“…The proposed method encrypts the data file before storing it in cloud storage and decrypts using One Time Password (OTP) during the retrieval process. Vishesh P. Gaikwad and et al (2020) had proposed a Chaotic hash function [16] to achieve user anonymity in Telecare Medicine Information System (TMIS). The proposed model incorporates Random Oracle (RO) model for providing security against cyber attacks.…”

The progression of digital technology impacts the users to migrate from traditional financial transactions to the online transaction system for performing their financial transactions. The existence of cloud computing and its major benefit of access from anywhere promotes financial transactions. The cloud infrastructure supporting performing financial transactions deals with the huge volume of data and it is quintessential to sustain a high level of security to those sensitive credentials in the cloud storage. The conventional cryptographic algorithms hold good in providing a better level of security to the sensitive data in cloud computing but still fall back to advanced attacks against the cloud data storage. Furthermore, the employment of conventional encryption algorithms in securing the cloud data consumes huge execution time, as it has to perform the authentication check for all types of user access including legitimate and non-legitimate accesses. This research article proposes a novel methodology of incorporating blockchain technology to perform online financial transactions in cloud computing with a high level of security, availability, and reduced execution time. This research work employs Blockchain technology integrated with Elliptical Curve Cryptography (ECC) and Chaotic Map Confusion and Diffusion algorithm to perform secured transactions over a cloud network. The interpretation of the proposed method contributes to better performance in the aforementioned parameters than the existing methodologies. The proposed framework is compared with the conventional method of online transactions using Multi-Factor Authentication (MFA) encompassing the Elliptical Curve Cryptography (ECC). The performance analysis proves that the proposed framework exhibits a high level of security along with reduced computational time, encryption, and decryption cost. The proposed work is interpreted with sample dataset and the computational time is reduced.

With the advancement of communication technology, Telecare Medicine Information Systems (TMIS) provides convenient healthcare services for patients, doctors, and health organizations over the insecure Internet. As a result, when accessing sensitive medical data over an insecure connection, user privacy, data security, and user authentication is very crucial. A secure authentication protocol plays a crucial role in securing communications over TMIS, these environments are very vulnerable to numerous attacks due to resource constraints and the nature of the communication medium. Recently, an efficient authentication framework has been introduced for TMIS to address various security issues. However, the existing mutual authentication and key agreement protocols are vulnerable to replay attacks, insider attacks, impersonation attacks, and password guessing attacks. Furthermore, the current authentication systems do not guarantee user privacy and the fair key agreement between the patient and the medical server. We propose a more robust authentication approach for healthcare information systems to address these security issues. To assess the authentication protocol's security strength, we employ formal verification tools like Automated Validation of Internet Security Protocols and Applications (AVISPA). Finally, a thorough performance analysis demonstrates that the proposed mutual authentication framework not only ensures privacy but also maintains a low computing overhead. As a result, when compared to other related systems, the proposed authentication protocol is both secure and computationally efficient.
