Agenda

1. Introduction

2. The System and the Solution

3. Encryption Scheme and Optimization

4. Simulation and Experiments

5. Summary and Future Work

1. Introduction

Most swarm intelligence algorithms are inspired by simple self-

designed synergy,

Particle Swarm Optimization is inspired by synergistic effect by

birds,

Ant Colony algorithm is inspired by synergistic effect by ants

and

Fire Flies optimization algorithm is inspired by synergistic effect

by fire flies,

Brain Storm Optimization algorithms inspired by synergistic

effect by us - the most intelligent creature!

1. KeyExpansions — round keys are derived from the

cipher key using Rijndael's key schedule, AES requires

a separate 128-bit round key block for each round.

2. InitialRound 1. AddRoundKey—each byte of the state is combined

with a block of the round key using bitwise xor.

3. Rounds 1. SubBytes — a non-linear substitution step where each byte is

replaced with another according to a lookup table.

4. ShiftRows — a transposition step where the last three rows of the state are

shifted cyclically a certain number of steps.

5. MixColumns — a mixing operation which operates on the columns of the

state, combining the four bytes in each column.

6. AddRoundKey, SubBytes, ShiftRows, AddRoundKey.

Institute of Standards and Technology in 2001

2. The System and the Solution

� When the network cloud is a private system, the existing

encryption might be good enough; however when the

network cloud includes public network, and

� When the drone has the limited power supple, a swapping

based encryption methodology becomes necessary.

� Maintaining several passwords across a number of wireless

networks can be cumbersome.

� An end-to-end pass phrase and time-stamp based encryption

in this case is highly desirable for most end users.

� There are many types of optimization algorithm. We focus

on the brain storm one, because the key space is huge.

3. Encryption Scheme Optimization

Fibonacci was born 1170, a wealthy Italian merchant

A Fibonacci polynomial is defined as the next

number in the sequence being made from the

weighted summation of previous two numbers,

Fn+1(x,y)=xFn(x,y)+ yFn-1(x,y)

If the very first two weights x=y=1, then it is

called original Fibonacci sequence.

5. Summary and Future Work

� The encryption for live video dedicated to the

security communities is different,

� Fibonacci polynomial based on transcendental

number data swapping key generation algorithm fit,

� Its spectrum based brain storm optimized key has

advantage,

� Developmental brainstorming will make it more low

power, low latency and high security.
