Vulnerability Title
Intentionally weakened effective strength in TETRA TEA1
Source: CVE Program / CVE List V5
Vulnerability Description
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.
