Cryptographic systems and protocols are the core of many Internet security procedures (such as SSL, SSH, IPSEC, DNSSEC, secure mail, etc.). At the heart of all cryptographic functions is a good source of randomness, and for efficiency, the primitive of PseudoRandom Generator (PRG). PRG can also be used in the design of stream ciphers, for secure communications. The Internet is nowadays composed of many types of devices with very different hardware and software characteristics. Hence, one of the concerns in such open environments is the information "Leakage" and its exploitation via the so-called "Side channel attacks".
