What is Digital Signature? cyber security terminology#education #vlrtraining #cybersecurity
A digital signature is a cryptographic technique used to authenticate the identity of the sender of a digital message and to ensure that the message has not been altered. It's like a digital fingerprint that verifies the authenticity and integrity of a document or message.
Here's how it works:
Hashing: The message is converted into a unique hash value.
Encryption: The sender encrypts the hash value using their private key.
Attachment: The encrypted hash value (digital signature) is attached to the message.
When the recipient receives the message and signature, they can verify its authenticity by:
Decryption: Decrypting the signature using the sender's public key.
Hashing: Hashing the received message.
Comparison: Comparing the decrypted hash with the newly calculated hash.
If the two hashes match, the message is verified as authentic and unaltered.
