Descriptions

The TETRA TEA1 keystream generator implements a key register initialization function that compresses the 80-bit key to only 32 bits for usage during the keystream generation phase, which is insufficient to safeguard against exhaustive search attacks.

El generador de flujo de claves TETRA TEA1 implementa una función de inicialización de registro de claves que comprime la clave de 80 bits a solo 32 bits para su uso durante la fase de generación del flujo de claves, lo cual es insuficiente para protegerse contra ataques de búsqueda exhaustiva.
