:
receiving a first key obtained after the cloud platform encrypts the security key through a platform private key; and
decrypting the first key through a pre-acquired platform public key, to obtain the security key.
