--- CPU --- Program memory (ROM) --- Working memory (RAM) --- Data memory (EPROM or E2PROM) --- Serial communication module These five modules must be integrated into an Integrated Circuit (IC), otherwise their safety would be threatened. This is because the chip connections may become illegal access and misappropriation of SIM cards important clues. In practice, there are two different forms of SIM cards with the same functions: (A) Full-size SIM card (commonly known as big card), this form of SIM cards with the IC cards of the ISO 7816 Standard [ISO7816], similar to IC card. The card has since been shrunk to the standard size of 25mm × 15mm. (B) Embedded SIM card (commonly known as small card), the size of only 25 mm × 15 mm, is a semi-permanent packed to the cards in the mobile station equipment. Two cards have installed waterproof, wear-resistant, anti-static contact with high accuracy and reliability characteristics. 2.2 Cryptographic algorithm and secret key in SIM card The most sensitive information of SIM card is the cryptographic algorithm A3, A8, secret Ki, PIN, PUK and Kc. A3, A8 algorithm were written into the SIM card in the producing process, and most people could not read A3, A8 algorithm. HN code could be settled by the phone owners. PUK code is held by the operator. Kc was derived in the process of encryption from Ki. 5 PIN and PUK: --- PIN –Personal Identification Number --- 2 PINs exist (PIN 1 and PIN2) --- Limited attempts on PIN access --- PUK –PIN Unblocking Code --- Resetting PUK, resets PIN and the attempt counter --- Too many attempts on PUK blocks use permanently
