Which of the following security technologies’ strength is built upon being collision free?
A.
Hash
B.
Digital signatures
C.
Encryption
D.
Decryption
Explanation:
If a hashing algorithm creates the same message digest value for two
different messages, this is considered a collision. Collisions are used in birthday
attacks. Hashing algorithms with longer message digest values are less susceptible
to collisions and birthday attacks.
