The bit-wise expressions are intended to hardware implementation but nowadays it is customary to use The substitution boxes (S-boxes) S7 and S9 are defined by both bit-wise AND-XOR expressions and look-up tables in the specification. The 128-bit key K is divided into eight 16-bit sub keys K i: In each round the round function uses a round keyĭerived from the original 128-bit key using a fixed key schedule. In the main Feistel network are irreversible Feistel-like network The core of KASUMI is an eight-round Feistel network. KASUMI is a block cipher with 128-bit key and 64-bit input and output. KASUMI algorithm is specified in a 3GPP technical specification. In January 2010, Orr Dunkelman, Nathan Keller and Adi Shamir released a paper showing that they could break Kasumi with a related-key attack and very modest computational resources this attack is ineffective against MISTY1. KASUMI is named after the original algorithm MISTY1 - 霞み (hiragana かすみ, romaji kasumi) is the Japanese word for 'mist'. Meet other requirements set for 3G mobile communications security. The original algorithm was slightly modified for easier hardware implementation and to They chose the cipher algorithm MISTY1 developed On an existing algorithm that had already undergone some evaluation.

īecause of schedule pressures in 3GPP standardization, instead of developing a new cipher, SAGE agreed withģGPP technical specification group (TSG) for system aspects of 3G security (SA3) to base the development (SAGE), a part of the European standards body ETSI.

KASUMI was designed for 3GPP to be used in UMTS security system by the Security Algorithms Group of Experts In GSM, KASUMI is used in the A5/3 key stream generator and in GPRS in the GEA3 key stream generator. In UMTS, KASUMI is used in the confidentiality ( f8) and integrity algorithms ( f9) with names UEA1 and UIA1, respectively. KASUMI is a block cipher used in UMTS, GSM, and GPRS mobile communications systems.
