Post-Quantum Verifiable Oblivious Pseudorandom Functions
This work presents the construction of a post-quantum verifiable oblivious pseudorandom function (VOPRF) with a focus on efficiency and practicality. Leveraging lattice-based cryptographic primitives, particularly the Learning With Errors (LWE) problem, our VOPRF construction aims to address the …

Signature schemes and applications to cryptographic protocol design
… and as a building block in the design of secure protocols and other cryptographic objects. In this thesis, we study both the uses that signature schemes find in protocols, and the design of signature schemes suitable for a broad range of applications. An important application of digital …

Proof-carrying data
The security of systems can often be expressed as ensuring that some property is maintained at every step of a distributed computation conducted by untrusted parties. Special cases include integrity of programs running on untrusted platforms, various forms of confidentiality and side-channel …

Succinct non-Interactive arguments
… arguments (SNARGs), also known as "CS proofs" [Micali, FOCS 1994], enable verifying NP statements with much lower complexity than required for classical NP verification (in fact, with complexity that is independent of the NP language at hand). In particular, SNARGs provide strong …

Location Privacy in VANETs: Improved Chaff-Based CMIX and Privacy-Preserving End-to-End Communication
… journey circumstances, and in the provision of infotainment that considerably enhance transportation safety and quality. The entities in VANETs, generally vehicles, form part of a massive network known as the Internet of Vehicles (IoV). The deployment of large-scale VANETs systems is …

Autentizované ustanovení klíče s podporou sdíleného tajemství
Práce se zabývá implementací a vytvořením kryptografické knihovny a grafického uživatelského rozhraní (GUI) pro nově navržený protokol "Smlouva o autentizačním klíči na základě Shamirova sdílení tajemnství" (ang. "Shamir’s Secret Sharing-based Authenticated Key Agreement", zkráceně ShSSAKA). …
