Aki’s work shows the difficulty of designing for the future, even as an ideal. So, given our knowledge of today’s requirements, how might we design a cryptographic primitive that would be applicable to another 70 years down the road?
When designing for a future time, the first question that we ask ourselves is, “What will the world look like?” In a few decades, we might find ourselves in a situation where it is desirable to support not just a single person but to support many people all over the world. With a worldwide, multi-national, single identity, it may be desirable to be able to perform biometric identification, as well as access control. The Identity Bridge project is designed as a means of integrating the many and varied systems necessary to provide identity services in a single, single-reputation, user-centric identity. Consider, for example, how one might provide user-to-user identity in a network of clients. Identities could be synchronized across multiple entities.
Integrate security frameworks, protocols, and concepts to enable both single sign-on and multi-sign-on. Features include: SSO access control, single identity, multi-factor authentication, key management, and transport security. Identity Bridging consists of Security Services, Trust Analyses, Authentication Matrices, Bridging Matrices, Security Logging, and Bridging Protocols. The Security Services are designed to provide authentication, confidentiality, integrity, and access control. Trust Analyses provide a logic-based framework to prove the correctness of cryptographic key creation and the correctness of security-relevant computations performed by the Security Services. The Authentication Matrices provide templates for designing cryptographic authentication mechanisms and for planning and constructing cryptographic protocols. The Bridging Matrices provide a standardized framework for describing key management protocols. The Bridging Protocols standardize the interaction between components at each end of a network connection, e.g., client-to-service, service-to-service, and at a key-management protocol layer.
We believe that Identity Bridging will be the new standard for Internet identity. While mobile technology is advancing rapidly, the Web remains the dominant platform for Internet commerce and communication. The Identity Bridge standards are designed to provide privacy and integrity, including confidentiality, integrity, availability, and freshness, as well as authentication and authorization of clients and services.
The theoretic ideal of mixing is the design of a new primitive that has superior properties to both components. Theoretic ideal mixing is one of the reasons behind asymmetric cryptography. Most examples of theoretic ideal mixing are designed to provide better properties than stream ciphers without needing additional components such as block ciphers. This may provide a more efficient approach to cryptographic implementation.
ICM is a cipher that has been widely used for the encryption of International Telegraph Coded Messages. It was designed by Claude Shannon in 1948. ICM is the symmetric-key cipher first described in Shannon’s paper A Mathematical Theory of Cryptography . This cipher is specified in the European GSM Standard.
Early in the development of DES, the National Bureau of Standards (now the National Institute of Standards and Technology) performed a comparison of the security of DES with other published designs. The results of their tests showed the key length to be a critical parameter. The NBS judged DES to be completely inadequate for military applications. They concluded, “A 70-bit key is approximately equivalent to a 20-bit key.” If one accepts that a 20-bit key is adequate for commercial applications, then one must conclude that DES is grossly insufficient for military applications. The defense community, however, is aware of the NBS report and treats NBS as authoritative. In the past few years, many military agencies have actually employed 24-bit DES in applications where it did not make sense to use a robust cryptosystem.
