gnupg: RSA secret key recovery via acoustic cryptanalysis

GnuPG 1.x before 1.4.16 generates RSA keys using sequences of introductions with certain patterns that introduce a side channel, which allows physically proximate attackers to extract RSA keys via a chosen-ciphertext attack and acoustic cryptanalysis during decryption. NOTE: applications are not...

CVE-2013-4576

GnuPG 1.x before 1.4.16 is vulnerable to a side-channel attack during RSA key handling. The issue arises from sequences of introductions with certain patterns that enable a local attacker to extract RSA keys via a chosen-ciphertext attack and acoustic cryptanalysis during decryption. The impact i...

CVE-2013-4576: Undefined Security Weakness

GnuPG 1.x before 1.4.16 generates RSA keys using sequences of introductions with certain patterns that introduce a side channel, which allows physically proximate attackers to extract RSA keys via a chosen-ciphertext attack and acoustic cryptanalysis during decryption. NOTE: applications are not...

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...

FreeBSD : gnupg -- RSA Key Extraction via Low-Bandwidth Acoustic Cryptanalysis attack (2e5715f8-67f7-11e3-9811-b499baab0cbe)

Werner Koch reports : CVE-2013-4576 has been assigned to this security bug. The paper describes two attacks. The first attack allows to distinguish keys: An attacker is able to notice which key is currently used for decryption. This is in general not a problem but may be used to reveal the...

Handling of Encryption, Tor Exposed in Leaked NSA Documents

New top-secret NSA documents released by the Guardian UK newspaper reveal that the United States’ top spy agency can retain encrypted communications for as long as it takes analysts to decrypt the secret messages—even if they’re collected by chance and without a warrant. In addition, the document...

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...

Large Scale Brute Force Cryptanalysis: Wisecracker

Large scale brute force cryptanalysis needs a tremendous amount of computational power that government agencies like the NSA and companies like Google® have. An average security researcher might want to have such capabilities as well but they do not have the tools or the computational resources...

Forthcoming SHA-3 Hash Function May Be Unnecessary

For the last five years, NIST, the government body charged with developing new standards for computer security, among other things, has been searching for a new hash function to replace the aging SHA-2 function. Fives years is a long time, but this is the federal government and things move at the...
