Descriptions

The Motorola MDLC protocol through 2022-05-02 mishandles message integrity. It supports three security modes: Plain, Legacy Encryption, and New Encryption. In Legacy Encryption mode, traffic is encrypted via the Tiny Encryption Algorithm (TEA) block-cipher in ECB mode. This mode of operation does not offer message integrity and offers reduced confidentiality above the block level, as demonstrated by an ECB Penguin attack against any block ciphers.

El protocolo MDLC de Motorola versiones hasta 02-05-2022, maneja inapropiadamente la integridad de los mensajes. Soporta tres modos de seguridad: Simple, Encriptación Legada y Nueva Encriptación. En el modo Legacy Encryption, el tráfico es cifrado por medio del cifrado en bloque Tiny Encryption Algorithm (TEA) en modo ECB. Este modo de funcionamiento no ofrece la integridad de los mensajes y ofrece una confidencialidad reducida por encima del nivel de bloque, como demuestra un ataque ECB Penguin contra cualquier cifrado de bloque.
