Question

Digital signatures need a ________ ​

Answer 1

Answer:

Digital signatures are based on public key cryptography, also known as asymmetric cryptography. Using a public key algorithm, such as RSA (Rivest-Shamir-Adleman), two keys are generated, creating a mathematically linked pair of keys, one private and one public.

Answer 2

Digital signatures need a __asymmetric key system__ ​.

• The authenticity of a digital document can be verified through digital signatures.
• Asymmetric cryptography is employed in digital signatures.
• When a message or information is sent via a channel that is not secure then a digital signature serves as a means of security and validation.
• Digital signatures are mainly used for financial transactions, software distribution, and contract management software. It helps to detect tampering and forgery.
