A data transmission method and apparatus are disclosed that resolves a technical problem where an existing data encryption algorithm offers poor security during transmission of data. The solution includes obtaining, by a first terminal, a data transmission request sent by a second terminal, the data transmission request at least carrying first encrypted data that is obtained by encrypting first exchange key of the second terminal by using a private key of the second terminal. The solution further includes decrypting, by the first terminal, the first encrypted data by using a public key of the second terminal to obtain the first exchange key, and obtaining a shared key of the first terminal and the second terminal according to the first exchange key. The solution further includes encrypting, by the first terminal, to-be-transmitted data by using the shared key to obtain encrypted to-be-transmitted data, and sending the encrypted to-be-transmitted data to the second terminal.

Data transmission method and apparatus

The present invention provides a method for processing channel access and an apparatus thereof. The method includes: receiving a fallback to physical random access channel (PRACH) indication sent by a base station; and initiating access on a common enhanced dedicated channel (E-DCH). In the present invention, a fallback to PRACH indication is not executed, so as to prevent a user terminal from being in a DRX off state when a base station sends downlink data to the UE, thereby preventing the base station from delaying sending the downlink data to the UE.
