Correctness of Extended RSA Public Key Cryptosystem

This paper proposes an alternative approach to formally establishing the correctness of the RSA public key cryptosystem. The methodology presented herein deviates slightly from conventional proofs found in existing literature. Specifically, this study explores the conditions under which the choic...

Lattice-Based Cryptosystems and Quantum Cryptanalysis

Quantum computers are probably coming, though we dont know when--and when they arrive, they will, most likely, be able to break our standard public-key cryptography algorithms. In anticipation of this possibility, cryptographers have been working on quantum-resistant public-key algorithms. The...

Experts Uncover Passive Method to Extract Private RSA Keys from SSH Connections

A new study has demonstrated that it's possible for passive network attackers to obtain private RSA host keys from a vulnerable SSH server by observing when naturally occurring computational faults that occur while the connection is being established. The Secure Shell SSH protocol is a method for...

NIST Calls for Submissions to Secure Data Against Quantum Computing

For a layman, it may be difficult to fathom how a standards body could be playing catch-up to a threat that could be at least a decade away. But that’s the position NIST finds itself in with the risk that quantum computers pose to existing cryptographic algorithms. Working, practical quantum...

MD5 Message Digest Algorithm Hash Collision Weakness

No description provided by source. source: http://www.securityfocus.com/bid/11849/info The MD5 algorithm is reported prone to a hash collision weakness. This weakness reportedly allows attackers to create multiple, differing input sources that, when the MD5 algorithm is used, result in the same...

OpenSSL Heartbleed Highlights Crypto Pitfalls

There is no shortage of bad advice online about crypto–or anything else, for that matter. And the recent mess involving the OpenSSL heartbleed vulnerability has brought out plenty of advice on building, implementing and repairing cryptosystems, but experts say that the fundamental truths about ho...

Attack Exploits Weakness in RC4 Cipher to Decrypt User Sessions

It’s been more than 25 years since Ron Rivest invented his RC4 stream cipher, and after all that time it’s still being used widely, which is something of an achievement in the crypto world. However, for more than 15 years researchers have known about a weakness in RC4 that could enable an attacke...
