These days, the Web is used for software distribution and e-commerce. Virtual private networks (VPNs) are extending corporate networks to the Internet. Secure e-mail, Web access, e-commerce, VPNs and extranets require strong security that provides confidentiality, authentication, access control, data integrity and accountability.

There are a lot of different security technologies, protocols and algorithms developed for use in information security systems. Very often, these systems need random or pseudo-random numbers for their operation. For example, public key crypto-systems use keys that must be generated randomly. Many cryptographic protocols also require random or pseudo-random inputs at various points. Random numbers are used as auxiliary quantities when generating digital signatures or for generating challenges in authentication protocols.
