Abstract
In any system, security is very crucial (algorithm). Security is a difficult aspect of network, system, and technological domains. It has now become a pre-requisite. After encapsulation, data delivered over the internet becomes more secure. For this aim, encryption is the most widely used and fundamental need for data security. Cryptography employs a variety of methods, including encrypting data at the sender's end and decrypting it at the receiver's end. There are two kinds of cryptography algorithms for safeguarding data: symmetric and asymmetric algorithms. Various symmetric and asymmetric algorithms, such as AES, DES, and triple DES, are examined in this study for their features and applications in mobile computing-based solutions.
