MARRERO TRAVIESO, Yran. La Criptografía como elemento de la seguridad informática. ACIMED [online]. 2003, vol.11, n.6, pp. 0-0. ISSN 1024-9435.

The arise of communication networks, particularly Internet, has paved the way for new chances in information interchange. There are also greater menaces to information security. In this case the creation of several mechanisms to guard the confidentiality and authenticity of electronic documents is necessary. All of this is part of a new technology called cryptography. Information security topics are discussed with emphasis in the cryptographic variants: symetrical and asymetrical. Some schemes for the management of public and private keys: RSA and PSP are exposed. Finally the limitations of some solutions offered by this new discipline are provided.
