Blum Blum Shub on the GPU
Context. The cryptographically secure pseudo-random number generator Blum Blum Shub (BBS) is a simple algorithm with a strong security proof, however it requires very large numbers to be secure, which makes it computationally heavy. The Graphics Processing Unit (GPU) is a common vector processor originally dedicated to computer-game graphics, but has since been adapted to perform general-purpos...
متن کاملFast Blum-Blum-Shub Sequence Generation Using Montgomery Multiplication
VLSI modules are proposed for fast, efficient generation of high-throughput Blum-Blum-Shub (BBS) and BBS-like sequences using Montgomery Multiplication, where post-processing associated with Montgomery’s algorithm can be eliminated.
متن کاملNonquadratic Variation of the Blum-blum-shub Pseudorandom Number Generator
Cryptography is essential for secure online communications. Many different types of ciphers are implemented in modern-day cryptography, but they all have one common factor. All ciphers require a source of randomness, which makes them unpredictable. One such source of this randomness is a random number generator. This thesis focuses on Pseudorandom Number Generators (PRNG), specifically, a PRNG ...
متن کاملConcrete Security of the Blum-Blum-Shub Pseudorandom Generator
The asymptotic security of the Blum-Blum-Shub (BBS) pseudorandom generator has been studied by Alexi et al. and Vazirani and Vazirani, who proved independently that O(log log N) bits can be extracted on each iteration, where N is the modulus (a Blum integer). The concrete security of this generator has been analyzed previously by Fischlin and Schnorr and by Knuth. In this paper we continue to a...
متن کاملFaux anévrisme artériel traumatique intracrânien
Nous rapportons un cas d'anévrysme post-traumatique de l'artère carotide interne chez un enfant de 11 ans, ayant présenté une ophtalmoplégie droite. Un faux anévrisme de la carotide interne droite a été diagnostiqué par angiographie cérébrale. Le malade a bénéficié d'un traitement endovasculaire et l'évolution fut favorable. Malgré leur rareté, le diagnostic des anévrysmes post traumatiques dev...
