Plenty　of　applications　and　services　for　personal　communications　in　wireless　mobile　networks　(WMN)　are　brought　up　recently,　such　as　mobile　commerce　applications　and　teleconference　applications.　So　the　end-to-end　security　requirements　are　necessary.　Nevertheless　WMN　don＇t　offer　end-to-end　confidentiality　and　integrity　mechanism　for　personal　communications.　The　linchpin　of　end-to-end　security　is　the　authentication　of　users.　Considering　the　limited　wireless　bands　and　the　limited　computing　ability　of　mobile　devices,　we　present　a　simple　authentication　and　key　distribution　protocol　(SAKDP)　for　end-to-end　secure　communications.　Based　on　symmetric　cryptography　and　one-way　function　techniques,　SAKDP　is　satisfied　with　secure　requirements　of　wireless　end-to-end　secure　communication,　also　enables　dynamic　secure　communications.　The　proposed　scheme　also　has　identity　anonymity　and　encryption　key　renewal　mechanism,　its　computation　cost　and　transmission　cost　are　smaller.
