intractability
41Numerical 3-dimensional matching — is a strongly NP complete decision problem. It is given by three multisets of integers X, Y and Z, each containing k elements, and a bound b. The goal is to select a subset M of such that every integer in X, Y and Z occurs exactly once and that… …

43Ensemble dominant — En théorie des graphes, un ensemble dominant d un graphe G = ( S, A ) est un sous ensemble D de l ensemble S des sommets tel que tout sommet qui n appartient pas à D possède au moins une arête commune avec un sommet de D. Le problème d ensemble… …
44Nombre domatique — En théorie des graphes, le nombre domatique d un graphe est son nombre maximum d ensembles dominants disjoints deux à deux. Le problème du nombre domatique est de déterminer, en fonction d un graphe G et d un entier naturel k, si le nombre… …

49Key size — In cryptography, key size or key length is the size measured in bits[1] of the key used in a cryptographic algorithm (such as a cipher). An algorithm s key length is distinct from its cryptographic security, which is a logarithmic measure of the… …
50Elliptic curve cryptography — (ECC) is an approach to public key cryptography based on the algebraic structure of elliptic curves over finite fields. The use of elliptic curves in cryptography was suggested independently by Neal Koblitz[1] and Victor S. Miller[2] in 1985.… …
