Chapter 8, Problem 4E
Explanation of Solution
Advanced Encryption Standard:
It is a cipher technique, which is chosen by U.S. government that secures the data. This method used to protect the data against unauthorized access. It has following features:
- Compared to other cipher technique, it is secure to transact the files.
- Cost effective and memory efficient.
Overview of development and implementation of cryptosystem which is given in “FIPS 197” standard:
- According to “FIPS 197” standard, “Rijndael”
algorithm process the data blocks of 128 bits using various cipher key lengths such as 128bits, 192 bits, and 256 bits. These key lengths can be referred as “AES-128”, “AES-192”, and “AES-256”. - The AES algorithm is adopted by U...
