Encryption algorithms

The paper proposes a type of block cipher algorithm based on cryptographic hash function and public key cryptography. The algorithm proposed here is capable of verifying the origin and integrity of the encrypted message. On the other hand, establishing a shared secret key between the sender/encryptor and the receiver/decryptor can be done for each message separately.

The information age has seen the development of electronic pathways that carry vast amounts of valuable commercial, scientific, and educational information between financial institutions, companies, individuals, and government organisations. Unfortunately the unprecedented levels of access provided by systems like the Internet also expose this data to breaches of confidentiality, disruption of service, and outright theft. The cryptlib security toolkit provides the answer to this problem. A complete description of the capabilities provided by cryptlib is given below.

The rapid growth of electronic communication means that issues in information security are of increasing practical importance. Messages exchanged over worldwide publicly accessible computer networks must be kept confidential and protected against manipulation. Electronic business requires digital signatures that are valid in law, and secure payment protocols. Modern cryptography provides solutions to all these problems. This book originates from courses given for students in computer science at the Georg-Simon-Ohm University of Applied Sciences, Nurnberg.

The article proposes a public-key cryptographic scheme based on the ElGamal algorithm. This scheme can perform security functions and authenticate the origin and integrity of the encrypted message simultaneously. Moreover, the proposed scheme is also used as the basis for developing an algorithm to establish a shared secret key for symmetric key cryptosystems.

This paper presents a protocol to enhance the secrecy of exchanging symmetric key and the flexibility of updating the partially reconfigurable embedded system over the Internet. The proposed protocol uses an asymmetric encryption algorithm to protect symmetric encryption keys from thefts and tampers over a transmission line.

With the rise of the Internet of Things (IoT), the risk of information security is increasing. There have been many proposals for IoT security, however, so far, there is not truly effective and comprehensive solution. The study aims at lightweight encryption, with the basic goal of reducing the loops of encryption algorithms, reducing the computing requirements, and energy consumption of the system while ensuring safety, and integrating into new Protocols of IoT networks and weak resource devices.

—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.
