The characteristics of low correlation, large key space
, high key sensitivity, high entropy, and low time complexity are the main issues for a good image encryption algorithm.
Furthermore, beside keys of [lambda] and z, the other parameters of [alpha], [x.sub.1], and [y.sub.1] are used as additional secret keys to provide a larger key space
. Therefore, the security of the system has been greatly improved.
In our proposed modified AES, the nonlinearity feature increases this difference and therefore, the key space
of searching also increases drastically.
Analyzed brute-force attack by considering key space
Two chaotic maps are used to increase the key space
and security performance of the algorithm.
Oman stands to benefit from this by establishing its own space agency, in collaboration with local education institutes and global partnerships with key space
Its seed space and key space
are larger than [2.sup.512].
From the above calculation we can know that the key space
is large enough to resist exhaustive attacks.
This leads to in-depth coverage of US military space policy through key space
programs and weapons development from the Eisenhower to the Bush administrations.
Summary: DUBAI - Hussain Al Ansari, Vice President, Arab Youth Venture Foundation (AYVF), has been selected to participate in the annual Space Generation Congress, an annual conference bringing together top young minds to focus on key space
This project will demonstrate responsive, high precision laser and optical tracking of space debris, improved space situational awareness for key space
assets, and fully remote and automated operation of a high performance laser tracking system."
The key space
is much larger than the key space
of 1D CA-based system.
