APPARATUS AND METHOD FOR PERFORMING F8 CONFIDENTIALITY ALGORITHM AND F9 INTEGRITY ALGORITHM IN W-CDMA SYSTEM

摘要

An apparatus for performing encryption using a minimum encryption block in a mobile communication system, the apparatus comprising: an algorithm selector configured to selectively perform an encryption algorithm or an integrity algorithm on an input data; and an algorithm selected by the algorithm selector. And a control signal selector for correspondingly applying the corresponding encryption control signals to the kasumi unit, and a kasumi unit for kasumi operation on the input data using the applied control signal.;This means that the number of logic gates in the implementation of FPGA / ASIC is significantly increased by implementing the encryption algorithm (f8) and the integrity algorithm (f9) defined in 3GPP TS 35.201 v 3.1.1 in one UMTS system and UMTS terminal using one Kasumumi unit. Has the effect of reducing.;Kasumi, KASUMI, Encryption Algorithm, f8 Encryption Algorithm, f9 Integrity Algorithm, UMTS
