Abstract:
Data security plays an important role in every organization. Therefore, many
organizations need to protect their information or data when data in transmission. This
system intends to implement the combination of the Advanced Encryption Standard
(AES) and Rivest-Shamir-leman (RSA) algorithm in order to more secure than single
algorithm. Pyay Education College to (PEC)’s Student marks file is sent from Pyay
Education College to Naypyidaw office for examination result. Student’s data are stored
in excel files format and placed in the computer. In this system, AES algorithm uses to
encrypt the student’s mark file, RSA algorithm uses to encrypt the AES’s key. Hash
based Message Authentication Code (HMAC) is applied to generate the hash value and to
authenticate transferred information between the two sides (that share a secret key).
Advantages of RSA algorithm and AES algorithm are combined in this system. The
proposed system is implemented using PHP programming language. The experimental
results show that hybrid AES-RSA cryptography system has been performed along with
data integrity.
