Rambutan Rambutan The rambutan (, taxonomic name: "Nephelium lappaceum") is a medium-sized tropical tree in the family Sapindaceae. The name also refers to the edible fruit produced by this tree. The rambutan is native to the Indonesian region, and other regions of tropical Southeast Asia. It is closely related to several other edible tropical fruits including the lychee, longan, and mamoncillo. The name "rambutan" is derived from the Malay word "rambut" meaning "hair", a reference to the numerous hairy protuberances of the fruit, together with the noun-building suffix "-an". Similarly, in Vietnam, it is called "chôm chôm" (meaning "messy hair"). Native
Rambutan (cryptography) output feedback operating modes (each in 64 bits) and the cipher feedback mode in 1 or 8 bits. Schneier suggests that these modes may indicate Rambutan is a block cipher rather than a stream. The three 64 bit modes operate at 88 megabits/second. Rambutan operates in three modes: ECB, CBC, and 8 bit CFB.
