1. Comparison and Contrast of three data encryption standards for WiMAX
networks
At times of receiving and transmitting data with the help of WiMAX wireless
infrastructure, they do the uses of various encryption techniques like Advanced Encryption
Standard (AES) with 128-bit key, Rivest, Shamir and Adleman (RSA) with 1024-bit key and
Triple Digital Encryption Standard (3-DES). Regarding comparison, all AES, RSA are
considered as symmetric algorithm whereas 3-DES is considered as an asymmetric algorithm. In
addition to this, both AES as well as 3-DES uses two same keys for doing both the encryption
and decryption, whereas RSA uses two different keys for doing the encryption and decryption
(Sarkar, Basavaraju, & Puttamadappa, 2016). In all these encryption technique, both the
encryption and decryption techniques are Faster in AES, Moderate in DES and Slower in RSA
along with low power consumption in both AES and DES and higher in RSA. In addition to this,
both AES and DES use both different Deciphering and Ciphering algorithm whereas RSA does
both ciphering and deciphering using a same algorithm. Both the encryption and decryption time
also vary for all the AES, DES and RSA for an exact packet size. From the above comparison it
is deduced that the decryption of AES algorithm is better than the used decryption technique of
other algorithms (Lesavich & Lesavich, 2015). Regarding the contrast between AES, RSA and
DES highlights that for exchange of data using RSA it becomes needed to use other user public
key for encryption which can be decrypted with his/her private key only and the whole process
becomes time-consuming, whereas, in AES algorithm both can be done by using same key but
there is a high chance for data theft (Khedr, Abdalla, & Elsheikh, 2015). On other side, in DES,
