%X SRTP provided confidentiality, message authentication, and replay protection to the RTP traffic. One of the hard point to implement SRTP was to calculate the packet index and update the ROC and s_l. The packet index maintenance algorithm suggested in the RFC3711 was analyzed, based on which introduced an optimized algorithm to improve the SRTP performance under hardware pipeline and/or multiprocessor architecture implementation, and a comparison on the two algorithms was done based on the HIPP security chip's SRTP implementation.
