Descriptions
The TETRA TA61 identity encryption function internally uses a 64-bit value derived exclusively from the SCK (Class 2 networks) or CCK (Class 3 networks). The structure of TA61 allows for efficient recovery of this 64-bit value, allowing an adversary to encrypt or decrypt arbitrary identities given only three known encrypted/unencrypted identity pairs.
La función de cifrado de identidad TETRA TA61 utiliza internamente un valor de 64 bits derivado exclusivamente de SCK (redes Clase 2) o CCK (redes Clase 3). La estructura de TA61 permite una recuperación eficiente de este valor de 64 bits, lo que permite a un adversario cifrar o descifrar identidades arbitrarias con solo tres pares de identidades cifradas/no cifradas conocidas.
