The aim of this project is to contribute to the challenge of enforcing the confidence in the digital technologies, by finding new results, improvements and
advances in the design and study of the cryptographic primitives that, in a transversal/generic way, take part in the applications conforming a secure e-
Society. The results we aim to obtain, even being of mathematical/theoretical nature, must have an almost immediate impact in the improvement, in
terms of both security and efficiency, of some of the most common applications in the e-Society.
The research work proposed in this project includes (o contains) subjects like the design of improved cryptographic protocols for digital interactions,
including multiparty computation, encryption, digital signature, key exchange and generation and zero-knowledge proofs. These improvements are with
respect to the efficiency, the security or the extra features of the above mentioned protocols. The results will have an impact on the current e-voting
systems as well as on e-mail, e-commerce systems, private and secure authentication systems, secure cloud-storage and cloud-computing, anonymous
access control systems or confidential data sharing on social networks. The project also addresses the study and design of cryptographic primitives
extending distributed cryptography beyond the threshold barrier, to other access structures of practical interest. The criteria used here will be efficiency
and applicability to attribute based cryptography, e-voting, secure cloud-storage, access control systems and confidential data-sharing. We also aim to
analyze the security of existing cryptosystems that resist certain attacks based on quantum computers, and to propose new systems with this property.
Finally, another technical goal of this project is to improve the current knowledge of the relationships between the different computationally-hard
mathematical problems used in cryptography, and between the different security models. For instance, we plan to search for generic frameworks that
help simplifying the security analysis of cryptographic protocols. The theoretical character of this research does not prevent its practical implications,
because the mathematical problem on which the security of a protocol is based has direct consequences on the final complexity of the protocol, in
particular on efficiency parameters like the size of keys, ciphertexts or digital signatures.
Regarding its more informative and formative side, this project will have an impact on several sectors of the society (mainly companies and public
administration), which will be offered useful and clear information about the state-of-art in Cryptology, the guarantees it offers, and where and how it can
and must be used. We also stress the project impact on the future of research and applications of Cryptology, since the project will contribute to training
the next generation of cryptography experts, who will lead the future research in this area, either from research centers or from companies developing or
using secure digital solutions.
