1WIRELESS NETWORKING CONCEPTSQuestion 1The three data encryption standards for the Worldwide Interoperability for MicrowaveAccess or WiMax are as follows:i) Advanced Encryption Standardii) Triple Data Encryption Standardiii) Rivest, Shamir and Adleman StandardThe proper comparison and contrast between the three above mentioned standards areas follows:Key FactorsAES3DESRSA1. DefinitionAES is the symmetricblock cipher, whichmakes utilization of aspecific 128 bits blocklength with the threelengths of key of 128bits, 192 bits and 256bits (Makimoto &Yamashita, 2013). 3DES is the symmetricblock cipher, whicheventually applies thealgorithm of dataencryption thrice in onedata block. The third encryptionstandard is RSAstandard. It wasdeveloped by the datasecurity of RSA. Thisalgorithm makesutilization of the primefactorization of twolarge numbers(Rappaport et al.,2015). 2. Size of KeyThe key sizes are 128bits, 192 bits and 256bits. The size of each key is56 bits. The key size is 2048bits and it is the mostpopular amongst therest. 3. Time forComputationAES is responsible forproviding the highestratio of speed forencryption, although,this speed decreaseswith the increasing sizein input file. The time forcomputation isminimum in thealgorithm of 3DES,although the differenceis negligible betweenAES and 3DES (Ho,Gao & Le-Ngoc, 2013).The highest timeconsuming method isthe RSA encryptionalgorithm and hence isoften avoided byvarious users. 4. Usage ofMemoryAES comprises of thelowest usage ofmemory. 3DES uses less memorythan RSA; however,higher memory thanAES. RSA algorithmconsumes the highestmemory. 5.AES has better3DES has betterRSA has lower
