Accepted paper in International Computer Engineering Conference (ICENCO)


NISC Center would like to congratulate Dr.  Ahmed  G.  Radwan, for his accepted papers in 11th  IEEE International Computer Engineering Conference (ICENCO), Egypt, 2015.

[1] Wafaa  S.  Sayed,  Ahmed  G.  Radwan,  Hossam  A.  H.  Fahmy,  “Design  of  a Generalized  Bidirectional  Tent  Map  Suitable  for  Encryption  Applications,”  11th  IEEE  International Computer Engineering Conference (ICENCO), Egypt, 2015.


The discrete tent map is one of the most famous discrete chaotic maps that has widely-spread applications. This paper investigates a set of four generalized tent maps where the conventional map is a special case. The proposed maps have extra degrees of freedom which provide different chaotic characteristics and increase the design flexibility required for many applications. Mathematical analyses for generalized positive and mostly positive tent maps include: bifurcation diagrams relative to all parameters, effective range of parameters, bifurcation points. The maximum Lyapunov exponent (MLE) is also calculated to indicate chaotic behavior. Various scales of the bifurcation diagram are discussed for each generalized map as well as system responses versus the added parameters.
