The digital signature is a method to save the news which is signed with electronic form.Those news can be delivered through Internet. Though a lot of digital signature projects are put forward currently,however many schemes lack the certification on safety and exist various problem afterwards.This paper introduces a digital signature scheme which can be proved to be safe. It is full field Hash signature scheme under the random oracle model. Under the circumstance that we know key and acquire the random oracle model,we analyze the possibility of counterfeiting signature.This paper puts forward a perfect FDH-Invert algorithm,the ability of calculating reverse depends on using little Hash search to find out FDH-Forge algorithm which can counterfeit signature.
