Wireless Sensor Networks (WSN) is arising as a potential computing platform in diverse zones such as weather forecasting, modern robotization, medical health care, and military systems, etc. Since the sensors are constantly gathering information from the actual world and communicate with one another through remote connections, keeping up the security and protection of WSN communication is a prerequisite. In this paper, safe confirmation and key organization scheme dependent on Elliptic Curve Cryptography (ECC) has been suggested to make sure about information/picture transmission in WSNs. The scheme proposed in this paper is protected, competent, and appropriate for providing sensor technology based IoT services and applications. The protocol provides all the security features such as mutual authentication, confidentiality, data integrity, perfect forward secrecy, fair key agreement, etc. and is secure against hello flood attack, DoS attack, man-in-middle attack, etc. Simulation software AVISPA has confirmed the safety of the protocol for the known assaults. The performance analysis ensures the superiority of the projected proposal over the existing schemes.

Image encryption based on elliptic curve cryptosystem
International Journal of Electrical and Computer Engineering (IJECE), 2021
Image encryption based on elliptic curve cryptosystem and reducing its complexity is still being actively researched. Generating matrix for encryption algorithm secret key together with Hilbert matrix will be involved in this study. For a first case we will need not to compute the inverse matrix for the decryption processing cause the matrix that be generated in encryption step was self invertible matrix. While for the second case, computing the inverse matrix will be required. Peak signal to noise ratio (PSNR), and unified average changing intensity (UACI) will be used to assess which case is more efficiency to encryption the grayscale image.

INTRODUCTION Cryptography is a strategy for putting away and transmitting information in a verified structure with the goal that lone proposed client can peruse and process it [1]. It includes encryption and decoding of messages.Encryption is the way toward changing over plain information into cipher text and decoding is the way toward getting back the first message from the encoded content. There are many uses for Cryptography such like: protect e-mail information, credit card information. Indeed it provides confidentiality, authentication, Integrity and non-repudiation [2]. Elliptic curves are arithmeticcurves which have been studied by numerous mathematicians for quite a while [3]. One of its most important applications appeared in 1985, where Neal [4] and Miller [5] independently proposed the public key cryptosystems based on elliptic curve they named elliptic curve cryptosystem (ECC). From that point forward, numerous scientists have gone through years concentrating the quality of ECC and improving procedures for its execution. In ECC a 160-bit key provides the same security as compared to the traditional cryptosystem RSA [6] with a 1024-bit key, in this way it can reduced computational cost or processing cost [7]. The security of ECC depends on the difficulty of solving elliptic curve discrete logarithm problem (ECDLP) [8]. Digital images are an appealing information type that offers a far reaching scope of utilization. Any clients are keen on actualizing content security strategies to their pictures [9]. Recently, many image encryption techniques have been proposed to verify interactive media data before transmission over insecure channels such like [10, 11]. Elliptic curve cryptosystem is a superior strategy to transmit the picture safely [12]. The matrix that appears to have an endless interest for mathematicians, is symmetric and definite, it is The Hilbert matrix, with (i, j) element
Elliptic Curve Cryptography (ECC) for Security in wireless Sensor Network
2012
This paper discusses different issues of Wireless S ensor Network (WS N) and the relevance of the Elliptic curve y cryptography. S ecurity in WS N is a greater challenge in WS N due to the processing limitations of sensor nodes and nature of wireless links. Extensive use of WS Ns is giving rise to different types of threats. To defend against the threats proper security schemes are required. Traditionally security is implemented through hardware or software and is generally achieved through cryptographic methods. Limited area, nature of links, limited processing, power and memory of WS Ns leads to strict constraints on the selection of cryptographic techniques. Elliptic Curve Cryptography (ECC) is the best candidate due to its smaller key size. High security despite of smaller key size results in area and power efficient crypto systems.
A Review: Elliptical Curve Cryptography in Wireless Ad-hoc Networks
As the wireless industry exploding, the need for security is also exploding. Both for secure communication between two parties, Web transactions and for secure messaging, efficient Public Key Infrastructure is needed. Elliptic Curve Cryptography (ECC) is a recent branch of cryptography based on the arithmetic of elliptic curves and the Elliptic Curve Discrete Logarithm Problem (ECDLP). Elliptic curve cryptographic schemes are public-key mechanisms that provide encryption, digital signature and key exchange capabilities. ECC provides better security for wireless ad-hoc networks compare to other cryptographic techniques because of its small key size. In this survey, we are enhancing the role of elliptical curve cryptography in wireless ad-hoc networks.

Image Encryption and Decryption Using Elliptic Curve Cryptography
2014
In today’s world image plays an important role in everyone’s life. The, security of image is required while transferring them across the network. Various encryption and decryption algorithms are available to protect the image from unauthorized user. RSA and Diffie-hellman key exchange provide a good level of security but the size of encryption key in these two is a big problem. ECC is a better alternative for public key encryption. It provides equal security with smaller key size. In this paper the image which is considered to be in the form of a grid, is first transformed on an elliptic curve. These points or coordinates are then encrypted and send to the recipient. At the receiver end decryption algorithm is used to convert the encrypted image into the original image. Brute force attack is infeasible for ECC because of the discrete logarithmic nature of elliptic curves. This paper presents the technique to encrypt and decrypt the digital image(BMP) from Elliptic Curve Cryptography.

Public-key cryptography has been at the center of online communication and information transfer for decades. With computing power growing at an exponential rate, a number of most widely used encryption schemes are beginning to show their limits. Since these systems may appear on low computing power devices like mobile phones, or chips, it’s become essential to make protocols such that we will reach the same level of security without spending considerable computing power putting up the system in the very first place. Elliptic curve cryptography (ECC) provides an exciting alternative to RSA, and has shown to be lot more efficient in terms of key size. Mobile Ad-Hoc Network’s (MANET’s) is the system, wherein wireless mobile nodes are dynamically self-organized in an arbitrary temporary network topologies that enables people and networks to internetwork with no pre-existing infrastructure. ECC is an alternative mechanism for implementing the public key cryptography and its advantage is that, it has higher efficiency and better scalability. Wireless devices need to utilize Public Key Cryptography in order to improve immunity in security issues such as, authentication, key exchange and it requires a novel solution to overcome them, which are provided by ECC.

The point of this paper is to create a basis for apply efficient encryption schemes in wireless communications and in devices with low computing power and resources. Elliptic Curve Cryptography (ECC) fits well for an efficient and secure encryption scheme. It is more efficient than the traditional integer based RSA schemes because ECC utilizes smaller key sizes for equivalent security. A comparative study of ECC with RSA is made in terms of key size, computational power, size of data files and encrypted files. Also, another aim is to design an API to implement ECC encryption /decryption algorithm.
