A digital signature is a mathematical scheme for verifying the authenticity of digital messages or documents. A valid digital signature, where the prerequisites are satisfied, gives a recipient very high confidence that the message was created by a known sender (authenticity), and that the message was not altered in transit (integrity). WebSome provide stronger cryptographic algorithms; others contain hardware components, such as smart cards. In addition, some CSPs can occasionally communicate directly with users, such as when digital signatures are performed by using the user's signature private key.

As with elliptic-curve cryptography in general, the bit size of the private key believed to be needed for ECDSA is about twice the size of the security level, in bits. For example, at a security level of 80 bits—meaning an attacker requires a maximum of about operations to find the private key—the size of an ECDSA private key would be 160 bits. ontario medical records onlineWebDec 10, 2012 · A (digital) signature is created with a private key, and verified with the corresponding public key of an asymmetric key-pair.
