Q. Explain the Bit-Level Encryption?
Bit-Level Encryption
- Data is divided into blocks of bits then altered by encoding/decoding, permutation, substitution, exclusive OR, rotation, and so on
- Encoding/decoding - decoder changes an input of n bits into an output of 2n bits; encoder has 2n outputs and only n outputs
- Permutation - transposition at the bit level
- Straight permutation - number of bits in input and output are preserved
- Compressed permutation - number of bits is reduced
- Expanded permutation - number of bits is increased
- May be implemented in hardware circuitry to be performed very quickly (referred to as P-boxes)
