“…This can be an arbitrary combination of DES, TripleDES, and plaintext communication, respectively ECB and CBC operational mode for each VC and communication direction transmit or receive. Providing arbitrary combinations of encryption algorithms (DES or TripleDES) and operational modes (ECB or CBC) is referred to as algorithm agile encryption [28], robustness agile encryption respectively [29]. HADES employs on-chip session key storage and management blocks which utilise CAM techniques to identify a certain encryption context, and random access memory (RAM) techniques to store the session keys and the initialisation vectors (IV s).…”

Abstract:Broadband networks based on the asynchronous transfer mode (ATM) are emerging rapidly. Both the technological component in terms of ATM infrastructure, as well as the area of applications requiring Quality of Services (QoS) by the means of bandwidth or delay constraints are covered by a variety of projects and products. However, given the increasing interest in applications such as governmental communication, transmission of medical information, or commercial applications, the necessity of providing secure means of delivering sensitive contents is apparent. In this paper, we focus on security services in ATM networks. The variety of different approaches and solutions are categorised by the means of its common and distinct functionality, as well as certain advantages and disadvantages are discussed. In addition, the standardisation efforts by the leading group in that area--the A TM F O11Ulr-al"e outlined. Finally, the essentials of the project SCAN 3 are given, resulting in a comprehensive solution to security services in ATM networks.

“…Beyond that publications, in [8] a CAM-based approach to key agility is discussed. In [9], algorithm-agile encryption is introduced, where the encryption unit not just switches between keys, it even enables different encryption algorithms to be applied to different VCs. Finally, the concept of a ATM confidentiality system for 10 Gbps OC-192 is discussed in [10].…”

Abstract:With the increasing deployment of asynchronous transfer mode (ATM) in both local area network (LAN), and wide area network (WAN) environments the interest in secure means of transferring sensitive information over A TM increases. Given potential application fields requiring Quality of Services (QoS) provided by ATM, as divers as transferring medical images, linking branch offices to company networks, or governmental networks transferring sensitive citizen information, security is not only a desired option, it is rather an indispensable necessity. The weakness of solutions to security in ATM networks has been recognised early. Cryptography is the tool of choice to achieve secure communications and a couple of proposals appeared to integrate cryptographic functions into ATM. Products have been developed which at the beginning faced the uncertainty of missing standards frameworks. However, this issue has been made up, as the ATM Forum has recently approved the Security Specification 1.0 which is an fact a comprehensive standardisation effort building the buttress for interoperable products. In this tutorial, the ATM security arena is surveyed. It first gives an explanatory overview of A TM as a technology and addresses the challenges specific to A TM when aiming to migrate ATM to a secure infrastructure. Basing on these challenges, promising approaches to achieve security in ATM networks are described. By assessing the specific advantages and disadvantages, a comparison of the approaches against the ATM Forum Security Specification is made. In its final part, the tutorial surveys products

“…As ATM cells are statistically multiplexed between VCs, replacing the session key may be required for each ATM cell. Further requirements may even strive for assigning different encryption algorithms to each VC, such as DES and Triple-DES, which is referred to as algorithm-agile encryption [8]. Actually, the encryption unit presented in this paper allows to uniquely assign the encryption context including the operational mode to each connection which is called context-agile encryption [6].…”

Abstract. The presented Triple-DES encryptor is a single-chip solution to encrypt network communication. It is optimized for throughput and fast switching between virtual connections like found in ATM networks. A broad range of optimization techniques were applied to reach encryption rates above 155 Mbps even for Triple-DES encryption in outer CBC mode. A high-speed logic style and full-custom design methodology made first-time working silicon on a standard 0.6 µm CMOS process possible. Correct functionality of the prototype was verified up to a clock rate of 275 MHz.
