In today’s digital era, secure data transmission between a data owner and users is critical. This paper presents a novel framework that combines One-Time Password (OTP) generation with an RSA-based key exchange mechanism to ensure robust data protection. Each time the data owner initiates data sharing; a unique OTP is dynamically generated and encrypted using the RSA algorithm. This OTP acts as a secure access key, ensuring that only authorized users can decrypt and retrieve the shared information. The RSA encryption not only secures the OTP but also establishes a secure communication channel between the data owner and the user, preventing unauthorized access or interception during transmission. By integrating dynamic OTPs with asymmetric encryption, this scheme enhances the confidentiality and integrity of data in environments where security.
