Explanation

Substitution is a threat that occurs when an attacker replaces a valid digital signature with an invalid one, or a signature from another document. This can compromise the integrity and non- repudiation of the signed document, as the receiver cannot verify the authenticity and origin of the document. Substitution can be prevented by using secure hash algorithms and encryption to generate and protect the digital signatures.
