Public key encryption using Hash digest
Not started
Public key cryptography combined with hash functions and digital signatures provides authentication, nonrepudiation, and integrity — features missing from simple public key encryption.
- Explain what is missing from simple public key encryption.
- Define hash function and message digest.
- Describe how digital signatures are created and verified.
- List the security dimensions this combined approach provides.
