Denial-of-provider (DoS) and distributed DoS (DDoS) are most of the principal threats to cyber-protection, and customer puzzle, which needs a client to carry out arithmetically highly-priced operations earlier than being allowed offerings from a server, is a good countermeasure to them. However, an attacker can inflate its capability of DoS assaults with speedy puzzle solving software and/or integrated Graphics processing unit (GPU) hardware to seriously weaken the effectiveness of Client puzzles. In this, we examine a path to save DoS attackers from inflating their puzzle-solving competencies. To this end, we introduce a new patron puzzle called software puzzle. Unlike the prevailing patron puzzle schemes, which publish their puzzle algorithms in advance, a puzzle set of rules in the current software puzzle scheme is randomly generated most effective after a client request is received at the server aspect and the algorithm is generated such that an attacker is unable to put together an implementation to resolve the puzzle earlier and the attacker needs enormous attempt in translating a Central processing unit puzzle software program to its functionally equivalent GPU version such that the interpretation cannot be achieved in actual time.
