Cryptography provides tools to ensure the confidentiality, authenticity, and integrity of information, the non-repudiation of actions or decisions, as well as the availability of services. While there is a wide range of protocols adaptable to a multitude of situations, all of them are susceptible to modification to suit the particular needs of a company or institution. We have patents for protocols for anonymous access control or remote electronic voting. Thus, we offer companies with specific needs the adaptation of our protocols to their requirements or, if necessary, the design of a specific protocol that meets their needs and guarantees the desirable properties mentioned above.
