A New RSA Algorithm of Data Security by Large Numbers and Binary Stream Processing Methods

摘要

The RSA algorithm is extensively used in various fields of data security. However, the speed of its encryption/decryption operation is slow and requires improvement. In this study, we introduce an asymmetric cryptosystem to improve the Montgomery algorithm. The RSA algorithm is improved by annexing large numbers as a string and by employing binary stream processing methods. The key generation algorithm is used for encryption and decryption verification. Results show a significant improvement in encryption/decryption speed. The improved RSA algorithm used in digital signature applications results in an improved digital signature and offers evident advantages. The results have significant theoretical and practical significance in the efforts to improve large data processing encryption.
