In this paper we propose a new image randomness measure using Shannon entropy over
local image blocks. The proposed local Shannon entropy measure overcomes several …

Network traffic classification is an important tool for network administrators in enabling
monitoring and service provisioning. Traditional techniques employed in classifying traffic do …

The quality of image encryption is commonly measured by the Shannon entropy over the
ciphertext image. However, this measurement does not consider to the randomness of local …

In this work, we classify all templates according to their periods and for each template we
evaluate the exact probabilities using generating functions. Afterwards, we propose a new …

Random sequences and random numbers constitute a necessary part of cryptography.
Many cryptographic protocols depend on random values. Randomness is measured by …

Recently, many scholars have tried to design new security methods inspired by biological
techniques, as DNA, Some of which are in the domains of cryptography and steganography …

The Internet is a medium with low security, so there is a real need for measures to guarantee
data integrity and privacy in the networks and associated computer systems. Cryptography …

The use of key-dependent MixColumns can be regarded as one of the applied techniques
for changing the quality of a cryptographic algorithm. This article explains one approach for …

Many scholars have attempted to use new methods inspired by DNA bio-techniques in the
domains of cryptography and steganography. In this article, a new S-Box was designed …

A cryptographic function with a fixed-length output, such as a block cipher, hash function, or
message authentication code (MAC), should behave as a random mapping. The mapping's …
