بدون تردید، اینترنت باعث وقوع انقلاب فراگیر در کل سیستم ارتباطی دنیا شده است. به جرات می توان گفت که جهان هیچگاه شاهد چنین شتابی برای استفاده از یک پدیده علمی نبوده است. امروزه تصور زندگی بدون بسیاری از خدمات مبتنی بر اینترنت امکان پذیر نمی باشد. یکی از تهدیدات بزرگ برای ارائه خدمات ،حملات انکار سرویس توزیع شده می باشد.با وجود تحقیقات بسیار بر روی این موضوع، هنوز هم این حملات به عنوان یکی از بز...

IMS (IP Multimedia Subsystem) network is considered as an NGN (Next Generation Network) core networks by ETSI. Decomposition of IMS core network has resulted in a rapid increase of control and signaling message that makes security a required capability for IMS commercialization. The control messages are transmitted using SIP (Session Initiation Protocol) which is an application layer protocol. ...

علی‌رغم آنکه استفاده از خدمات سرورهای برونسپاری شده جریان داده مورد اقبال زیادی قرار گرفته ولی هنوز مساله کسب اطمینان از جامعیت نتایج دریافتی از این سرورها یکی از چالش‌های اساسی سازمانها است. برای برونسپاری این خدمات، کاربر باید از عملکرد درست و امانت‌دارانه سرور و کانال ارتباطی مطمئن شود چرا که سرور ممکن است به دلایل اقتصادی و یا بدخواهانه جامعیت نتایج را مورد حمله قرار دهد. در این حملات بخشی ...

The extent and diversity of systems provided by IP networks have made various technologies to approach integrating various types of access networks and converting to next generation network. The Session Initiation Protocol (SIP) with respect to facilities such as being in text form, end-to-end connection, independence from the type of transmitted data, and supporting various forms of transmissi...

This article provides a comparison of two of the most promising technologies which are supposed to be used for enabling communications over the Internet: IMS and P2PSIP. As their fields of adoptions are totally different – operators and mobile networks for the former, Internet and ephemeral communities for the latter – interoperability rather than competition seems to be the key for achieving a...

The mechanisms which enable the vast majority of computer attacks are based on design and programming errors in networked applications. The growing use of voice over IP (VOIP) phone technology makes these phone applications potential targets. We present a tool to perform security testing of VOIP applications to identify security vulnerabilities which can be exploited by an attacker. Session Ini...
