Article: An encryption approach to improve the security and performance of data by integrating AES with a modified OTP technique Journal: International Journal of Advanced Intelligence Paradigms (IJAIP) 2024 Vol.27 No.2 pp.129 - 149 Abstract: Maintaining the security and privacy of data is of paramount priority while using the network and communication systems. Cryptography is an art used to solve the sole purpose of data security. Encryption serves as one of the most popular algorithms for cryptography. In this paper, a new encryption strategy is defined and implemented to enhance the security of data. The advanced encryption standard (AES) of 128-bit encryption has been used to protect the data, which can be moved up to 256-bit encryption if needed, along with a modified one-time pad (OTP) encryption technique. A newly devised method for random key generation named a secure key generator (SKG) is also proposed to add more security to the whole system. Hence, the paper carries a detailed study of the AES and OTP encryption techniques as well as compares the results of the modified OTP technique with existing encryption techniques.

Abstract: Maintaining the security and privacy of data is of paramount priority while using the network and communication systems. Cryptography is an art used to solve the sole purpose of data security. Encryption serves as one of the most popular algorithms for cryptography. In this paper, a new encryption strategy is defined and implemented to enhance the security of data. The advanced encryption standard (AES) of 128-bit encryption has been used to protect the data, which can be moved up to 256-bit encryption if needed, along with a modified one-time pad (OTP) encryption technique. A newly devised method for random key generation named a secure key generator (SKG) is also proposed to add more security to the whole system. Hence, the paper carries a detailed study of the AES and OTP encryption techniques as well as compares the results of the modified OTP technique with existing encryption techniques.
