Abstract
In this study, the strength of data encryption algorithms used in UMTS and CDMA2000 systems which are 3G mobile communication technologies were analyzed. At the beginning of the study, software applications were developed for KASUMI encryption algorithm which is used within UMTS system and AES encryption algorithm which is used within CDMA2000 system. Both key generation algorithms are applied to the same key values to create new key values which are used for data encryption. These new key values are tested by using test package of NIST to in order to check whether these key values are generated randomly or not. One of the key value which has high randomness is used as encryption key As a result, it was observed that AES algorithm is more successful than KASUMI algorithm in generating key values. Additionally, a key value, which has high randomization, was chosen and this key value was applied on encryption algorithm with plain text statement and as a result application of en-crypted text on NIST test, it was observed that both KASUMI and AES block encryption algorithms have equally power in 3G mobile technology. * This paper is based on a Ph.D study titled “The Structure of Mobile Communication Technologies and Analysis of the Reliability of Data Encryption Algorithms Used in These Technologies”
