Multilevel adaptive security system
… ad hoc networks. In this work, traditional data security mechanisms, existing ad hoc secure routing protocols and multilevel security are first reviewed. Then a new system, called the Multilevel Adaptive Security System, which incorporates the multilevel security concept at both the application …

Adaptive Security In Computer Networks
… system connected through them. If network security system could be dynamically reconfigured for new attacks, techniques and algorithms, computer networks would be able to provide better protection. The key challenge to achieve this adaptability is due to the lacking adaptive framework which …

Context Aware and Adaptive Security for Wireless Networks
… investigated methods to determine appropriate security protocols for specific wireless network applications. The specific problem being addressed was that there are tradeoffs between security, performance, and efficiency among current and proposed security protocols. Performance and efficiency …

Adaptive security in the threshold setting : from cryptosystems to signatures
Thesis (M.Eng. and S.B.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2001.

The paradigm of partial erasures
… is useful in many settings, including proactive security in the presence of a mobile adversary, adaptive security in the presence of an adaptive adversary, forward security, and intrusion resilience. Some of these settings, such as achieving proactive security, is provably impossible without some …

Flexible and Lightweight Cryptographic Engines for Constrained Systems
… all configurations of SIMON thus enables an adaptive security with variable key sizes. Our second proposed implementation is BitCryptor, a bit-serialized Compact Crypto Engine that can perform symmetric key encryption, hash computation and pseudo-random-number-generation. The implementation …

IMPROVING PERFORMANCE OF INTRUSION DETECTION SYSTEMS FOR SOFTWARE-DEFINED NETWORKS
… shift also exposes SDNs to a wide range of security threats, making them highly susceptible to sophisticated and dynamic cyberattacks. Traditional Intrusion Detection Systems (IDSs), often designed for static and monolithic network architectures, struggle to adapt to the dynamic nature and …

Web-based Secure Application Control
… applications. This thesis identifies the actual security requirements of modern web applications and shows that HTTP does not fit them: user and application authentication, message integrity and confidentiality, control-flow integrity, and application-to-application authorization. We explore the …

Two-Party and Threshold ECDSA constructions with bandwidth efficient instantiations from Class Groups of Imaginary Quadratic Fields
ECDSA è uno standard di firma digitale molto utilizzato nella pratica. Per quanto concerne le varianti distribuite di ECDSA, è difficile costruire soluzioni che non richiedano l'utilizzo di dimostrazioni a conoscenza zero costose necessarie a fronteggiare avversari malevoli. In questo manoscritto …

Context-Aware and Real-time Entrustment Framework for Securing Next Generation Internet Communications
… sensitive information worldwide. This insecurity is an inherent characteristic as the Internet did not make any security considerations in its initial design. Rather, as is famously known, it was designed to connect “mutually trusting users”. Such void motivated a long and extensive …
