# Safeguarding cryptographic keys

@article{Blakley1979SafeguardingCK, title={Safeguarding cryptographic keys}, author={G. R. Blakley}, journal={1979 International Workshop on Managing Requirements Knowledge (MARK)}, year={1979}, pages={313-318} }

Certain cryptographic keys, such as a number which makes it possible to compute the secret decoding exponent in an RSA public key cryptosystem,1,5 or the system master key and certain other keys in a DES cryptosystem,3 are so important that they present a dilemma. [... ] Key Result The answer is that there are at least three types of incidents: Expand

Protecting Shared Cryptographic Keys

- Computer Science, Mathematics1980 IEEE Symposium on Security and Privacy
- 1980

A scheme for distributing a key to n users in such a way as to require at least k of them to be present to construct the original key has the property that up to k - 1 defections can be tolerated.

Threshold Cryptosystems

- Computer ScienceCRYPTO
- 1989

Practical non-interactive public key systems are proposed which allow the reuse of the shared secret key since the key is not revealed either to insiders or to outsiders.

This paper Shamir threshold scheme based on the protection of private keys, by constructing a Lagrange interpolating polynomial to achieve in the real environment using the key shared information…

Simulatability and Security of Certificateless Threshold Signatures without Random Oracles

- Computer Science, Mathematics2008 International Conference on Computational Intelligence and Security
- 2008

This is the first construction of certificateless threshold signature scheme that does not rely on random oracle or ideal ciphers and is proven secure against the malicious-but-passive KGC attack.

A Forward-Secure Digital Signature Scheme

- Computer Science, MathematicsCRYPTO
- 1999

We describe a digital signature scheme in which the public key is fixed but the secret signing key is updated at regular intervals so as to provide a forward security property: compromise of the…

Threshold Key-Recovery Systems for RSA

- Computer ScienceSecurity Protocols Workshop
- 1997

Although threshold key-recovery systems for the discrete log based cryptosystems such as the ElGamal scheme have been proposed by Feldman and Pedersen [6, 11, 12], no (practical) threshold…

How Exhausting is Exhaustive Search

- Computer Science
- 1997

It is unknown whether any such machine has been built, and DES is still very widely used, in part because of its continued resistance to sophisticated cryptanalytic attacks.

A Proactive Secret Sharing Scheme Based on Elliptic Curve Cryptography

- Computer Science, Mathematics2009 First International Workshop on Education Technology and Computer Science
- 2009

This article presents a proactive verifiable secret sharing scheme based on Elliptic Curve Cryptosystem, which is secure and effective.

Probabilistic secret sharing scheme for binary images

- Computer Science2015 Communication, Control and Intelligent Systems (CCIS)
- 2015

A probabilistic (2, n) SS scheme based on XOR operation is proposed for binary images and shows that the scheme has satisfactory contrast, less prone to security attacks along with reasonable computation time.

Veri able Secret SharingMarkus Stadler ? Institute for Theoretical Computer ScienceETH

- Computer Science, Mathematics

Publicly veriiable secret sharing schemes are called, new applications to escrow cryptosystems and to payment systems with revocable anonymity are discussed, and two new realizations based on ElGamal's cryptos system are presented.
