“…Public key encryption has several benefits, including strong security protection against adversaries, providing digital signature and eradicating key distribution. However, the encryption/decryption processing speed is slow relative to that of symmetric encryption [54,55]. In this study, we do not use the RSA algorithm but rather AES and hashing algorithms are deployed to improve the security of MODBUS messaging during a communication broadcast.…”

Information technology (IT) security has become a major concern due to the growing demand for information and massive development of client/server applications for various types of applications running on modern IT infrastructure. How has security been taken into account and which paradigms are necessary to minimize security issues while increasing efficiency, reducing the influence on transmissions, ensuring protocol independency and achieving substantial performance? We have found cryptography to be an absolute security mechanism for client/server architectures, and in this study, a new security design was developed with the MODBUS protocol, which is considered to offer phenomenal performance for future development and enhancement of real IT infrastructure. This study is also considered to be a complete development because security is tested in almost all ways of MODBUS communication. The computed measurements are evaluated to validate the overall development, and the results indicate a substantial improvement in security that is differentiated from conventional methods.

“…Several techniques have been used to design the IDS. The intrusion detection policy proposed in [17] monitors the communication between neighboring nodes and finds those nodes that are not working normally. Some general rules are defined to detect such nodes, which are called compromised nodes.…”

“…We technically implement our algorithm and protocol considering the honeypots technique. In contrast to [17], we are not concerned with routing inside the WSN, but in addition to that work we propose a transport and policy algorithm and protocol. We do not inspect the traffic of the intruder (as [19] did) but we consider it to reduce the rate of attacks it can do.…”

Wireless sensor networks (WSNs) are currently widely used in many environments. Some of them gather many critical data, which should be protected from intruders. Generally, when an intruder is detected in the WSN, its connection is immediately stopped. But this way does not let the network administrator gather information about the attacker and/or its purposes. In this paper, we present a bioinspired system that uses the procedure taken by the web spider when it wants to catch its prey. We will explain how all steps performed by the web spider are included in our system and we will detail the algorithm and protocol procedure. A real test bench has been implemented in order to validate our system. It shows the performance for different response times, the CPU and RAM consumption, and the average and maximum values for ping and tracert time responses using constant delay and exponential jitter.

E-HATS is a symmetric key encryption algorithm which encrypts and decrypts a 128-bit data block. E-HATS inherits the simplicity, feistel nature of DES and security analogous to AES. Key Updation is addressed by 16 additional bits in the cipher key. A Dynamic Substitution Rule is used in the substitution step. At the software level, E-HATS exhibits superior avalanche characteristics, achieves a reduction of 7.2% in average encryption time per block and a gain of 10.35% in throughput compared to AES. E-HATS implemented on Artix 7 FPGA platform achieves 79%, 58.24% reduction in hardware and power requirements, respectively compared to AES. E-HATS is not vulnerable to differential and linear cryptanalysis and a brute force attack is 16 P4 times laborious than AES.
