Cryptographic Protection of Connection Integrity with Interruption Detection in TINA

1997
Conference Papers

Abstract

The Telecommunications Information Networking Architecture (TINA) provides the architectural basis for the realization of telecommunications services as distributed applications. In particular application of distributed systems, new security problems arise. We discuss threats that are caused by the interruption of service control connections. A method to detect interruptions is presented and the handling of interruptions is described. The detection method is based on a cryptographic protocol using sequence numbers and probe messages. TINA and its security approaches are introduced. The threats by interruption are illustrated using a toll fraud example. Keywords: TINA, Connection Integrity, Security States, Sequence Numbers, Probe Messages

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.

Cryptography

Cryptography, or cryptology (from κρυπτός "hidden, secret"; and γράφειν graphein, "to write", or -λογία -logia, "study", respectively), is the practice and study of techniques for secure communication in the presence of adversarial behavior. More generally, cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages. Modern cryptography exists at the intersection of the disciplines of mathematics, computer science, information security, electrical engineering, digital signal processing, physics, and others.
