Lattice-based cryptosystems have some advantages compared to other cryptosystems based on the hardness of factoring, DLP, and so on.
This paper proposes a new encryption approach for RSA cryptosystem based on three moduli set {2n+2,2n+1,2n} with a common factor.

Some cryptosystems for example RSA system with four thousand bit keys are considered useful to protect information from classic computers attacks, but are absolutely not safe against attacks implemented using quantum computers.
The Paillier cryptosystem produces this k and it is the basis of this phase.
We believe these advantages are mainly from the parallel pipeline, the multilevel index/length code-words, and the chaotic cryptosystem.

Clearly, no matter how similar the two input images are, a good image cryptosystem should produce outputs with NPCR and UACI values ideally being equal to those of two random images, which are given by
The revocation mechanism of ABE schemes is more complicated than that of traditional public key cryptosystem or IBE schemes [40, 62-65].
