निजी-कुँजी इसके अंग्रेजी अर्थ का उदाहरण

The current proposals use perturbations to increase the transcript length required to recover the private key: the signer displaces the point representing the message by a small secret amount before the signature itself is calculated.

Otherwise, each additional signature reusing the private key reduces the security level against adversaries that might later create false signatures from them.

In a regular signcryption scheme, when the long-term private key is compromised, all the previously issued signatures will not be trustworthy any more.

We assume Bob knows his own private key x.

However, analysis had shown that original scheme is insecure and would leak knowledge of private key.

It was demonstrated in 2000 by Wu, Bao, Ye and Deng that the signature of PASS, the original version of NTRUSign, can be forged easily without knowing the private key.

Lyons (state) Elliptic-curve Diffie–Hellman (ECDH) is a key agreement protocol that allows two parties, each having an elliptic-curve public–private key pair, to establish a shared secret over an insecure channel.

Private static key agreement key: Private static key agreement keys are the private keys of asymmetric key pairs that are used to establish keys (e.

Then n is the public key and the pair (p,q) is the private key.

NTRUSign is not a zero-knowledge signature scheme and a transcript of signatures leaks information about the private key, as first observed by Gentry and Szydlo.

Based on Grover's algorithm, a quantum secure system, the length of the public key elements zi,j, the private key elements yi,j and the signature elements si,j must be no less than 2 times larger than the security rating of the system.

Winternitz signature compression reduces the size of the private key and public key by slightly less than a factor of the 2\langle\text{chunk size in bits}\rangle, and half that factor for the signature.

:* Confidentiality: It should be computationally infeasible for an adaptive attacker to gain any partial information on the contents of a signcrypted text, without knowledge of the sender's or designated recipient's private key.
