- program memory program memory
- work memory work memory
- serial communication unit serial communication unit
- the data stored by the SIM card can be divided into four categories:
- the first type is fixed storage data. This type of data is written by the SIM card center before the mobile device (Mobile Equipment; ME) is sold, including the International Mobile Subscriber Identification Number (IMSI) and the authentication key ( Ki).
- the second type is temporarily stored data about the network, such as: Location Area Identification (LAI), Temporary Mobile Subscriber Identity (hereinafter referred to as TMSI), Prohibited The public telephone network code to be accessed, etc.;
- the third type is the relevant service code, for example: Personal Identification Number (hereinafter referred to as: PIN), unlock code (PIN Unblocking Key; hereinafter referred to as: PUK), billing fee Rate, etc.
- the fourth category is the telephone directory, which is the telephone number that the mobile phone user can enter at any time.
- the SIM card itself is protected by a PIN.
- the PIN is a four- to eight-digit personal password. Only when the user enters the correct PIN can the SIM card be enabled, and the mobile terminal can access the SIM card, and only the PIN. After the authentication is passed, the user can make an online call. 3) User identity authentication
- User identity authentication is performed between the network and the SIM card.
- the network At the beginning of authentication, the network generates a 128-bit random number (Rand), which is transmitted to the mobile station via the radio control channel.
- the SIM card is based on the key Ki in the card.
- the algorithm A3 calculates an authentication response (Signed Response; hereinafter referred to as SRES) for the received Rand, and sends the result to the network.
- SRES Secure Response
- the network side finds the user's key Ki at the authentication center, calculates the SRES with the same Rand and algorithm A3, and compares it with the received SRES. If they match, the authentication passes.
- the most sensitive data in the SIM card are the security algorithms A3, A8, keys Ki, PIN, PUK and Kc.
- the A3 and A8 algorithms are written when the SIM card is produced and cannot be read.
- the PIN code can be set by the user on the mobile phone, the PUK code is held by the operator, and Kc is derived from Ki during the encryption process.
- the SIM card is organized around the processor and includes the following memory:
- ROM Read Only Memory
- program memory typical capacity is 16K bytes, development system with SIM card, algorithms A3 and A8 (may also A38) are proprietary;
