Abstract
Encryption algorithms can be used to help secure wireless communications, but securing data also consumes resources. The goal of this research is to provide users or system developers of personal digital assistants and applications with the associated time and energy costs of using specific encryption algorithms. Four block ciphers (RC2, Blowfish, XTEA, and AES) were considered. The experiments included encryption and decryption tasks with different cipher and file size combinations. The resource impact of the block ciphers w ....etc

Block Ciphers - Analysis, Design and Applications




Abstract
In this thesis we study cryptanalysis, applications and design of secret key
block ciphers. In particular, the important class of Feistel ciphers is studied,
which has a number of rounds, where in each round one applies a cryptographically
weak function.

Applications
The main application of block ciphers is that of encryption. We study the
available modes of operat ....etc

Stream Ciphers
• Generate a pseudo-random key stream &
xor to the plaintext.
• Key: The seed of the PRNG
• Traditional PRNGs (e.g. those used for simulations) are not secure.
E.g., the linear congruential generator:
Xi = a Xi-1 + b mod m
for some fixed a, b, m.
It passes the randomness tests, but it is predictible.
Linear Feedback Shift Registers
Feedback shift register:
(“register”, “feedback”, “shift”)
LFSR: Feedback fnc. is linear over Z2 (i.e., an xor):
Very compact & effici ....etc
