SECURING DATA USING HYBRID CRYPTOSYSTEM

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.
