Adversarial Models Attacks - standard model: Chosen-plaintext attacks Chosen-ciphertext attacks Composition/A function f:{0,1} n → {0,1} n is called a (t,ε) one-way function, if f is a polynomial-time computable function (independent of t) for every t-time algorithm A, Prob[A(f(x))  f -1 (f(x)) ] ≤ ε Where /


CHAPTER 5: Public-key cryptography

Informally, a function F:N -> N is said to be one-way function if it is easily computable - in polynomial time - but any computation of its inverse is infeasible. A one-way permutation is a 1-1 one-way function. easy x f(x) computation/seems to be infeasible. Example If A = (74, 82,94, 83, 39, 99, 56, 49, 73, 99) and B = (1100110101) then ABT = Public-key cryptography Another view of the knapsack problem IV054 Another view of the knapsack problem Each knapsack vector A = (a1,…,an) defines an integer valued /

We introduce infinite dimensional algebra (purely abstract device) (fg)h=f(gh) Algebra of formal power series deg f: Scalar polynomial cx 0 Monic polynomial f n = 1. Theorem 1: f, g nonzero polynomials over F. Then 1.fg is nonzero. 2.deg(fg)=deg f + deg/. This is the Lagrange interpolation formula. –This follows from Theorem 15. P.99.
