Magenta is the term for a symmetric algorithm for encryption , that of the Deutsche Telekom was developed between 1990 and 1998.
Magenta is a Feistel cipher with six rounds and was eliminated in the first round of the AES conference for the selection of a DES successor.
The name Magenta stands as an acronym for “Multifunctional Algorithm for General-purpose Encryption and Network Telecommunication Applications” (translated: multifunctional algorithm for general encryption and network communication applications). At the same time, the name is a tribute to the corporate design of Deutsche Telekom, which makes extensive use of the color magenta .
Cryptanalysis
The cryptologists Adi Shamir and Ross Anderson found theoretical attack possibilities during the 20-minute presentation of the algorithm. A short time later they proved that this attack is also practically possible and that the cryptosystem is therefore easy to break.
