The disclosure provides a method and an apparatus for processing Device-to-Device (D2D) device identity. The method includes that: a D2D device transmits a temporary D2D identity request; the D2D device receives temporary D2D identity authorization information corresponding to the temporary D2D identity request, and acquires a temporary D2D identity; and the D2D device broadcasts the received temporary D2D identity, wherein the temporary D2D identity is configured to discover the D2D device by a discovering D2D device in a D2D discovery process. By the disclosure, the security of communication among the D2D devices is improved.
