Mr Nashwan Alromema presented a seminar about A NOVEL CHAOTIC
ENCRYPTION SCHEME FOR COLOR IMAGE DATA" at Computing and Information
Technology Faculty in Rabigh on Monday 17/10/2011 at 12:00 noon at new
FCITR meeting room. FCITR Dean Dr. Sami Halawani attended the seminar
with the faculty members.
The following is a brief of the seminar:
In image
cryptography, recently numbers of effective chaos-based image encryption
schemes have been proposed. These encryption schemes are structured as
permutation and diffusion stages performed alternatively. In this
project we will propose an encryption scheme for encrypting colored
image data. This encryption scheme is based on chaotic confusion, where
every pixel in the image will be first extracted to its RGB triple,
encrypted, and prepared to be sent in unsecured channel. Selective key
should be presented during the encryption process. This key is in the
form of another chosen image with the same size of the plain image that
we intend to encrypt. Image encryption scheme introduced here is based
on chaos’s method, which is applied on RGB component of the image pixel.
A chaos-based cryptosystem scheme will be proposed in order to reduce
the encryption/decryption time and achieve high level of security.
