- Blockchain: Design of privacy tools for blockchain scenarios.
Ph.D. research
My Ph.D. research focuses on new applications for MPC protocols in novel scenarios, e.g. blockchain. These protocols provide nice capabilities to enhance privacy in distributed environments, where different participants own different private data. MPC protocols require specific trade-offs between privacy and performance, which can condition their acceptance in different applications.

Thesis
- MSc. Thesis: Using Protocols for Secure Multiparty Computation on the Web:
The objective of this project is to carry out an analysis and a programming design of a primitive of the Secure Multiparty Computation paradigm for the web model. Specifically, the primitive Oblivious Transfer is studied, which forms the basis of several advanced cryptography protocols. For this purpose, the state of the art is analyzed, and the first specification of this primitive integrated in the Web Cryptography API is proposed, which enables cryptography at the application level in most of the web browsers. After specification, at the interface level, a prototype is presented, developed over the Node.js environment. - BSc. Thesis: Public Key infrastructure prototype using distributed RSA with secure multiparty computation:
Security has become a very important aspect in computer networking systems. Cryptography and the usage of trusted third parties have built the essential axis on which security is based for the most of Internet transactions. The objective of this work is to develop and analyze the viability of an RSA key pair management system to perform the generation and digital signature of public key certificates, using a secure protocol based on secure multiparty computation. To achieve that, the code needed to coordinate the key management servers has been designed. Those servers offer a distributed service, thanks to the coordination of an orchestrator, working at certification entity level. Code is offered in API REST format, because of its designing and integration convenience, and the facility to change things for an implementation of the proposed architecture on different systems.
