RESUMO
This work analyses several algoritms of cryptography; among them, the DES (Data Encryption Standard), the public key algorithm RSA and the public key distribution algorithm DH of Diffie-Hellman. Three security protocols are then proposed for interactive and one-way communication in packet switched networks. The sirst protocol was proposed with the assumption that the algorthm of cryptography, used by the network is the DH, in conection with the DES to encipher the message. The third protocol considers the use of the RSA. The functions that shall be executed in each protocol are: communication with privacy, communication with authenticity, and signed communication. For the protocol DH/DES a model of cryptographical unit is proposed for the implementation of the functions wich will be executed by the protocol.
