Ua lomia e le au suʻesuʻe mai le Korea Advanced Institute of Technology le LTESniffer toolkit, lea e mafai ai ona e faʻagasolo (e aunoa ma le lafoina o faailo i luga o le ea) faʻatulagaina le faʻalogo ma le faʻalavelaveina o feoaiga i le va o se nofoaga autu ma se telefoni feaveaʻi i fesoʻotaʻiga 4G LTE. O le pusa meafaigaluega e tuʻuina atu ai mea faʻaoga mo le faʻatulagaina o faʻalavelave faʻalavelave ma se API faʻatinoga mo le faʻaogaina o galuega a le LTESniffer i talosaga a isi vaega.
LTESniffer e tu'uina atu le decoding o le auala faaletino PDCCH (Physical Downlink Control Channel) e maua ai fa'amatalaga e uiga i feoaiga mai le nofoaga autu (DCI, Downlink Control Information) ma fa'amatalaga feso'ota'iga le tumau (RNTI, Radio Network Temporary Identifier). O le fa'amalamalamaga o le DCI ma le RNTI e fa'atagaina atili ai le fa'avasegaina o fa'amaumauga mai le PDSCH (Physical Downlink Shared Channel) ma le PUSCH (Physical Uplink Shared Channel) e maua ai le avanoa i felauaiga ulufale ma fafo. I le taimi lava lea e tasi, LTESniffer e le fa'ailogaina fe'au fa'ailoga e tu'uina atu i le va o se telefoni fe'avea'i ma se nofoaga autu, ae na'o fa'amatalaga e tu'uina atu i tusitusiga manino. Mo se faʻataʻitaʻiga, o feʻau na lafoina e le nofoaga autu i le faʻasalalauga faʻasalalauga ma feʻau fesoʻotaʻiga muamua e tuʻuina atu e aunoa ma se faʻailoga, lea e mafai ai ona aoina faʻamatalaga e uiga i le numera, o anafea ma o le fea numera na i ai telefoni).
Fa'alavelave e mana'omia ni meafaigaluega fa'aopoopo. Ina ia faʻalavelaveina feʻaveaʻi mai le nofoaga autu, o le USRP B210 programmable transceiver (SDR) ma lua antenna, tau e tusa ma le $ 2000, ua lava. Ina ia faʻalavelaveina feʻaveaʻi mai se telefoni feʻaveaʻi i se nofoaga autu, o se USRP X310 SDR laupapa e sili atu le taugata faʻatasi ai ma isi transceivers e lua (o le tau o le pusa e tusa ma le $ 11000) e manaʻomia, talu ai o le sogisogi faʻafuaseʻi o pepa na lafoina e telefoni e manaʻomia ai le taimi saʻo i le va o faʻavaa lafo ma mauaina. ma fa'ailo fa'afeiloa'i fa'atasi i alavai eseese e lua. E manaʻomia foʻi se komipiuta e lava le malosi e faʻavasega ai le protocol, mo se faʻataʻitaʻiga, e faʻavasegaina le fefaʻatauaʻiga o se nofoaga autu ma 150 tagata faʻaoga malosi, o le Intel i7 CPU system ma le 16GB o le RAM e fautuaina.
Autu autu ole LTESniffer:
- Fa'ailoga taimi moni o alavai fa'atonutonu LTE i fafo ma le ulufale mai (PDCCH, PDSCH, PUSCH).
- Lagolago mo LTE Advanced (4G) ma LTE Advanced Pro (5G, 256-QAM) faʻamatalaga.
- Lagolago mo DCI (Downlink Control Information) formats: 0, 1A, 1, 1B, 1C, 2, 2A, 2B.
- Lagolago mo auala fesiitaiga: 1, 2, 3, 4.
- Lagolago mo alaleo vaevaega fa'atele (FDD).
- Lagolago mo nofoaga fa'avae e fa'aoga alaleo e oo atu i le 20 MHz.
- Otometi su'esu'ega o polokalame fa'aogaina fa'aogaina mo fa'amatalaga ulufale ma fafo (16QAM, 64QAM, 256QAM).
- Otometi su'esu'ega o tulaga fa'aletino mo telefoni ta'itasi.
- LTE Security API lagolago: RNTI-TMSI faʻafanua, aoina IMSI, faʻamatalaga.
