Bellare - Random oracles are practical Random oracles are practical: A paradigm for designing efficient protocols Authors: M. Bellare and P. Rogaway Abstract: We argue that the random oracle model ---where all parties have access to a public random oracle--- provides a bridge between cryptographic theory and cryptographic practice. In the paradigm we suggest, a practical protocol P is produced by first devising and proving correct a protocol P^R for the random oracle model, and then replacing oracle accesses by the computation of an ``appropriately chosen'' function h. This paradigm yields protocols much more efficient than standard ones while retaining many of the advantages of provable security. We illustrate these gains for problems including encryption, signatures, and zero-knowledge proofs.

We also used this model in the design of incremental hash functions . Following our work, the random oracle model has been used in numerous other places. file:///C|/Documents%20and%20Settings/Linda%20Grauer/My. ..ents/Dolores/Berkeley-H2/CS276/2.07%20this%20paper.html [2/4/2008 11:46:16 AM]...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
