Pseudorandomness in cryptography
WebDec 20, 2012 · Abstract. This is a survey of pseudorandomness, the theory of efficiently generating objects that "look random" despite being constructed using little or no randomness. This theory has significance for a number of areas in computer science and mathematics, including computational complexity, algorithms, cryptography, … WebPseudorandomness is a crucial property that the designers of cryptographic primitives aim to achieve. It is also a key requirement in the calls for proposals of new primitives, as in the case of block ciphers. Therefore, the assessment of the property is an important issue to deal with. Currently, an interesting research line is the understanding of how powerful …

It is cryptographically secure if nobody can reliably distinguish the output from true randomness, even if the PRNG algorithm is perfectly known (but not its internal state).
WebMy research interests include cryptography, lattices, coding theory, algorithms, and computational complexity. A particular focus is on cryptographic schemes whose security can be based on the apparent intractability of latticeproblems. Further information may be found in my research summary.

In the book Introduction to modern cryptography by Katz and Lindell, I found this: Since the notion of choosing a function at random is less familiar than the notion of choosing a string at random, it is worth spending a bit more time on this idea.
In cryptography, the class usually consists of all circuits of size polynomial in the input and with a single bit output, and one is interested in designing pseudorandom generators that are computable by a polynomial-time algorithm and whose bias is negligible in the circuit size. These pseudorandom generators are sometimes called cryptographically secure pseudorandom generators (CSPRGs).
