Introduction to IDEA Algorithm implementation with VHDL
Jul 21, 2021
Encryption can be of two types — Symmetric key or asymmetric key
IDEA (International Data Encryption Algorithm)
- Symmetric
- Block cipher, 4 x 16 bit input / output data
- 128 bit key (52 partial keys of 16 bit length)
- 16 bit operations — XOR, addition modulo 2 power 16, multiplication modulo 2 power 16 + 1.
