Researchers Find Way to Extract 4096-Bit RSA Key via Sound

A trio of scientists have verified that results they first presented nearly 10 years ago are in fact valid, proving that they can extract a 4096-bit RSA key from a laptop using an acoustic side-channel attack that enables them to record the noise coming from the laptop during decryption, using a...

Cracking Cryptography and Encryption Exponentially Easier

It’s been a brutal month for crypto. Starting with the Black Hat conference, researchers, engineers and hackers have been unveiling new weaknesses and attacks in different cryptographic implementations that threaten the security of communication and commerce on the Web. Not only have holes been...

Matthew Green on Crypto Advances, the BREACH Attack and Whether the Longevity of the RSA Algorithm

Dennis Fisher talks with Matthew Green of Johns Hopkins University about the crypto advances in recent years, the BREACH attack revealed at Black Hat and whether it’s time to start moving away from the RSA algorithm.

Experts Urge ECC crytpo over RSA algorithm

LAS VEGAS – Cryptographic breakthroughs have accelerated in the past six months in areas such as discrete logarithm computations that lead experts to believe that breaking the stalwart RSA algorithm may be in the not-too-distant future. A team of crypto experts today at Black Hat USA 2013 present...

Cryptosystems Showing Signs of 'Wear and Tear'

SAN FRANCISCO– It’s been an interesting year in the cryptography world, with new attacks on several algorithms, continued problems with hash functions and the recent research on weak RSA keys. With all of that as a backdrop, some of the brightest minds in the field, gathered here for the RSA...

What You Need to Know About the RSA Key Research

It’s always slightly disorienting and confusing when a story about something as esoteric as weak encryption keys produced by poor random number generators makes its way into the real world and begins scaring the citizens. This can lead to confusion and worry about whether everyone’s online bankin...

Comodo hacker claim no relation to Iranian Cyber Army !

Comodo hacker claim no relation to Iranian Cyber Army ! The alleged hacker of Comodo stepped forward this weekend to explain how he generated bogus SSL certificates for login.skype.com, mail.google.com, login.live.com and other popular internet websites. His story is that he was able to compromis...

New Attack Against AES-256 a 'Huge Result'

A group of cryptographers has devised a new attack against AES, the de facto standard encryption algorithm, that enables them to recover an encryption key in far less time than had been possible before. The attack can recover an AES-256 key in a small enough amount of time to make the method...

OpenSSL本地密钥信息泄露漏洞

BUGTRAQ ID: 25163 CVECAN ID: CVE-2007-3108 OpenSSL是一种开放源码的SSL实现，用来实现网络通信的高强度加密，现在被广泛地用于各种网络应用程序中。 某些RSA的实现上存在可重建密钥的漏洞，OpenSSL基于SSLeay，提供RSA算法的加密支持，本地攻击者可能利用此漏洞通过RSA算法解密加密信息的内容。 多种使用了OpenSSL的产品可能受此漏洞影响。 OpenSSL Project OpenSSL 0.9.8e OpenSSL Project OpenSSL 0.9.8d OpenSSL Project OpenSSL 0.9.8c...

BUFFER OVERFLOW IN RSAREF2

Advisory ID Internal CORE-120199 Advisory ID: CORE-120199 CVE Name: CVE-1999-0834 Bugtraq ID: 843 While researching the exploitability of a buffer overflow in SSH up to version 1.2.27, we discovered a second buffer overflow in the implmementation of the RSA algorithm in RSAREF2 from RSA Data...
