1 NSK 200 GSM Secure Telephone, NSK 201 DECT Single Base Station and NSK 250 Secure Management Centre (NDLO/CIS)

2 2 Why encrypted GSM phone? Encrypted radio connectionNone encryption in public networks Public networks

3 3 Features of the NSK 200 Encrypted radio linkNon-encrypted radio link Non-encrypted traffic in the public network Public network Secure communication up to NATO SECRET level

4 4 Features of the NSK 200 Conversations up to NATO SECRET GSM-GSMGSM-DECT DECT-DECT

5 5 GSM Transmission channels Encrypted data channel Voice transmission Data transmission Is used towards NSK 200 Plaintext speech channel As ordinary GSM/DECT Used between all other phones SMS can only be sent as plaintext

6 6 GSM/DECT Data transmission Encrypted File-transfer NATO SECRET IrDA GSM/PSTN 9,6 kb/s DECT/PSTN 28,8 kb/s

7 7 NSK Technical details Dimensions:56 x 140 x 30 mm Weight:235 g GSM phase 2:Dual band 900/1800 MHz Battery capacity: mAh Stand-by-time:Approx. 70 hours Operation time:Approx. 3 hours Data Interface:Infrared, IrDA Data Speed:GSM: 9,6 kbit/s DECT: up to 28,8 kbit/s Security:NATO UNCLASSIFIED NATO RESTRICED NATO CONFIDENTIAL NATO SECRET

8 8 NSK 200 Overview Smart Card Interface Battery Charger Hands-free Contact IrDA Interface Menu-wheel Quick-menu

9 9 Accessories NSK 200 bracket for car Car charger Hands-free combined w/external antenna DECT Base station w/connection to PSTN, analogue line Tabletop charger Portable charger 220V

10 10 Features of the NSK 200 Encrypted speech is transmitted using the GSM asynchronous transparent data service The GSM net performs interleaving of data packets, which results in a minor delay when using encrypted speech Encrypted speech and data Plaintext speech and data Plaintext SMS Encrypted SMS is not supported

11 11 Digital Enhanced Cordless Telecommunications (DECT) SUB PowerPSTN (Analogue line) Registration button Green LED (power) Red LED (call/registration)

12 12 Digital Enhanced Cordless Telecommunications (DECT) SUB Public network

13 13 Features of the DECT SUB The DECT SUB, NSK 201, is mainly used in areas without GSM coverage, connected to the PSTN by an analogue line The NSK 200 must be registered in the DECT SUB before making calls This is done by activating registration menu in the NSK 200 and pressing the Registration button on the SUB

14 14 Encrypted speech and data Plaintext speech and data NSK 200 supports 28,8 kbps for data calls in DECT mode. Features of the DECT SUB

15 15 Security Management Centre (SMC) SMC OSP SMC (Other Service Provider)

16 16 Features of the SMC The main purpose of the SMC is to distribute traffic keys to the SPs (Secure Phones) in the system. The SMC is configured as a dual SMC. The SMC includes a database comprising all customer information. SMC can be connected in a network to other OSP (Other Service Provider) SMCs.

17 17 Key Management Traffic Key Can be fetched from everywhere Group Key Has to be loaded by Crypto Custodian Only valid for a minor group NSK 200 can be loaded with both Traffic Key and Group Keys Traffic Key Can be fetched from everywhere

18 18 Security Requirements 1.General information of the NSK 200 and security classification. 2.Physical Security of NSK Be aware threat of acoustic eavesdropping 4.Use of infrared transmission 5.How the Access Card is functioning 6.How to clear key memory in NSK Emergency destruction of the NSK Breach of Security. Two SDIPs (User and System) under publication The user of NSK 200 shall be familiar with National Security Requirements:

19 19 How to use NSK Switch on the phone Insert CIK Ok Skip Please wait, communicating with SC… 2.Insert CIK and press ”OK” You can now remove CIK Ok 3.Remove CIK (insert the PIN code) Enter PIN1 Ok Skip **** 4.Ready for use in encrypt. mode Encr. mode :44 N Telenor Last No. Ph.book

20 20 How to make encrypted call ? NSK 200 in Encrypted Mode: Three ways to make a call: 1.Dial the number directly 2.Quick code buttons 3.Via Phone Book Via Phone Book, select person: Select number, press ”Call”: A voice is announcing security level of the call twice, than the connection is established: Encr. mode :44 N TELENOR Last No Ph.book Encrypted speech Client Name Connecting End NATO RESTRICTED 1:47 Client Name Choice End

21 21 How to make plaintext call ? NSK 200 in Plaintext Mode: Select ”Make plain call” in the menu The connection is established: Dial number and press ”Call” Encrypion mode :44 N TELENOR Latest Ph.book Make plain call Ok Cancel Plaintext mode Call Delete Three ways to make a call: 1.Dial the number directly 2.Quick code buttons 3.Via Phone Book Plain speech Connecting Choice End

22 22 How to make encrypted DECT call ? NSK 200 in Encrypted Mode: Three ways to make a call: 1.Dial the number directly 2.Quick code buttons 3.Via Phone Book Via Phone Book, select person: Select number, press ”Call”: A voice is announcing security level of the call twice, than the connection is established: Encr. mode :44 N TELENOR Last No Ph.book Encrypted speech Client Name Connecting DECT End NATO RESTRICTED 1:47 Client Name Choice End Select DECT on the Quick Menu ”R”-buttton Encr. mode :44 DECT Name Last No Ph.book
