From a5bd9684d3045a3c9bfd37ecd15001c45d43a21a Mon Sep 17 00:00:00 2001 From: Supreeth Herle Date: Thu, 26 Mar 2020 09:16:14 +0100 Subject: sysmoISIM-SJA2: Add support for programming IMS private user identity This EF contains the private user identity of the user. EF.IMPI consist of NAI TLV data object values see IETF RFC 2486. The NAI shall be encoded to an octet string according to UTF-8 encoding rules as specified in IETF RFC 3629 ./pySim-prog.py -p 0 -x 001 -y 01 -s 8988211900000000004 -i 001011234567895 -k 8baf473f2f8fd09487cccbd7097c6862 --op 11111111111111111111111111111111 -o 8E27B6AF0E692E750F32667A3B14605D -a 85524953 -n isim.test --msisdn 0598765432100 --epdgid epdg.epc.mnc001.mcc001.pub.3gppnetwork.org --pcscf pcscf.ims.testop.org --ims-hdomain ims.testop.org --impi 1234567895@ims.testop.org Change-Id: Ic1ccf99b5aa45297ef1e43a43373df603f756379 --- pySim-prog.py | 4 ++++ pySim/cards.py | 22 ++++++++++++++++++++++ 2 files changed, 26 insertions(+) diff --git a/pySim-prog.py b/pySim-prog.py index f278015..3abd0bd 100755 --- a/pySim-prog.py +++ b/pySim-prog.py @@ -159,6 +159,9 @@ def parse_options(): parser.add_option("--ims-hdomain", dest="ims_hdomain", help="Set IMS Home Network Domain Name in FQDN format", ) + parser.add_option("--impi", dest="impi", + help="Set IMS private user identity", + ) parser.add_option("--read-imsi", dest="read_imsi", action="store_true", help="Read the IMSI from the CARD", default=False ) @@ -468,6 +471,7 @@ def gen_parameters(opts): 'epdgSelection' : opts.epdgSelection, 'pcscf' : opts.pcscf, 'ims_hdomain': opts.ims_hdomain, + 'impi' : opts.impi } diff --git a/pySim/cards.py b/pySim/cards.py index 56597b0..62163a1 100644 --- a/pySim/cards.py +++ b/pySim/cards.py @@ -385,6 +385,18 @@ class IsimCard(Card): else: return (None, sw) + def update_impi(self, impi=None): + hex_str = "" + if impi: + hex_str = s2h(impi) + # Build TLV + tlv = TLV(['80']) + content = tlv.build({'80': hex_str}) + + bin_size_bytes = self._scc.binary_size(EF_ISIM_ADF_map['IMPI']) + data, sw = self._scc.update_binary(EF_ISIM_ADF_map['IMPI'], rpad(content, bin_size_bytes*2)) + return sw + def read_impu(self): rec_cnt = self._scc.record_count(EF_ISIM_ADF_map['IMPU']) impu_recs = "" @@ -1301,6 +1313,16 @@ class SysmoISIMSJA2(UsimCard, IsimCard): if sw != '9000': print("Programming Home Network Domain Name failed with code %s"%sw) + # update EF.IMPI in ADF.ISIM + # TODO: Validate IMPI input + if self.file_exists(EF_ISIM_ADF_map['IMPI']): + if p.get('impi'): + sw = self.update_impi(p['impi']) + else: + sw = self.update_impi() + if sw != '9000': + print("Programming IMPI failed with code %s"%sw) + if '9000' == self.select_adf_by_aid(): # update EF-USIM_AUTH_KEY in ADF.USIM if p.get('ki'): -- cgit v1.2.3
