WebJul 16, 2011 · Because that's all that's needed. 48 bits give you an address space of 256 terabyte. That's a lot. You're not going to see a system which needs more than that any time soon. So CPU manufacturers took a shortcut. They use an instruction set which allows a full 64-bit address space, but current CPUs just only use the lower 48 bits. Crypto1 is a stream cipher very similar in its structure to its successor, Hitag2. Crypto1 consists of a 48-bit linear feedback shift register for the state of the cipher,a two-layer 20-to-1 nonlinear function used to generate the keystream, anda 16-bit LFSR which is used during the authentication phase … See more Crypto1 is a proprietary encryption algorithm (stream cipher) and authentication protocol created by NXP Semiconductors for its MIFARE Classic RFID contactless smart cards launched in 1994.
