Overall Integrity of Service Control in TINA Networks

1997
Conference Papers

Abstract

This article is concerned with protecting service control against interruption attacks. It investigates threats to service control in the Telecommunications Information Networking Architecture. Traditional security services protect message flows, but not service logic. Attackers can still interrupt service control connections and take advantage of the caused influences on service control, even if the messages are cryptographically protected. The focus of this article is to prevent this kind of attack. A protocol for protecting overall integrity of service control by means of a cryptographic protocol is presented and its use is demonstrated.

Cryptographic primitive

Cryptographic primitives are well-established, low-level cryptographic algorithms that are frequently used to build cryptographic protocols for computer security systems. These routines include, but are not limited to, one-way hash functions and encryption functions. When creating cryptographic systems, designers use cryptographic primitives as their most basic building blocks. Because of this, cryptographic primitives are designed to do one very specific task in a precisely defined and highly reliable fashion.

Key (cryptography)

A key in cryptography is a piece of information, usually a string of numbers or letters that are stored in a file, which, when processed through a cryptographic algorithm, can encode or decode cryptographic data. Based on the used method, the key can be different sizes and varieties, but in all cases, the strength of the encryption relies on the security of the key being maintained. A key's security strength is dependent on its algorithm, the size of the key, the generation of the key, and the process of key exchange.

Cryptographic protocol

A cryptographic protocol is an abstract or concrete protocol that performs a security-related function and applies cryptographic methods, often as sequences of cryptographic primitives. A protocol describes how the algorithms should be used and includes details about data structures and representations, at which point it can be used to implement multiple, interoperable versions of a program. Cryptographic protocols are widely used for secure application-level data transport.
