Abstract
An example security processing method includes receiving data packets at a packet data convergence protocol (PDCP) layer from an upper layer and parsing header information of each of the data packets to determine a length of each of the plurality of headers within the corresponding header information and whether a security header is present or absent in the corresponding data packets. The method further includes identifying corresponding header information of the data packets in which the security header is present based on the determination. The method further includes encrypting, based on the determined header lengths, only each of the plurality of headers of the identified corresponding header information in which the security header is present, and thereafter transmitting the one or more data packets to a lower layer after adding information regarding each of the encrypted headers along with their encryption length into a PDCP header.
