Applications of computer security issues are limited to the operating systems and gadgets used within the computers and all other devices integrated with supercomputers. With the growing number of users, software developers face the software piracy which could affect the computer systems. Currently, the major problem for computers in the different industries is software piracy. Despite many computer security techniques, we have proposed a software watermark design based on return-oriented programming (ROP). Here, the new design of the software watermark is considered as a method in which secure Hash algorithm plays an important role to enhance the performance of the computer security. In this method, we focused on gadgets analysis gadgets categories and a large number of gadgets. In this analysis, we selected Sjeng benchmark and ROP with different approaches. As a theoretical result, resilience and stealthy are compared with existing results. This approach can be useful to improve the application of the computer security laws with legal procedures depended on the proposed computer security algorithms and analysis.

“…The BVR and KM15 schemes describe how pseudonyms can be introduced in the legacy networks. Also other proposals [3,9,10] were published in 2016 and 2017. All these proposals use essentially the same idea of using frequently changing pseudonyms recognized by the HN.…”

“…A potentially simple and backward compatible solution approach is to use frequently-changing temporary identities for mobile users [7,8,3,9,10]. The idea is that, if a UE communicates with an active IMSI catcher, it reveals only its temporary identity.…”

This paper is in the area of pseudonym-based enhancements of user identity privacy in mobile networks. Khan and Mitchell (2017) have found that in recently published pseudonym-based schemes an attacker can desynchronize the pseudonyms' state in the user equipment and in its home network. In this paper, we first show that by exploiting this vulnerability a botnet of mobile devices can kick out of service a large portion of the users of a mobile network. We characterize this novel DDoS attack analytically and confirm our analysis using a simulation. Second, we explain how to modify the pseudonym-based schemes in order to mitigate the DDoS attack. The proposed solution is simpler than that in Khan and Mitchell (2017). We also discuss aspects of pseudonym usage in mobile network from charging and regulatory point of view.

“…Another study investigated the IMSI encryption in which the IMSI-NC and CC data have defined and publicized the hidden identifier [15]. However, the routing requests for validation data between HN and visited network as well as the request for other IMSI data to be publicized within the HN are discussed here.…”

The fifth generation (5G) system is the forthcoming generation of the mobile communication system. It has numerous additional features and offers an extensively high data rate, more capacity, and low latency. However, these features and applications have many problems and issues in terms of security, which has become a great challenge in the telecommunication industry. This paper aimed to propose a solution to preserve the user identity privacy in the 5G system that can identify permanent identity by using Variable Mobile Subscriber Identity, which randomly changes and does not use the permanent identity between the user equipment and home network. Through this mechanism, the user identity privacy would be secured and hidden. Moreover, it improves the synchronization between mobile users and home networks. Additionally, its compliance with the Authentication and Key Agreement (AKA) structure was adopted in the previous generations. It can be deployed efficiently in the preceding generations because the current architecture imposes minimal modifications on the network parties without changes in the authentication vector's message size. Moreover, the addition of any hardware to the AKA carries minor adjustments on the network parties. In this paper, the ProVerif is used to verify the proposed scheme.
