Definitions
- Smart card of a terminal a terminal using a smart card
- the invention relates to a SIM card to be inserted in a terminal of a communications network.
- the invention further relates to a terminal of a communications network, which terminal is arranged so as to perform user identification when the terminal is activated.
- the invention relates to a method for identifying on the basis of a personal identification code an individual user of a terminal on a SIM card inserted in a terminal of a communications network.
- Various cellular systems apply different methods for identifying the user of a termi- nal.
- the lowest-level identification is a procedure in which it is verified that a user is entitled to use a cellular terminal.
- Such a verification is realized e.g. using a so-called PIN code (or Personal Identification Number).
- PIN code is a multiple-digit code which, when input to an apparatus correctly, allows the user to use the terminal in question.
- cellular phones of various systems require a PIN code of a few digits in order to grant access to the telephone functionality of a terminal. Only a call made to an emergency number can be made without giving the PIN code.
- SIM card Subscriber Identity Module
- a SIM card may further include other user-specific information which may allow the user to operate in the cellular network or contribute to it.
- Such information could include, among other things, various public or secret encryption keys used in the encryption of data transfers, and procedures used in user authentication.
- TETRA Transrestrial Trunked Radio
- ETSI European Telecommunications Standards Institute
- the TETRA network shall be easy to use and at the same time it shall have good data security with strong encryption properties.
- the authorities in different countries can be connected to one and the same TETRA network.
- the PIN codes and other possibly needed secret passwords used in identification must not be allowed to spread outside the user community.
- a problem with such shared use of terminals is, however, that the users must memorize several different identification codes because they often will not know which terminal they will be given to use in the next shift. Therefore, the identification information and the various passwords are attached using non-allowed methods to the terminal so that, when necessary, the terminal can be activated quickly.
- a PIN code known to the apparatus may be written on the back of the apparatus either on the casing of the apparatus or on a note glued onto the apparatus.
- a user may store the identification data of several terminals on a separate note. This way, the identification data associated with the use of a terminal may fall in the wrong hands, endangering the security and secrecy of the network used by the authorities. Because of the possibility of leaks of information, some systems recycle the PIN codes and other passwords more quickly than usual. This, however, may lead more likely than before to the users writing down the passwords on pieces of paper, which is naturally undesirable.
- An object of the present invention is to provide an apparatus, method and arrangement for ensuring both the security of operation and easiness of activation of a terminal in a multi-user environment.
- SIM card insertable in a cellular terminal, in connection of which SIM card it is stored user-specific identification information for each possible user.
- a SIM card according to the invention is characterized in that the SIM card comprises means for storing data used in the identification of at least two users and means for carrying out user identification using the said data.
- a terminal according to the invention is characterized in that the terminal's means for identifying a user comprise a SIM card arranged so as to identify at least two or more users entitled to use the terminal on the basis of at least one user-specific identification code.
- a method according to the invention is characterized in that user identification is carried out by matching the identification code given by the user against identification codes stored on the SIM card for different users, and if the identification code given by the user of the terminal is among the said identification codes, the activation of the terminal is allowed.
- SIM card is inserted in a cellular terminal, which SIM card stores several PIN codes for different users. Thus each user only needs to know his own PIN code independent of the terminal he is given. In addition to the PIN identification some other additional identification/password may be required of the user in order to grant him access to the functions of the terminal. In addition to separate PIN codes the SIM card may store various other user-specific data used in the encryption and communication. Such user-specific data can be used only by the identified user in question.
- An advantage of the invention is that only one SIM card has to be inserted in the shared cellular terminals so that each user may use the said SIM card with his personal PIN code/additional identifier.
- Another advantage of the invention is that the activation of a shared terminal becomes easier since it can be activated using the identification codes known to each user.
- SIM card may store other user-specific data for each user, which data may be utilized during a communications connection/session.
- Fig. 1 shows by way of example main parts of a SIM card according to the invention
- Fig. 2 shows by way of example a user-specific data structure on a SIM card
- Fig. 3 shows by way of example a flow diagram of a user identification procedure facilitating a SIM card according to the invention
- Fig. 4 shows by way of example a cellular terminal utilizing a SIM card according to the invention.
- Fig. 1 shows by way of example main parts according to the invention in a SIM card 10 insertable in a terminal of a cellular network.
- SIM card 10 On the SIM card according to the invention there is reserved user-specific data storage space for several users 1, 2,...N.
- Each user-specific record 11a, l ib, l ie is coupled through a connection 14 to an interface unit 12 in the SIM card.
- the SIM card Through the interface unit 12 the SIM card can be electrically coupled to the appropriate electrical connections in the terminal.
- the identification information/codes and code requests which grant a particular user access to the functions of the terminal, are input to the SIM card through the interface unit 12.
- the SIM card stores a record 15 advantageously shared by all users of the terminal.
- the quantity of user-specific records is limited only the by storage capacity of the SIM card.
- Fig. 2 shows by way of example the information advantageously included in a user- specific record 11a, l ib, l ie.
- Each of the records advantageously includes at least one user-specific PIN code 21.
- PIN codes are used to enable various functions for the users in question.
- PIN codes 22 are also advantageous to store at least one Personal Unblocking Code (PUK) 22 for each user. This code is used to prevent the breaking of the PIN code just by trying out different codes, for when a certain number of PIN codes have been tried the SIM card will require this longer code for the purpose of activating the terminal. If the PUK is entered incorrectly for a number of times, the SIM card will lock and the terminal will be rendered useless except for emergency calls.
- the SIM card advantageously stores other user-specific passwords 23 which the user possibly has to know when activating the cellular terminal.
- a SIM card according to the invention used in a cellular TETRA network may advantageously also include an Individual TETRA Subscriber Identification (ITSI) code 24. This information is needed in the communication in the TETRA network to identify the individual users.
- ITSI Individual TETRA Subscriber Identification
- a SIM card according to the invention advantageously includes an authentication key 25 needed for connecting the user with the cellular network.
- the SIM card advantageously includes various encryption keys 26 used in the encryption of traffic, which encryption keys are advantageously stored on the SIM card as user-specific data.
- a SIM card according to the invention advantageously stores also other user-specific data 27 useful to the operation of the network or the user.
- Fig. 3 shows in the form of an exemplary flow diagram how a SIM card according to the invention can be utilized in a terminal of a cellular TETRA network.
- a SIM card including user-specific records 11a, l ib, l ie of several users is connected to the terminal.
- the terminal is switched on.
- the user is requested for the PIN code and he must then respond by entering the PIN code known to him, step 32.
- step 33 the PIN code given by the user is matched against data stored on the SIM card 10.
- step 34 it is decided whether the PIN code given by the user of the terminal is accepted or not. If the PIN code is not accepted, the PIN code is advantageously requested again, returning to step 32. In this loopback from step 34 to step 32 it is possible to include a counter function for the PIN code attempts, not shown in Fig. 3, in which after a predetermined number of attempts a PUK code needs to be given for the procedure to continue.
- step 35 When the PIN code has been accepted the user may be requested for some additional identifier/password/identification code in step 35. If no additional identifier is required, the procedure moves on to step 39 in which the terminal is ready. If, how- ever, an additional identifier/user-specific password has to be accepted, the procedure moves from step 35 to step 36. In step 36 the user enters the additional identifier/password known to him. In step 37 the additional identifier/password given by the user is matched against the user-specific additional identifier/password 23 in the SIM card's memory. If the additional identifier/password given by the user is acceptable, the procedure moves from step 38 to step 39 in which the terminal is ready.
- step 38 If in step 38 it is found that the additional identifier/password entered does not match the data 27 stored in the memory of the SIM card, the procedure returns to step 36 in which the user is requested to give the correct additional identifier/password again.
- this loopback from step 38 to step 36 it is possible to include a counter function for the additional identifier/password attempts, not shown in Fig. 3, in which after a predetermined number of attempts a PUK code needs to be given for the procedure to continue.
- step 37 follows directly after step 34 if the PIN code matching 34 yields an acceptable result.
- the mutual order of the PIN code matching 34 and additional identifier matching 37 can be changed without any effect on the end result of the identification routine.
- Fig. 4 shows a simplified block diagram of a terminal 400 according to the inven- tion.
- the terminal comprises an antenna 401 for receiving and transmitting radio- frequency (RF) signals.
- a received RF signal is directed by a switch 402 to a RF receiver 411 where the signal is amplified and converted digital.
- the signal is then detected and demodulated in block 412.
- Block 413 performs decryption and deinterleaving.
- Signal processing in block 430 Received data may be stored as such in the memory 404 of the mobile station or, alternatively, the processed packet data are transferred after the signal processing to a possible external device such as a computer.
- the control unit 403 controls the above-mentioned reception blocks in accordance with a program stored in the unit.
- Transmission from the terminal is performed e.g. as follows. Controlled by the control block 403, block 433 performs possible signal processing on the data and block 421 performs interleaving and encryption on the processed signal to be transmitted. Bursts are generated from the encoded data, block 422, which are modulated and amplified into a RF signal to be transmitted, block 423. The RF signal to be transmitted is conducted to the antenna 401 through the switch 402. Also the processing and transmission functions described above are controlled by the control unit 403.
- the component essential from the point of view of the invention is the SIM card 405 inserted in the device.
- This SIM card stores all the user-specific data as well as the shared information needed in the operation of the terminal.
- the terminal according to the invention utilizes a display 432 and keyboard 431. All the codes required by the SIM card are input to the terminal advantageously through the said keyboard.
- the invention as such does not impose any requirements different from the prior art on the base stations, not shown in Fig. 4, in the cellular TETRA network.
- Embodiments according to the invention were described above.
- the invention is not limited to the embodiments just described.
- the order of requesting for the PIN codes and other identifiers may be other than the order according to the example used in the description.
