The security of the LD scheme can be reduced to the one-wayness (aka preimage resistance) of the used hash function. The reduction is quite easy: Assume you want to invert the one-way function f for image y = f ( x), given a forger for LD-OTS. Then you generate a valid LD key pair using f, sample a random …

S/KEY is a one-time password system developed for authentication to Unix-like operating systems, especially from dumb terminals or untrusted public computers on which one does not want to type a long-term password. A user's real password is combined in an offline device with a short set of characters and a decrementing counter to form a single-use password. Because each password is only used once, they are useless to password sniffers.
