1. Algoritmos de autenticação de mensagens para redes de sensores. / Message authentication algorithms for wireless sensor networks.
Security is an important concern in any modern network. However, networks that are highly dependent on constrained devices (such as sensors, tokens and smart cards) impose a difficult challenge: their reduced availability of memory, processing power and (specially) energy hinders the deployment of many modern cryptographic algorithms known to be secure. This

2. Cryptographic algorithms for sensor networks. / Algoritmos criptográficos para redes de sensores.
The need for security is a great concern in any modern network. However, networks that are highly dependent of constrained devices (such as sensors, tokens and smart cards) impose a difficult challenge: their reduced availability of memory, processing power and (more importantly) energy hinders the deployment of many important cryptographic algorithms known

3. CriptoanÃlise Diferencial
Since the creation of the standard of encryption of data DES (Data Encryption Standard) in 1978, iterative ciphers of based private key in nets of Feistel have been constructed, aiming at to increase the security of the information stored and transmitted in unsafe environments of communications. Such ciphers, besides in general presenting one high level of r
