Security and Identification Indicators for Browsers against Spoofing and Phishing Attacks
Eprint
https://eprint.iacr.org/2004/155
Amir Herzberg Ahmad Gbara
In spite of the use of standard web security measures (SSL/TLS), users enter sensitive information such as passwords into scam web sites. Such scam sites cause substantial damages to individuals and corporations. In this work,...

Off-Path Hacking: The Illusion of Challenge-Response Authentication
Eprint
https://eprint.iacr.org/2013/623
Yossi Gilad Amir Herzberg Haya Shulman
Everyone is concerned about Internet security, yet most traffic is not cryptographically protected. Typical justification is that most attackers are off-path and cannot intercept traffic; hence, intuitively, challenge-response...

Detecting Mobile Application Spoofing Attacks by Leveraging User Visual Similarity Perception
Eprint
https://eprint.iacr.org/2015/709
Luka Malisa Kari Kostiainen Srdjan Capkun
Mobile application spoofing is an attack where a malicious mobile application mimics the visual appearance of another one. If such an attack is successful, the integrity of what the user sees as well as the confidentiality of...

Probabilistic and Considerate Attestation of IoT Devices against Roving Malware
Eprint
https://eprint.iacr.org/2017/1216
Xavier Carpent Norrathep Rattanavipanon Gene Tsudik
Remote Attestation (RA) is a popular means of detecting malware presence (or verifying its absence) on embedded and IoT devices. It is especially relevant to low-end devices that are incapable of protecting themselves against...

Provable Virus Detection: Using the Uncertainty Principle to Protect Against Malware
Eprint
https://eprint.iacr.org/2015/728
Richard J. Lipton Rafail Ostrovsky Vassilis Zikas
Protecting software from malware injection is the holy grail of modern computer security. Despite intensive efforts by the scientific and engineering community, the number of successful attacks continues to increase. We have...

Tamper-Evident Digital Signatures: Protecting Certification Authorities Against Malware
Eprint
https://eprint.iacr.org/2005/147
Jong Youl Choi Philippe Golle Markus Jakobsson
We introduce the notion of tamper-evidence for digital signature generation in order to defend against attacks aimed at covertly leaking secret information held by corrupted network nodes. This is achieved by letting observers...

Distributed Phishing Attacks
Eprint
https://eprint.iacr.org/2005/091
Markus Jakobsson Adam Young
We identify and describe a new type of phishing attack that circumvents what is probably today's most efficient defense mechanism in the war against phishing, namely the shutting down of sites run by the phisher. This attack...

Single Password Authentication
Eprint
https://eprint.iacr.org/2013/167
Tolga Acar Mira Belenkiy Alptekin Küpçü
Users frequently reuse their passwords when authenticating to various online services. Combined with the use of weak passwords or honeypot/phishing attacks, this brings high risks to the security of the user's account...

Committing Encryption and Publicly-Verifiable SignCryption
Eprint
https://eprint.iacr.org/2003/254
Yitchak Gertner Amir Herzberg
Encryption is often conceived as a committing process, in the sense that the ciphertext may serve as a commitment to the plaintext. But this does not follow from the standard definitions of secure encryption. We define and...

Towards Adoption of DNSSEC: Availability and Security Challenges
Eprint
https://eprint.iacr.org/2013/254
Amir Herzberg Haya Shulman
DNSSEC deployment is long overdue; however, it seems to be finally taking off. Recent cache poisoning attacks motivate protecting DNS, with strong cryptography, rather than with challenge-response ‘defenses’. Our goal is to...

PillarBox: Combating next-generation malware with fast forward-secure logging
Eprint
https://eprint.iacr.org/2013/625
Kevin D. Bowers Catherine Hart Ari Juels Nikos Triandopoulos
Security analytics is a catchall term for vulnerability assessment in large organizations capturing a new emerging approach to intrusion detection. It leverages a combination of automated and manual analysis of security logs...

Malware encryption schemes - rerandomizable ciphertexts encrypted using environmental keys
Eprint
https://eprint.iacr.org/2017/1007
Herman Galteland Kristian Gjøsteen
Protecting malware using encryption prevents an analyst, defending some computer(s) in the network, from analyzing the malicious code and identifying the intentions of the malware author. We discuss malware encryption schemes...
