What is AES?
• AES, or Advanced Encryption Standard, is a widely
used encryption algorithm in information security. .
• It was established by the National Institute of
Standards and Technology (NIST) in 2001 and is
used to secure electronic data.
• AES is a symmetric key encryption algorithm,
meaning the same key is used for both encryption
and decryption.

13. 13
Methodology
• The proposed work deals with the
transmission of data from the
sender to the receiver in a
computer network in a secure
manner.
• This paper proposes a
cryptographic algorithm that is
termed as Modified Advanced
Encryption Standard (MAES)
algorithm for this improving
security in data transmission.
• The sender sends the message in
the form of a plain text. This is
converted into a cipher text.
• Random keys are generated for
encrypting and decrypting the
text.
• The generation of the keys is
randomized by employing the
Flower Pollination Algorithm
(FPA).
• This algorithm plays a vital
role in the enhancement of
security of the cryptographic
algorithm.
• At the receiver’s side the
plain text is retrieved from
the cipher text.
• The block diagram of the
proposed system is illustrated
in figure .

Results
•The results that were obtained using the MAES was
compared with the other cryptographic algorithms.
•The algorithms that were taken for the comparative
analysis were the DES, Rivest Cipher (RC4) and Blowfish.
•It can be observed that as the file size increases, the
encryption time sees an elevation in its values.
•The different files sizes that are taken for the analysis are
10,000 KB, 20,000KB, 30,000KB, 40,000 KB and 50,000 KB.
•The Blowfish algorithm takes the maximum time for
encrypting a file with a specified file size.

17. 17
Methodology
• Selective encryption is a technique
for encrypting only parts of a
compressed video stream to reduce
computational complexity Selective
encryption is not a new idea.
• It has been proposed in several
applications, especially in
multimedia system.
• Selective encryption can be used to
reduce the power consumed by the
encryption function for digital
content.
• Since particular parts of the bit
stream are encrypted, selective
encryption can also enable new
system functionality such allowing
previewing of content.
• For selective encryption to work,
we need to rely on a
characteristic of the compression
algorithm to concentrate
important data relative to the
original signal in a relatively small
fraction of the compressed
bitstream.
• In our selective encryption, an I-
Frame bit stream of H.264/AVC,
bitstream is encrypted to
minimize computational
complexity or provide new
functionalities for uses of the
encrypted bit stream while at the
same time providing reasonable
security of the bit stream.

18. 18
Results
•AES may, as all algorithms, be used in different ways to
perform encryption.
•Different methods are suitable for different situations.
•It is vital that the correct method is applied in the correct
manner to each and every situation, or the result may well
be insecure even if AES as such is secure.
•It is very easy to implement a system using AES as its
encryption algorithm, but much more skill and experience
are required to do it in the right way for a given situation.
•To describe exactly how to apply AES for varying purposes
is very much out of scope for this paper.

19. 19
Conclusion
•This paper a proposed system to study video data security by a review and investigation on multimedia security
technologies and successful to achievement main above goals, which enhancing the Selective Video Encryption Using
Computation between H.264/AVC and AES Encryption Algorithm H.264/AVC bit-stream was able to be consumed in a form
of the partial bit-stream converted by extraction process.
• At this time, each bitsrtream of the H.264/AVC bitstream should be consumed by a trusted user who has the rights for
accessibility. The requirements for H.264/AVC encryption and decryption are as follow.
•The encryption considers the security, time efficiency, format compliance and error robustness, basically. The I Frame
encryption being the basis of P-frame and B-Frame in H.264/AVC bit-streams should be more securely protected than the
enhancement layers.
