To ensure the security of sensitive data, elliptic curve cryptography (ECC) is adopted as an asymmetric method that balances security and efficiency. Nevertheless, embedding messages into elliptic curve (EC) points poses a significant challenge. The intricacies of this process can greatly affect the overall security and efficiency of the cryptosystem, reflecting security vulnerabilities observed in many existing schemes that utilize ElGamal ECC-based encryption. In this paper, we introduce an innovative hash-based technique for securely embedding messages into EC points before encryption. A random parameter and a shared secret point generated through the EC Diffie–Hellman protocol are used to bolster the scheme’s security. The security of the proposed method is evaluated against various attack models; moreover, the complexity, and sensitivity of the encryption scheme, as well as its inputs, are analyzed. The randomness assessment of the ciphertext was performed using the NIST statistical test suite. Additionally, we propose a mechanism to ensure the integrity of the message by securely appending a tag to the ciphertext. As a consequence, a comprehensive analysis of our scheme demonstrates its effectiveness in maintaining data security and integrity against various attack models. The algorithm also meets more criteria such as the strict avalanche criterion, linear complexity, and operability.

In information security the following security parameters like, integrity, non repudiation and confidentiality, authentication must be satisfied. To avoid thievery of organization resources it needs be secured in more efficient way and there is always demand for different levels of security attacks include virus, brute force and Eveadroper in business that organizations make use of voice biometrics an attractive low-cost. Voice biometrics is the cheapest among the other biometrics and used all levels for management to buy readily available metric and it is the way of identifying individuals remotely with high level of accuracy. In this work, we have been designed a new password-authentication approach that provides security using voice biometrics for authentication and uses the device itself into an authenticator which uses voice itself as its passwords and we are primarily interested in keys that can be temporally reproduced on the same device from the same user's voice. Public and private keys are generated randomly from the user's voice and stored in the voice file (.wav). This Method uses voice recognition, include the operation of register (recording feature) or voice prints and storing of one or more voice passwords into the database. It uses ECDSA to perform the authentication process that matching the voice sample with the database. The recognition, entity makes the database to decide that the sample is matched to perform an operation or not. Our proposed approach generates cryptographic keys from voice input itself and this algorithm developed an adhoc basis. It can effectively defend attacks specially brute force attack in system networks.

In this paper describes the basic idea of elliptic curve cryptography (ECC) as well as Vigenère symmetry key. Elliptic curve arithmetic can be used to develop elliptic curve coding schemes, including key exchange, encryption, and digital signature. The main attraction of elliptic curve cryptography compared to Rivest, Shamir, Adleman (RSA) is that it provides equivalent security for a smaller key size, which reduces processing costs. From the theorical basic, we proposed a cryptosystem using elliptic curves and Vigenère cryptography. We proposed and implemented our encryption algorithm in an integrated development environment named visual studio 2019 to design a safe, secure, and effective cryptosystem.
