key space

The total number of possible values of keys in a cryptographic algorithm or other security measure such as a password. For example, a 20-bit key would have a key space of 1,048,576. See binary values, key length and key fingerprint.

To increase the security key space, we first run the Logistic and the Chebyshev chaotic systems starting from two random initial keys with enough iterations, and then put the result of one of them into the other with several other iterations, finally we take the results as initial conditions of chaotic maps.
In order to expand secret key space further and make the encrypted information totally invisible, we proposed an encryption method combining CGH and 2D-SLMM in this paper.
Though the XOR operation, S-boxes, and the shifting in g function, shown in Figure 3, are providing the confusion characteristics to the algorithm, the reverse engineering process can easily get back to the original key space. Moreover, the biased inputs in the key space reveal the differences between the words to partially gain the key space.
But, the authors did not express their works on security issues such as brute-force attack, key space analysis, histogram analysis, pixel correlation, chaotic test, and entropy.
But they have small key space which in turn suffers from brute force attack.

Key Space. The key set parameters of CPRNG include the initial conditions X(0), Y(0), the parameters set [[[tau].sub.L], [[delta].sub.L], [[delta].sub.R], [mu], [gamma]}, and the matrix A = ([[alpha].sub.i,j]).
In order to know that the encrypted image can resist the exhaustive attacks it should be proven that it has a large key space and high sensitivity to initial conditions.
Although Part 1 and Part 4 are very interesting, I especially liked Parts 2 and 3 with their intimate reviews of key space pioneers and the science/technology being developed for mankind's initial travels and exploration of space.
