Efficient multivariate-based ring signature schemes
Demircioğlu, Murat; Cenk, Murat; Akleylek, Sedat; Department of Cryptography (2022-8-4)
The ring signature scheme has a wide range of usage areas in public-key cryptography. One is leaking information within a group without exposing the signer's identity. The majority of the ring signature techniques in use, on the other hand, rely on classical crypto-systems such as RSA and ECDH, which are known to be vulnerable to Shor's algorithm on a large-scale quantum computer. In this thesis, we propose efficient quantum-resistant ring signature schemes based on GeMSS and Gui signature algorithms. Gui w...
Multi-transducer ultrasonic communication
Ersagun, Erdem; Yılmaz, Ali Özgür; Department of Electrical and Electronics Engineering (2009)
RF and acoustic communications are widely used in terrestrial and underwater environments, respectively. This thesis examines the use of ultrasonic communication alternately in terrestrial applications. We first investigate the ultrasonic channel in order to observe whether reliable communication is possible among the ultrasonic nodes as an alternative to RF-based communications. Some key characteristics of the single-input-single-output (SISO) and single-inputmultiple- output (SIMO) ultrasonic channel are ...

A hybrid approach for full frame loss concealment of multiview video
Bilen, Çağdaş; Akar, Gözde; Department of Electrical and Electronics Engineering (2007)
Multiview video is one of the emerging research areas especially among the video coding community. Transmission of multiview video over an error prone network is possible with efficient compression of these videos. But along with the studies for efficiently compressing the multiview video, new error concealment and error protection methods are also necessary to overcome the problems due to erroneous channel conditions in practical applications. In packet switching networks, packet losses may lead to block l...
Çok Genişbantlı Mikrodalga Görüntüleme için Optimal MIMO Dizilimi
Kocamis, Burak; Öktem, Sevinç Figen (2017-05-18)
Wideband microwave imaging systems are recently used in various applications including airport security, surveillance, through-wall imaging and medicine. For the operation of such high-resolution systems, sparse multiple-input-multiple output (MIMO) arrays are of interest to reduce the hardware complexity and cost of conventional planar arrays. In this paper, we present a method for the optimal design of two-dimensional MIMO arrays in near-field imaging. Using a statistical framework, the optimality criteri...
