“…It is worth mentioning, that swarm intelligence algorithms such as particle swarm optimization [18], firefly algorithm [19], and bird mating optimizer [20]. can be used for cryptoanalysis of Vigenère cipher and recently, there are a number of swarm intelligence algorithms have been applied for that purpose such as [21]- [24].Finally, it is noticed that neural networks [25], [26] which is a typical model for machine learning and application is used also for cryptoanalysis of Vigenère cipher [27].…”

Nowadays, as communication and network technologies evolve in modern life, ensuring the confidentiality of a cryptography system has become a critical requirement. The Vigenère cipher is attracting the attention of cryptography specialists, although the Vigenère cipher algorithm has a problem. The problem is due to a repeating encryption key. As a result of the multiple cryptographic approaches described in the literature, this paper proposes a novel encryption strategy for safe and secure data exchange by utilizing a new key generation process. The proposed encryption approach avoids the issue of repeating keys. Additionally, the classic Vigenère cipher encrypts the plaintext using a 26x26 Vigenère table, the researcher modified the original Vigenère table to 95x95, which adds more potential letters, mathematical symbols, numerals, and punctuation to a standard QWERTY keyboard layout. Additionally, the researcher added case sensitivity. To observe the performance of the proposed method, the index of coincidence and entropy have been calculated. The obtained results confirm the high performance of the proposed algorithm in comparison to the other algorithms used in this paper. The primary goal of this paper is to make cryptanalysis extremely complex and to promote data security.

“…ECC can use elliptic curves to implement cryptography algorithms based on discrete logarithm problems and ElGamal algorithms in an efficient way [6], [7]. Elliptic curve random generator has been defined by National Institute of Standard and Technology (NIST) as a method of grouping random digits based on curves [8]. Unlike other cryptosystems that encrypt and decrypt messages directly, be it text or image, elliptic curve cryptosystem (ECC) is capable of encrypting and decrypting only points on the elliptic curves [7].…”

Elliptic curve cryptography (ECC) remains the best approach to asymmetric cryptography when it comes to securing communication among communication partners in low-computing devices such as wireless sensor networks (WSN) and the Internet of Things (IoT) due to its effectiveness in generating small keys with a strong encryption mechanism. The ECC cuts down on power use and improves device performance, so it can be used in a wide range of devices that don't have a lot of resources. However, most of the existing ECC implementations suffer from implementation flaws that make them vulnerable to cryptanalysis attacks. In this study, flaws in the existing implementation of ECC are identified. A new scheme where the identified flaws are remedied was developed. The results of the security analysis show that the new scheme is an indistinguishable authenticated adaptive chosen ciphertext attack (IND-CCA3), resistant to malleability and man-in-the-middle attacks (MIMA). The results of comparative security analysis show that the mapping scheme employed in the new scheme maps any blocks of plaintext to distinct points on an elliptic curve, which makes it resistant to all attacks that the existing schemes are vulnerable to without having a negative effect on its encryption and decryption time, throughput, or power consumption.

“…But, the RSS is not aware of updates in link quality in experiments [25]. Link quality estimation metric, as well as the required number of packets, is used for evaluating link quality through calculating the ratio of the transmitted as well as retransmitted packets to the amount of effectively obtained packets in a window of communication occurrence [26]. Elliptical curve cryptography (ECC) is an successful for securelytransferdata and improving the receiver end in asymmetric cryptosystems [27].…”

The cuckoo search (CS) technique is applying to discover the optimal route from source to destination. The main objective of this work is to offer suitable solutions for getting better the optimal routing and communicating the data via reliable sensor nodes. This CS optimization method not capable for managing the diversity of the solutions. To solve this issue, we use the CS technique to hybridize it with the hill climbing (HC) technique to minimize the probability of early convergence. This approach introduces a fusion of CS and HC techniques (CSHC) based optimal forwarder selection and detect the Intrusion in wireless sensor network (WSN) . Here, a Bayesian thresholding method is predict the received signal strength and link reliability parameter for identifying intrusion in the network. The hill - climbing technique is able to attain the best solutions in a smaller period than other local search techniques. In CSHC, the optimal forwarderis selection by fitness function. This fitness function is computed based on sensor node lifetime, sensor link reliability, and buffer availability. In this app roach, the experimental results suggest that the CSHC for improving 35% throughput and minimizes the 23.52% packet lossescompared to the baseline approaches.
