A class of improved random number generators is termed cryptographically secure pseudorandom number generators, but even they require external to the software random seeds to work as intended.

There is some ambiguity to the term because some authors use the terms " Vernam cipher " and " one-time pad " synonymously, while others refer to any additive stream cipher as a " Vernam cipher ", including those based on a cryptographically secure pseudorandom number generator ( CSPRNG ).

The Yarrow algorithm is a cryptographically secure pseudorandom number generator.

ISAAC ( acronym for indirection, shift, accumulate, add, and count ) is a cryptographically secure pseudorandom number generator and a stream cipher designed by Robert J. Jenkins Jr. in 1996.

* An implementation of a cryptographically secure shrinking pseudorandom number generator.

* Alternating step generator, a cryptographically secure pseudorandom number generator

Specifically, Michael Luby and Charles Rackoff analyzed the Feistel cipher construction, and proved that if the round function is a cryptographically secure pseudorandom function, with K < sub > i </ sub > used as the seed, then 3 rounds is sufficient to make the block cipher a pseudorandom permutation, while 4 rounds is sufficient to make it a " strong " pseudorandom permutation ( which means that it remains pseudorandom even to an adversary who gets oracle access to its inverse permutation ).

If it is impractical to implement a true nonce, a strong cryptographically secure pseudorandom number generator and cryptographic hash function can generate challenges that are highly unlikely to occur more than once.

In 1991 Moni Naor showed how to create a bit-commitment scheme from a cryptographically secure pseudorandom number generator.

Hash functions can also be used in the generation of pseudorandom bits, or to derive new keys or passwords from a single, secure key or password.

Often this is done by first building a cryptographically secure pseudorandom number generator and then using its stream of random bytes as keystream.

This generator is not a cryptographically secure pseudorandom number generator for the same reason that the affine cipher is not secure.

The intent is to serve as a cryptographically secure pseudorandom number generator, delivering output with entropy as large as possible.

Subverted random numbers can be created using a cryptographically secure pseudorandom number generator with a seed value known to the attacker but concealed in the software.

Micali is best known for some of his fundamental early work on public-key cryptosystems, pseudorandom functions, digital signatures, oblivious transfer, secure multiparty computation, and is one of the co-inventors of zero-knowledge proofs.

Records of its use in later naval battles against the Saracens are more sporadic, but it did secure a number of victories, especially in the phase of Byzantine expansion in the late 9th and early 10th centuries.

It was impossible to prevent Charles from summoning a diet attended by a huge number of barons, and he was able to secure their support.

Clement X, seeing the results of the apostolic labours of the early French missionaries in Canada, the number of the faithful, and the wide field of labour, resolved to give the Church an independent organisation, and erected a see at Quebec, the bishop to depend directly on the Holy See ; this provision would later secure its permanence after Quebec passed into the hands of England.

More recent Unix or Unix like systems ( e. g., Linux or the various BSD systems ) use more secure password hashing algorithms such as PBKDF2, bcrypt and scrypt which have large salts and an adjustable cost or number of iterations.

Microsoft marketed Windows 2000 as the most secure Windows version ever at the time ; however, it became the target of a number of high-profile virus attacks such as Code Red and Nimda.

He declared in the Commons on 19 December that naval rearmament would commit the government to expenditure over a number of years and thus would subvert " the principle of annual account, annual proposition, annual approval by the House of Commons, which ... is the only way of maintaining regularity, and that regularity is the only talisman which will secure Parliamentary control ".

A cap-and-trade system constrains the aggregate emissions of regulated sources by creating a limited number of tradable emission allowances, which emission sources must secure and surrender in number equal to their emissions.

To address these shortcomings, a number of more secure variations of the bowline have been developed for use in safety-critical applications.

With the advent of IN, most of these services ( such as toll free numbers and geographical number portability ) were moved out of the core switch systems and into self serving nodes ( IN ), thus creating a modular and more secure network that allowed the services providers themselves to develop variations and value-added services to their network without submitting a request to the core switch manufacturer and wait for the long development process.

At the conclusion of the Democratic primary process that year, even with Jimmy Carter having the requisite number of delegates needed to secure his nomination, many still wanted Humphrey to announce his availability for a draft.

Clubbing with a number of like-minded friends to secure a large shared house with a manager was therefore a convenient solution.

A number of these were published in German in the main psychoanalytic periodicals published in Vienna and thereby served to secure his status in Freud's inner circle during the period of the latter's increasing estrangement from Jung.

As a result, a number of container-specific accessories have become available for a variety of applications, examples include ; Racking for archiving, Lining / Heating / Lighting / Powerpoints to create purpose-built secure offices, canteens and drying rooms, condensation control for furniture storage and ramps for storage of heavier objects.

NGSCB relies on hardware technology designed by members of the Trusted Computing Group ( TCG ), which provides a number of security-related features, including fast random number generation, a secure cryptographic co-processor, and the ability to hold cryptographic keys in a manner that should make them impossible to retrieve, even to the machine's owner.

After a troubled childhood and adolescence, during which he was expelled from a number of schools and eventually spent three months in prison for credit card fraud, he was able to secure a place at Queens ' College, Cambridge where he studied English Literature.

( In France, parties have to secure support from a specific number of elected officials, from a specific number of departments, in order to be eligible to run for election.

Although William's main rivals were gone, he still faced a number of rebellions over the following years, and it was not until after 1072 that he was secure on his throne.

Thirty seconds later, engineers detonated the mine charges laid under no man's land and the German trench line, destroying a number of German strong points and creating secure communication trenches directly across no man's land.
