To overcome this subject students will be able to: - Given a system with security requirements established to propose mechanisms and protocols required to provide some basic security services: authentication, authorization, privacy and access control. Give a measure of their effectiveness and limitations. - To design and evaluate appropriate measures for the identification and authentication of users and management of identities and associated authorizations.

PROGRAM This course covers the various aspects of data protection, especially focusing on the services of confidentiality, integrity and authenticity of information exchanged or stored. The course addresses these issues from a very practical standpoint, by conducting a case study over the development of consistent application of current data protection. The course syllabus is divided into four parts: * Part I: introduction.   - Presentation of the course: agenda, legislation, practical description of the case study.   - Introduction to the data protection: definitions, dimensions of information security.   - Types of encryption systems (symmetric / asymmetric) * Part II: symmetric encryption   - Block and stream ciphers.   - Encryption algorithms: DES, modes of operation, 2DES, 3DES, AES.   - Management of cryptographic keys. * Part III: asymmetric encryption   - RSA, Diffie-Hellman ECC. * Part IV: authentication and digital signature   - Authentication and one-way functions: cryptographic hash functions, Message Authentication Code (MAC).   - Digital Signature. Standards.   - Digital certificates and public key infrastructure (PKI) (digital certificates ITU-T X.509v3, trust Authorities (CA) and public key infrastructure (PKI), electronic signature legislation..

LEARNING ACTIVITIES Theoretical lectures Practical lectures Laboratory practices Tutoring sessions The teaching methodology will include: - Teacher exhibitions in classroom, with support of computer and audiovisual media, in which the main concepts of the subject are developed and the literature is provided to aid student learning. - Critical reading recommended by the teacher of texts related to the subject: newspaper articles, reports, manuals and / or academic articles, either for further discussion in class, either to expand and consolidate the knowledge of the subject. - Resolution of case studies, problems, etc. posed by the teacher individually or in groups. - Presentation and discussion in class under teacher moderation issues related to the content of matter, as well as case studies.
