Question

Quizplus · Accepted Answer

Triple DES (also known as 3DES) uses three keys in succession to encrypt a message, making it much more secure than DES which only uses one key. Triple DES was developed as an improvement to DES and is still widely used today in many applications. AES, Vernam, and Rijndael are all other encryption algorithms, but they do not directly relate to the development of Triple DES.
