This paper proposes and develops a web attack detection model that combines a clustering algorithm and a multi-branch convolutional neural network (CNN). The original feature set was clustered into clusters of similar features. Each cluster of similar features was generalized in a convolutional structure of a branch of the CNN. The component feature vectors are assembled into a synthetic feature vector and included in a fully connected layer for classification.

Currently, one of the most powerful side channel attacks (SCA) is profiled attack. Machine learning algorithms, for example support vector machine (SVM), are currently used to improve the effectiveness of the attack. One issue of using SVM-based profiled attack is extracting points of interest (POIs), or features from power traces.

The block ciphers modes of operation with internal rekeying mechanisms, used during the encryption of a message to increase their security, have been a subject of analysis in recent years. In this paper, we will analyze the randomness of the sequences generated by two of these modes of operation, which also will be used in the generation of pseudorandom numbers.

—In this paper, we present the dynamic cryptographic algorithms for long states named ACDEL-2D and ACDEL-3D. The first one was inspired by Rijndael and the second one was inspired by 3D, a three-dimensional block cipher. In both proposals, MDS matrices are used alternately on rows and columns of the state and all transformations used in the encryption process are randomly selected depending on pseudorandom sequences.

Cryptographic theory has provided a potentially invaluable notion for cryptographic practice: the idea of provable security. Unfortunately, theoretical work often gains provable security only at the cost of effciency. Schemes like standard RSA are efficient but not provably secured. There are schemes who are provably secured but are not efficient. However, there are encryption schemes, for eg. El Gamal encryption, which are efficient and secured at the same time.
