Now days several organizations started to build their security system during SDLC depending on an Outsourcing companies. The purpose of this study is to show how the outsourcer represented in Managed Security Service Provider (MSSP) can define and specify security requirements during software requirement engineering process. This paper introduced a new model that aims to define and specify security requirements during software requirement engineering using MSSP who can be considered as a new security member of the development team. Our new model added major security activities which should be performed via MSSP during software requirement engineering process. We analyzed our new model using CMMI and estimated it using COCOMO II-Early Design Model. We concluded that, using our new model will increase the security of customer's software system from the beginning of SDLC, and involving MSSP in the process will save security effort,Cost and Time.

Abstract Digital signature method is inspired from the handwriting signature, which must be unique and representative of an individual. The digital signature is a technique that allows identification of a user by relating one entity to one identity. Digital signature has many other applications in security field; including authentication, data integrity, and non-repudiation. The digital signature can be performed using asymmetric... Digital signature method is inspired from the handwriting signature, which must be unique and representative of an individual. The digital signature is a technique that allows identification of a user by relating one entity to one identity. Digital signature has many other applications in security field; including authentication, data integrity, and non-repudiation. The digital signature can be performed using asymmetric algorithm RSA, which is time-consuming. Hence, instead of ciphering all data, a representative data of the initial one is used. The minutiae point is an important feature of a fingerprint image due to the uniqueness characteristic of this descriptive set. The intent of this paper is to present an enhanced method for digital signature identification based one RSA and using minutiae point features of fingerprint image. Read More Read Less

Abstract We are interested in some applications of a new quantum algorithm in the case of quantum cryptography. We have analyzed in particular Grover algorithm and its implementation in the case of many qubits system. Some features of quantum cryptography are also presented and quantum cryptographic protocol, especially, Quantum Secret-Sharing protocol based on Grover’s algorithm is studied....

The IP Multimedia subsystem (IMS) is the technologies of convergence and interworking environment, with services flexibility, it‘s more than technical issue, it will prevail as core of Next Generation Network (NGN). The challenge and strategies of IMS architecture come from this convergence and the complexity of these technologies. In this work we present a novel design of architecture, that turns up some challenges of new IMS architecture and security system with optimal cost. The proposed architecture provides a robustness, reliability, scalability and strategy for extension in the future and responds to the security challenges. The architecture introduce clustering database HSS with automatic storage of data file that give a secure database. This paper respond to a most frank discussion about risk, investment and taking a security approach in IMS network issues, clearly we present the formula of the risk in IMS network and the comparison presented the impact of the cost signaling interworking with and without securing Gateway (SEG) with access network (AN) interworking between WiMAX and UMTS based on the new approach of secured architecture IMS. The result show the cost without Security Gateway (SEG), for signaling IMS traffic is lower than the cost with SEG, and the cost is increased by increasing arrival rate, there is a tradeoff between the level of increasing system security and the potential cost incurred .we conclude that this architecture is suitable for operators and services providers to protect against every conceivable threat, attacks , vulnerability and Denial of services.
