Question

Consider a variant of DSA in which the message space is Qantas omitted. (So the second component of the signature is now s:

A) The public key is absent.
B) The private key is absent.
C) The message space is modified.
D) The signature scheme is altered.

Answer 1

The question is about a variant of the DSA signature scheme where the message space is modified.

Step-by-step explanation:

The subject of this question is Computer Science and the grade level is College.

The question is asking about a variant of the DSA (Digital Signature Algorithm) signature scheme, in which the message space is modified. In this variant, the second component of the signature is changed to be s:A. This is different from the original DSA, where the second component is an integer between 1 and the order of the group.

This modification affects the way the signature is generated and verified, as it changes the mathematical operations involved. It is important to note that this variant is not the standard DSA and may have different security properties.
