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.
