PC1 cipher
The Amazon Kindle e-book reader DRM system uses the PC1 cipher, also called the Kindle cipher or Pukall cipher 1.[1]
History
The PC1 cipher was designed by Alexander Pukall in 1991.[2][3]
Successors
Caracachs Cipher formerly known as PC3 Cipher was relased in 2000.[4]
PC4 was released in 2015. It's a block cipher specifically designed for DMR radio communication systems. It uses 253 rounds and the key size can vary from 8 bits to 2112 bits. The block size is 49 bits, the exact size of an AMBE+ DMR voiceframe. [5]
