The basic concept of wireless video streaming system, the main requirements from the law enforcement communities and related encryption algorithm of the wireless system are described. The major challenge in this research area is providing a low computation algorithm that runs easily on an embedded Java application, within pre-optimized key space. The key space is optimized under the object of minimizing the standard deviation of the spectrum of the key. Due to the large space of the key, the brain storm optimization is used to rule out the likely weak key set.

4. 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!

5. 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.

6. 2. The System and the Solution

7. 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.

9. 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.

14. 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.
