KASUMI - Wikipedia
KASUMI is a block cipher with 128-bit key and 64-bit input and output. The core of KASUMI is an eight-round Feistel network. The round functions in the main Feistel network are irreversible Feistel-like network transformations.
Kasumi - A5/3 - Cipher
The A5/3 encryption system – known as KASUMI - the Japanese word for "mist" - is the upgrade to A5/1 and uses a block cipher. A5/1 is designed to be used for the GSM network, whereas A5/3 is for 3GPP, and is based on the MISTY1 cipher created (and patented) by Mitsubishi, but was modified to reduce processing restrictions on mobile devices.
KASUMI is a block cipher that forms the heart of the 3GPP confidentiality algorithm f8, and the 3GPP integrity algorithm f9. This document is the second of four, which between them form the entire specification of the

A Detailed Overview of KASUMI-128 Encryption : Nim
KASUMI is a widely recognized block cipher used in mobile communications and data protection, ensuring secure transmission of sensitive information. In this page, you'll discover the fundamentals of KASUMI-128, its unique features, and why it's …
KASUMI is a block cipher which consists of eight Feistel rounds with a 128-bit key. Proposed more than 10 years ago, the confi-dentiality and integrity of 3G mobile communications systems depend on the security of KASUMI. In the practically interesting single key setting, only up to 6 rounds have been attacked so far.
Improved Cryptanalysis of the Block Cipher KASUMI
KASUMI is a block cipher which consists of eight Feistel rounds with a 128-bit key. Proposed more than 10 years ago, the confidentiality and integrity of 3G mobile communications systems depend on the security of KASUMI.
KASUMI (block cipher) - Academic Dictionaries and Encyclopedias
In cryptography, KASUMI, also termed A5/3, is a block cipher used in the confidentiality ("f8") and integrity algorithms ("f9") for 3GPP mobile communications. A number of serious weaknesses in the cipher have been identified.
KASUMI is a block cipher with eight Feistel rounds and a key of up to 128 bits. Proposed more than 10 years ago, the con dentiality and integrity of 3G mobile communications systems
It processes 64-bit blocks using 128-bit key. Basic core is very small (5,500 gates). Enhanced versions are available that support various cipher modes (ECB, CBC, OFB, CFB, CTR. The design is fully synchronous and available in both source and netlist form. Test bench includes the Kasumi test vectors.
