Workshop on Computational Security
In the current information society, security and integrity and crucial topics. Since the appearance of Information Theory with Claude E. Shannon at the end of the 40’s, secure transmission and correct reception of information were the most studied problems by the scientific community. The mathematical theories necessary to develop cryptography, coding theory and computer security provide tools used with two main purposes: protect the privacy of the information and guarantee its integrity when possible alterations may occur. The need of information security in public and private institutions has changed in the last years; it has grown from something exclusive of intelligence services to become something common that affects the whole society. Before the use of computers was so extended, information security was given by means of physical resources, for instance, the use of safes or classification of documents.
