Substitution boxes play an essential role in designing secure cryptosystems. With the
evolution of quantum technologies, current data security mechanisms may be broken due to …

In today's technology world, data security has a great importance. Because each data type
has its own characteristics, there are various methods of providing this security. The main …

Recently, Steganography is an outstanding research area which used for data protection
from unauthorized access. Steganography is defined as the art and science of covert …

This paper proposes a triple-layer, high capacity, message security scheme. The first two
layers are of a cryptographic nature, whereas the third layer is of a steganographic nature. In …

Sending image in a plain form has a high risk for the data being vulnerable to steal. Thus,
due to reducing the risk, data security techniques should be implemented. Data security …

Authentication of digital media has been done with the various scheme, one of them is a
digital signature. The main reason the technique of digital signature appears on the …

The security aspect is very important in data transmission. One way to secure data is with
steganography and cryptography. Surely research on this should continue to be developed …

This paper proposed a hybrid method that had been solved both of these issues. We
proposed a combination of Discrete Cosine Transform (DCT) and Haar Wavelet Transform …

This paper uses a novel color image stego-crypto technique to enhance the capacity,
security and robustness of data embedding process. The proposed scheme uses a base64 …

Many people have used the internet in daily communication. The rise of internet data theft
makes the security of data transmission becomes very important. Cryptography and …
