WebAug 31, 2024 · It is one of seven A5 ciphering algorithms which have been defined for GSM use. A5/3 (Kasumi) – KASUMI is a block cipher used in UMTS, GSM, and GPRS mobile communications systems. In UMTS, KASUMI is used in the confidentiality and integrity algorithms with names UEA1 and UIA1, respectively. A number of modes of operation have been designed to combine secrecy and authentication in a single cryptographic primitive. Examples of such modes are , integrity-aware cipher block chaining (IACBC) , integrity-aware parallelizable mode (IAPM), OCB, EAX, CWC, CCM, and GCM. Authenticated encryption modes are classified as single-pass modes or double-pass modes. Some single-pas…
