Asynchronous Provably-Secure Hidden Services [chapter]

Philippe Camacho, Fernando Krell
2018 Lecture Notes in Computer Science  
To the best of our knowledge this is the first study of asynchronous protocols that provide strong security guarantees for the hidden server problem.  ...  Nonetheless our solution has two major advantages: it is asynchronous and it is secure against any number of corrupted nodes.  ...  Tor hidden services [8] is without a doubt the most popular alternative for this purpose.  ...

Virtual Hidden Network [chapter]

Natori Shin
2001 IFIP Advances in Information and Communication Technology  
In this paper, we first propose a new type of network model named Virtual Hidden Network (VHN), an invisible network layered over steganography channels.  ...  If a steganography system is secure enough, no eavesdropper can detect the existence of hidden message.  ...  The security of a steganography system is the difficulty for the eavesdroppers to detect the existence of hidden message.  ...

DISTRIBUTED DENIAL OF SERVICES ATTACKS AND THEIR PREVENTION IN CLOUD SERVICES

SARAH NAIEM, MOHAMED MARIE, AYMAN E. KHEDR, AMIRA M. IDREES
2022 Zenodo  
Distributed Denial of services (DDOS) attacks are one of the most famous attacks that affect the availability of a service making it a serious problem especially when it comes to cloud computing as it  ...  The prevention of the DDOS attacks is the foremost important step in protecting the cloud from DDOS which is achieved through challengeresponse, hidden servers, and restrictive access approaches.  ...  While the Hidden server helps legit clients to access the services provided without any direct connection with the server at the beginning but it requires an extra layer of security for redirection and  ...

Game of Threads

Jose Rodrigo Sanchez Vicarte, Benjamin Schreiber, Riccardo Paccagnella, Christopher W. Fletcher
2020 Proceedings of the Twenty-Fifth International Conference on Architectural Support for Programming Languages and Operating Systems  
This paper studies the security implications of these codes by introducing asynchronous poisoning attacks.  ...  In asynchronous training, many threads share and update model parameters in a racy fashion to avoid costly interthread synchronization.  ...  We explore the implications of asynchronous training on machine learning model integrity, in adversarial settings. Consider a setting such as Machine Learning as a Service (MLaaS) [1, 2] .  ...

Cryptanalysis of GlobalPlatform Secure Channel Protocols [chapter]

Mohamed Sabt, Jacques Traoré
2016 Lecture Notes in Computer Science  
Second, we investigate the security of SCP03 that was introduced as an amendment in 2009. We find that it provably satisfies strong notions of security.  ...  Our findings highlight the great value of the paradigm of provable security for standards and certification, since unlike extensive evaluation, it formally guarantees the absence of security flaws.  ...  Our goal is thus to study them through provable security, and hence to validate (or invalidate) the security guaranteed by GP.  ...
