1. Segurança do bit menos significativo no RSA e em curvas elípticas / Least significant bit security of the RSA and elliptic curves
Sistemas criptográficos como o RSA e o Diffie-Hellman sobre Curvas Elípticas (DHCE) têm fundamento em problemas computacionais considerados difíceis, por exemplo, o problema do logaritmo (PLD) e o problema da fatoração de inteiros (PFI). Diversos trabalhos têm relacionado a segurança desses sistemas com os problemas subjacentes. Também é investigad

2. Implementação e análise de desempenho dos protocolos de criptografia neural e Diffie-Hellman em sistemas RFID utilizando uma plataforma embarcada
RFID (Radio Frequency Identification) identifies object by using the radio frequency which is a non-contact automatic identification technique. This technology has shown its powerful practical value and potential in the field of manufacturing, retailing, logistics and hospital automation. Unfortunately, the key problem that impacts the application of RFID sy

3. DHA :um esquema de acordo de chaves baseado em matrizes para o protocolo Diffie-Hellman
In this work is proposed an annonimous cryptographic key agreement protocol by secure way based on Diffe-Hellman protocol. Actually key agreement protocols like Diffe-Hellman, ElGamal and other work with modular exponentiation operations and the complexity of such protocols are based on apparent diffcult to deal DLP (Discrete Logarithm Problems). The propose

4. SECURITY PROTOCOLS IN NETWORKS OF COMPUTERS / PROTOCOLOS DE SEGURANÇA EM REDES DE COMPUTADORES
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
