Secure certificate sharing based on Blockchain framework for online education

In recent times, technology development has greatly influenced the model of Blockchain for communication due to extensive digitalization worldwide. Moreover, blockchain technology plays an essential part in the role of an educational system for sharing important data between students and teachers. However, the security hazard is the main problem while transferring the data because the malicious attacker may be able to hack the essential data in communication. A novel Signature-based Rivest Shamir Framework (SbRSF) is proposed to overcome such issues for privacy limit maintenance and security action improvement. Also, the harmful attack in data transmission is estimated by this projected approach. The implementation of this research has been done on the python platform. Hence, the proposed model has gained 98.03% throughput, encryption, and decryption time of 5 ms and reduced the error rate to 0.2%. Moreover, the achieved results are compared with the conventional methods, such as the Elliptic curve model, sensitivity-based elliptic crypto scheme, and secure record sharing, to validate the significance of the projected approach in blockchain development.
