Shared Secret Key

One of the modern applications of cryptography is the sharing of secrets in occurrence keys. Indeed, the need to establish a shared secret key in a multi-user system clearly remains a major problem of trust between users. Therefore, one solution is to share this secret key between users seamlessly. New technologies embedded systems such as sensor networks provide an ideal platform for sharing secrets. In addition, elliptic curves offer an adequate solution for reducing the size of keys, which is suitable for embedded systems. In this article, we propose an approach for sharing a secret leaked in a QR code adapted for a multiuser system, where each user has the ability to verify its share by an access structure. The system allows a recovery without loss of data in this case the QR code used.

Security is critical in a home gateway environment. Robust secure mechanisms must be put in place for protecting information transferred through a central location. In considering characteristics for the home gateway environment, this paper proposes a bundle authentication mechanism. We designed the exchange mechanism for transferring a shared secret key. This transports a service bundle safely in the bootstrapping step, by recognizing and initializing various components. In this paper, we propose a bundle authentication mechanism based on a MAC that uses a shared secret key created in the bootstrapping step. In addition, we verify the safety of the key exchange mechanism and bundle authentication mechanism using BAN Logic. From the verified result, we achieved goals of authentication. That is, the operator can trust the bundle provided by the service provider. The user who uses the service gateway can also express trust and use the bundle provided by the operator.

Shared Secret Key

Light fidelity (Li-Fi) is a technology that is used to design a wireless network for communication using light. Current technology based on wireless fidelity (Wi-Fi) has some drawbacks that include speed and bandwidth limit, security issues, and attacks by malicious users, which yield Wi-Fi as less reliable compared to LiFi. The conventional key generation techniques are vulnerable to the current technological improvement in terms of computing power, so the solution is to introduce physics laws based on quantum technology and particle nature of light. Here the authors give a methodology to make the BB84 algorithm, a quantum cryptographic algorithm to generate the secret keys which will be shared by polarizing photons and more secure by eliminating one of its limitations that deals with dependency on the classical channel. The result obtained is sequence of 0 and 1, which is the secret key. The authors make use of the generated shared secret key to encrypt data using a one-time pad technique and transmit the encrypted data using LiFi and removing the disadvantage of the existing one-time pad technique.

Shared Secret Key

RFID system is facing the serious problems of private security, which mainly consists of the leakage of tag sensitive information, tracking and monitoring spitefully the carrier of mobile tag. This paper constructs a coordination protection mechanism of tag private information by a variety of reader-writer, which solves the two questions mentioned above. Firstly, a trust-security mechanism used to ensure that the readers in system are trustful. Next, via intercommunication of the readers, the secret key, which is produced by the tag-charged reader, is divided and distributed to the various readers in system. The test result shows that attackers cannot gain the shared secret key from various readers, and he/she could only read an encoded data, thus the security of private information in tag is guaranteed. Additionally, a set of readers use coordination-protection mechanism, which is an efficient way to improve the expandability of the system.

Shared Secret Key

A double-key based stronger secured electronic message transaction system has been designed and developed using Python programming language by performing encryption-decryption process. To do this, simple cryptographic encryption and decryption techniques are used with two keys avoiding vulnerabilities of a single key. First, the intended message is encrypted with the private key of sender (PRa) and the output is again encrypted with a shared secret key (K1) that generates ciphertext. The output ciphertext is again encrypted with another shared secret key (K2) that generates a code that serves as Message Authentication Code (MAC), which is concatenated with the ciphertext. And again encrypted them with shared secret key K1 that produced final ciphertext which is to be send to the intending recipient. The shared secret keys K1 and K2 are getting from the key distribution center (KDC). In the receiving end, receiver first decrypts the received information with the shared secret key K1 that gives the ciphertext and MAC of the ciphertext, and then decrypts only the MAC to generate a new ciphertext′and compare the new ciphertext′ with the received ciphertext that ensures the ciphertext authentication as well as message authentication; if ciphertexts are found same, then the ciphertext is decrypted with shared secret key K2 and again is decrypted with the sender’s public key (PUa) and retrieve the message; otherwise discarded. This proposed system ensures the stronger authenticated message transactions among the communicants. Finally, a comparative study with the existing systems has also been performed and measured stronger security. This technique can be applied for any secured electronic information transfer system with stronger security services. GUB JOURNAL OF SCIENCE AND ENGINEERING, Vol 6(1), Dec 2019 P 75-80

Abstract Cryptography is related and referred to as the secured transmission of messages amongst the sender and the intended receiver by ensuring confidentiality, integrity, and authentication. Diffie – Hellman (DH) key exchange protocol is a well-known algorithm that would generate a shared secret key among the sender and the intended receiver, and the basis of cryptosystems for using public and private key for encryption and decryption process. But it is severely affected by the Man in the Middle (MITM) attack that would intercept and manipulate thus eavesdropping the shared secret key. This paper proposes a model of integrating the public-key RSA cryptography system with the DH key exchange to prevent the MITM attack. The performance of the proposed work has been compared to the DH Key Exchange algorithm as well as RSA Cryptosystem to conclude for effectiveness of the proposed model.

Provably Secure

Abstract In this paper, a new key-agreement scheme is proposed and analyzed. In addition to being provably secure in shared secret key indistinguishability model, the scheme has an interesting feature: while using exponentiation over a cyclic subgroup to establish the key-agreement, the generator of that subgroup is hidden to secure the scheme against adversaries that are capable of solving the Discrete Logarithm Problem, which means that the scheme might be candidate as a post-quantum key exchange scheme.
