  2. Illinois Standards Achievement Test - Wikipedia

    en.wikipedia.org/wiki/Illinois_Standards...

    Students were tested in science in grades 4 and 7. The writing portion of the test was suspended in 2011 due to lack of funding. The Illinois State Achievement Test reported out Lexile measures for students in grades 3–8. [2] A Lexile measure can be used to match readers with targeted text and monitor growth in reading ability.

  3. Prairie State Achievement Examination - Wikipedia

    en.wikipedia.org/wiki/Prairie_State_Achievement...

    The Prairie State Achievement Examination (PSAE) was a two-day standardized test taken by all high school Juniors in the U.S. state of Illinois. On the first day, students take the ACT, and on the second day, a WorkKeys examination and Illinois State Board of Education-developed science examination. [1]

  4. RSA (cryptosystem) - Wikipedia

    en.wikipedia.org/wiki/RSA_(cryptosystem)

    The RSA problem is defined as the task of taking e th roots modulo a composite n: recovering a value m such that c ≡ m e (mod n), where (n, e) is an RSA public key, and c is an RSA ciphertext. Currently the most promising approach to solving the RSA problem is to factor the modulus n .

  5. Information-theoretic security - Wikipedia

    en.wikipedia.org/wiki/Information-theoretic_security

    For example, RSA relies on the assertion that factoring large numbers is hard. A weaker notion of security, defined by Aaron D. Wyner , established a now-flourishing area of research that is known as physical layer encryption. [ 4 ]

  7. Dirichlet's approximation theorem - Wikipedia

    en.wikipedia.org/wiki/Dirichlet's_approximation...

    This theorem forms the basis for Wiener's attack, a polynomial-time exploit of the RSA cryptographic protocol that can occur for an injudicious choice of public and private keys (specifically, this attack succeeds if the prime factors of the public key n = pq satisfy p < q < 2p and the private key d is less than (1/3)n 1/4). [7]

  8. ChaCha20-Poly1305 - Wikipedia

    en.wikipedia.org/wiki/ChaCha20-Poly1305

    The two building blocks of the construction, the algorithms Poly1305 and ChaCha20, were both independently designed, in 2005 and 2008, by Daniel J. Bernstein. [2] [3]In March 2013, a proposal was made to the IETF TLS working group to include Salsa20, a winner of the eSTREAM competition [4] to replace the aging RC4-based ciphersuites.
