Abstract

The present invention provides a trunking group communication public security implementation method and device, wherein said method comprises: when a terminal within a group initiates a group call, receiving a random number from a network side; in accordance with said random number and with a root key obtained in advance from the network side, generating an intermediate parameter, and also a first key used for non-access stratum (NAS) decryption and integrity protection; generating a second key in accordance with said intermediate parameter; in accordance with the second key, engaging in the decryption and integrity protection of data coming from a trunking group control channel (TGCCH) and from a trunking group traffic channel (TGTCH). The above technical solution provided in the present invention solves the problem of the related art whereby a terminal is not supported on a downlink shared channel in regard to a point-to-multipoint type of trunking group traffic, thus achieving multi-user security. A security mechanism for trunking group UE terminal trunking group communication public channels is thus implemented.
