It must be computationally infeasible to forge a digital signature,
either by constructing a new message for an existing digital
signature or by constructing a fraudulent digital signature for a given message.

Question

Quizplus · Accepted Answer

Digital signatures are designed to be secure in such a way that forging them—either by creating a new message to match an existing signature or by generating a fraudulent signature for a given message—is computationally infeasible, ensuring the integrity and authenticity of the signed data.
