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.
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 .
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).

RSA Laboratories stated: "Now that the industry has a considerably more advanced understanding of the cryptanalytic strength of common symmetric-key and public-key algorithms, these challenges are no longer active." [6] When the challenge ended in 2007, only RSA-576 and RSA-640 had been factored from the 2001 challenge numbers. [7]
The Solovay–Strassen primality test, developed by Robert M. Solovay and Volker Strassen in 1977, is a probabilistic primality test to determine if a number is composite or probably prime. The idea behind the test was discovered by M. M. Artjuhov in 1967 [ 1 ] (see Theorem E in the paper).

Parallel to that work in the information theory community is work in the antenna community, which has been termed near-field direct antenna modulation or directional modulation. [14] It has been shown that by using a parasitic array , the transmitted modulation in different directions could be controlled independently. [ 15 ]
