(2) In order to ensure the safety of the students' information, the fingerprint characteristic value is encrypted and transmitted, using the improved AES encryption algorithm
, which has the same security guarantee with traditional AES algorithm but reduces the required time for encryption.
In recent years, combined with the dual advantage of the DNA molecule and chaotic systems, an image encryption algorithm
based on DNA molecules and chaotic systems is presented.
In paper , to evaluate the performance of the encryption algorithm
for text files, it uses AES, DES and RSA algorithm and the parameters such as computation time, memory usage, and output bytes are considered.
This shows that the correlation between the encrypted image after the adoption of this encryption algorithm
and the original image is very low.
In this paper, along the chaos-based pipeline, we propose an image encryption algorithm
based on the cross diffusion of two chaotic maps, namely the Logistic map and the Chebyshev map.
The fourth type of encryption algorithm
is called blow fish, which is being used very commonly and introduced by Bruce Shenier (Schneier, 1993; Kazys, 2015).
What these governments are asking for would likely require tech companies to weaken the encryption algorithm
to make it easy for law enforcement to break, or weaken how that encryption algorithm
is implemented to make it easy for law enforcement to bypass.
The Advanced Encryption Standard (AES) is a symmetric encryption algorithm
and one of the most secure.
In addition, the vulnerabilities proved on AES encryption algorithm
or that liked to error propagation caused by CBC mode make its security in the critical situation.
Multifarious chaos-based image encryption algorithms
have been developed up to now, such as in [1-6]; however a few of them have referred to the image encryption algorithm
based on fractional discrete chaotic map accompanied with Elliptic Curve Cryptography (ECC).
Therefore, traditional methods such as advanced encryption standard (AES), data encryption standard (DES), or international data encryption algorithm
(IDEA) are not effective options for image encryption [3, 4].
