SS7 is a signaling system for the public switched telephone network (PSTN) [1,2,3]. SS7 network transports call setup, teardown messages, database queries, trunk status, instructions for remote phone switches and so on, in fact it acts as a glue for the circuit switched networks. Before the deregulation act it was envisioned as a closed community network. After the deregulation, landscape has c...

The concept of using middleware-based architectures for telecommunication services in the broadband, multimedia, and information era is increasingly gaining acceptance. One representative example is the Telecommunications Information Networking Architecture (TINA), which is characterised by a variety of services, a multitude of service providers, a well-defined business model, a middleware plat...

As VoIP telecommunication networks are becoming popular, more and more VoIP calls are being madeto accomplish security critical activities, e.g., E911 services, phone banking. However, the security ram-ifications of using VoIP have not been fully recognized, and there exists a substantial gap in the under-standing of the potential impact of VoIP exploits on the VoIP users. In this c...

The MYSEA project has produced an innovative architecture and corrresponding engineering prototype consisting of trusted security services and integrated operating system mechanisms for the protection of distributed multi-domain computing environments from malicious code and other attacks. These security services and mechanisms extend and interoperate with existing workstations, applications an...

The Common Data Security Architecture (CDSA) is a general security service architecture which has been standardized by the Open Group. This paper compares the CDSA CAPI to another well known low-level CAPI, RSA’s PKCS #11 (Cryptoki). Both CDSA and Cryptoki are low-level interfaces which satisfy criteria established by the NSA’s CAPI Team. However, CDSA provides a security services infrastructur...
