Security Through Digital Signatures Paper Presentation And Power Point

Digital signatures are an analog of handwritten signatures. Handwritten signatures are based on the physically idiosyncratic way of signing one's name. But they can be easily forged. A digital signature is a mathematically precise way of attaching one's identity to a message. It is much harder to forge than a handwritten signature, and the signed message cannot be altered without also invalidating the signature. A digital signature provides verification to a recipient that a signed file is actually sent by the sender, and is not altered after it is signed.Digital signatures rely on public key cryptography. Public key cryptography is an asymmetric scheme that uses a pair of keys for encryption: a public key, which encrypts data, and a corresponding private, or secret key for decryption. You publish your public key to the world while keeping your private key secret. Anyone with a copy of your public key can then encrypt information that only you can read. Even people you have never met.
