Mobile ad-hoc network is an interesting network, which is classified as an autonomous system. These types of networks are constructed based on low capacity wireless links, without having a centralized infrastructure system. Lack of central monitoring system makes it so vulnerable to an insider attack. These attacks consist of two main categories;false data and false route attack. An efficient intrusion detection system (IDS) should have a good understanding about the categories. It can be defined by comparison between (true positive network throughput/false throughput) and the packet delivery ratio. This paper, DNACK is proposed based on digital signature and standard method of Negative Acknowledgment, which is a new method of false data detection in case of en-route filtering IDS. DNACK members can detect both kinds of insider attacks, a false data (false data injected and false modified messages) and false route attacks (packet dropping and flooding attack), regards to DNACK characteristic. The false data will be detected based on source digital signature by upcoming member and the routing attacks, will be monitored by the last member. The network efficiency shall be guaranteed by using of DNACK because of the high percentage of Packet delivery and the minimum of false throughput.

On the Internet, most financial applications apply public key cryptography to verify users' identities, manage their digital assets, authenticate and authorize them, etc. In a blockchain system, this model is crucial to keep the system working, since there are no intermediaries or a central database for management. Commonly, users can manage their key pair using the blockchain wallet, also known as 'crypto wallets.' In practice, the user has to keep track of many key pairs for each asset, which is inefficient. We use a hierarchical deterministic wallet (HD wallet) to solve this problem, which can derive hundreds of child wallets from a single master key-pair. Currently, there are already multiple protocols for an HD wallet for Secp256k1 while those for Ed25519 are neither well-known nor well developed. In this thesis, we will try to analyze and build an HD wallet for Ed25519 signature schema.

In the current environment, there are only a limited number of third-parties that general users can trust in terms of authentication and verification. Often, the self-acclaimed independent third-parties are the parties from where information outflow occurs. While current public key encryption systems have numerous algorithms that have been protecting confidential data for several years, these systems are often met with hardware difficulties for information protection on the Internet and commercial applications. In order to meet the various needs of the environment, often several cryptography modules are combined or merged to achieve the effect of covering each others' deficiencies. This is a very common practice. The proposed method in this article is applicable for preventing information outflow with the introduction of third parties during a bi-party communication, in circumstances where bi-party communication is met with network environment difficulties, and also when the third party is not a trusted controller, or there are no controllers at all. While current systems operate on the back of trusted third-party administrators as is a common security mechanism for managing the public key and confidential data, often even with management, there are still probabilities of insecurity that threaten system security on the whole. To prevent this and also adapt to environment needs, the proposed method combines the grey system theory with the ECC method. This method can verify the credibility of senders' identity when the legitimate third party is no longer trusted, thus preventing malicious third-party intrusions. The concept of this method is based on the well-known digital signature algorithm (DSA) concept from which the Diffie-Hellman Key Agreement mechanism is derived to manage a common conference key in a mutual communication, agreement. When the user can communicate mutually between themselves without the need for a third-party intermediary, the solution to interv

Security is necessary for performing the effective data communications in internet and cloud environment. The data security in cloud is becoming very challenging task due to the presence of huge volume of cloud users. Even though, the various secured cloud data storage mechanisms are available and tried to fulfill the current requirement in terms of security level and efficiency. However, the available works are not obtained the enough security level and the efficiency while storing and sharing the data in cloud. For this purpose, this work proposes a new secured storage method for providing data security to store the data securely in cloud. The proposed system consists of three different algorithms for performing prime number generation, digital signature creation for generating keys, encryption, decryption and authorization. Here, a new technique to find a co-prime number which is used to generate keys in key generation process and also useful for performing encryption and decryption process. Moreover, a new key generation technique is also introduced for elliptic curve cryptography and digital signature algorithm using polynomial congruence for performing key generation process securely. In addition, a new elliptic curve and polynomial congruence based encryption/decryption algorithms for performing data encryption and decryption in the process of data storage and communication. Finally, the user authenticity is verified by the proposed digital signature algorithm in this work. The experiments have been conducted for evaluating the proposed secured storage and communication system and proved as better than others in terms of efficiency and security level.

An Efficient Hardware/Software Co-Design for FALCON on Low-End Embedded Systems

We propose in this paper an efficient FALCON accelerator called EFX based on a HW/SW co-design where FALCON is a post-quantum cryptographic (PQC) scheme tailored as a digital signature algorithm (DSA). Our findings reveal that FALCON exhibits unique characteristics and structures which distinguish it from other PQC-DSAs. A key finding is that, unlike its counterparts, FALCON doesn't prioritize a single, time-consuming task;instead, it processes a variety of tasks with comparable execution times. Consequently, the conventional methods focusing on accelerating dominant few tasks, which are generally effective for other algorithms, prove less efficient for FALCON, especially concerning the minimization of the silicon area used. To overcome this, we strategically focus on the granular optimization of lower-level operations rather than on broader functional segments, aiming to boost performance while conserving hardware space. Moreover, to mitigate the potential degradation due to limitation of hardware resources, we have implemented a pipelined execution strategy for the FALCON functions and refined the sampling function-a critical task that is challenging to accelerate due to inherent sequential algorithm-enabling it to run concurrently on both software and hardware, thus reducing latency. Our hardware design, synthesized at 300MHz using Samsung's 28nm and 45nm process technologies, demonstrates superior performance in generating FALCON signatures, with a 3.58x improvement in clock cycles over an existing hardware accelerator. EFX occupies 38K um(2) and 74K um(2) for 28nm and 45nm processes, respectively, comparatively small compared to other PQC accelerators.

To provide authentication to the Diffie-Hellman key exchange, a few integrated key exchange schemes which provide authentication using the DSA signature have been proposed in the literature. In this letter we point out that all of the previous Diffie-Heliman-DSA schemes do not provide security against session state reveal attacks. We also suggest a strong Diffie-Hellman-DSA scheme providing security against session state reveal attacks as well as forward secrecy and key independence.

Batch verification is a method to verify multiple signatures at once. There are two issues associated with batch verification. One is the security problem and the other is the computational speed. In 1998, Bellare et al. have proposed an approach called small exponents test, to preserve the security of batch verification of a digital signature algorithm (DSA) variant. In this letter, we propose an efficient scheme to speed up DSA batch verification. Our scheme does not need to compute modular inverse and at the same time, the security is preserved. We have included the performance evaluation to compare Computational time between our scheme and the existed DSA batch verification. (c) 2004 Elsevier Inc. All rights reserved.

In the autonomous driving environment, each vehicle performs numerous signing and verification while sending and receiving BSMs (Basic Security Messages) in real-time. We present an optimized CRYSTALS-Dilithium software which can quickly process each signing and verification in parallel using embedded Graphic Processing Unit. For efficiency, we propose several optimization techniques such as dummy operation-based warp divergence reducing technique, parallel implementation NTT (Number Theoretic Transform)-based polynomial multiplication, optimization of rejection sampling process using rejection sequence table, and so on. The proposed CRYSTALS-Dilithium software provides a performance improvement of up to 19.41 times compared to the Dilithium Software on CPUs on NVIDIA Jetson AGX Xavier which is an off-the-shelf autonomous vehicle OBU (On-Board Unit).
