BIAS: Bluetooth Impersonation AttackS
Bluetooth (BR/EDR) is a pervasive technology for wireless communication used by billions of devices. The Bluetooth standard includes a legacy authentication procedure and a secure authentication procedure, allowing devices to authenticate to each other usi ...
IEEE COMPUTER SOC2020Provably Secure Authenticated Encryption
Authenticated Encryption (AE) is a symmetric key cryptographic primitive that ensures confidentiality and authenticity of processed messages at the same time. The research
of AE as a primitive in its own right started in 2000.
The security goals of AE wer ...
EPFL2018Can Caesar Beat Galois?
The Competition for Authenticated Encryption: Security, Applicability and Robustness (CAESAR) has as its official goal to “identify a portfolio of authenticated ciphers that offer advantages over [the Galois-Counter Mode with AES]” and are suitable for wid ...
2018Linking Online Misuse-Resistant Authenticated Encryption and Blockwise Attack Models
Real-world applications of authenticated encryption often require the encryption to be computable online, e.g. to compute the ith block of ciphertext after having processed the first i blocks of plaintext. A significant line of research was dedicated to id ...
2017Keystroke Biometrics Ongoing Competition
This paper presents the first Keystroke Biometrics Ongoing Competition (KBOC) organized to establish a reproducible baseline in person authentication using keystroke biometrics. The competition has been developed using the BEAT platform and includes one of ...
2016Online Authenticated-Encryption and its Nonce-Reuse Misuse-Resistance
Damian Vizár, Reza Reyhanitabar
A definition of online authenticated-encryption (OAE), call it OAE1, was given by Fleischmann, Forler, and Lucks (2012). It has become a popular definitional target because, despite allowing encryption to be online, security is supposed to be maintained ev ...
Springer2015The Limits of Composable Crypto with Transferable Setup Devices
UC security realized with setup devices imposes that single instances of these setups are used. In most cases, UC-realization relies further on other properties of the setups devices, like tamper-resistance. But what happens in stronger versions of the UC ...
ACM2015Deterministically Deterring Timing Attacks in Deterland
The massive parallelism and resource sharing embodying today’s cloud business model not only exacerbate the security challenge of timing channels, but also undermine the viability of defenses based on resource partitioning. We propose hypervisor-enforced t ...
Association for Computing Machinery2015Face liveness detection using dynamic texture
Sébastien Marcel, André Anjos, Tiago De Freitas Pereira
User authentication is an important step to protect information, and in this context, face biometrics is potentially advantageous. Face biometrics is natural, intuitive, easy to use, and less human-invasive. Unfortunately, recent work has revealed that fac ...
