| Abstract: | By use of the quantum algorithms of Shor,Boneh and Lipton,not only big integer factorization problems are solvable in polynomial time,but also discrete logarithm problems and discrete logarithm problems on elliptic curves can also be solved effectively by quantum comptuers.Thus the traditional Public-key Cryptosystem which is based on such three categories of intractable problems becomes no longer secure in the quantum computing epoch.So the new public-key cryptosystem,which is constructed on the basis of t... |
