SFB 1119: CROSSING - Cryptography-Based Security Solutions: Enabling Trust in New and Next Generation Computing Environments

密码学是安全数字流程不可或缺的推动因素，可确保机密性、完整性、身份验证和不可否认性。因此，它允许通过互联网安全地执行许多服务。然而，当前的加密解决方案并不能解决现实世界应用中遇到的所有问题。这在2014年CROSSING开始之前就已经是事实，今天仍然存在进一步的挑战。 因此，CROSSING合作研究中心的总体目标过去是，现在仍然是：提供基于密码的安全解决方案，使人们能够信任新一代和下一代 计算环境。这些解决方案将满足新环境的效率和安全要求，并将有良好的实施。即使不是密码学专家，它们也将易于为IT的开发人员、管理员和最终用户使用。实现CROSSING的目标需要来自不同学科的专业知识。交叉成员与他们不同的研究领域之间的合作精神导致了重大进展，并将继续成为关键的成功因素。CROSSING的最后阶段将达到CROSSING I和II中开发的解决方案、技术和方法的成熟度。我们将有一个连贯的框架来解决总体目标，特别是提供使用加密代码的机会，并进行合理的设计和实现。在这个阶段建立的许多原语将经受住叠加攻击，因此即使面对快速发展的量子技术也保持安全。这些解决方案将满足当前技术的功能和效率要求，并考虑到分布式云计算的额外角度。为了证明准备就绪，研究项目结构的演变通过新的转移项目领域得到了加强，在该领域中，CROSSING的结果将与行业合作伙伴一起进行完善，并转移到实际环境中。

Cryptography is an indispensable enabler for secure digital processes, ensuring confidentiality, integrity, authentication, and non-repudiation. Thereby, it allows many services to be executed securely through the Internet. Nevertheless, current cryptographic solutions do not solve all of the problems encountered in real-world applications. This has been true before CROSSING started in 2014 and further challenges still remain today. The overall goal of the Collaborative Research Center CROSSING thus was, and still is:To provide cryptography-based security solutions enabling trust in new and next generation computing environments. The solutions will meet the efficiency and security requirements of the new environments and will have sound implementations. They will be easy to use for developers, administrators, and end users of IT, even if they are not cryptography experts.Achieving the objective of CROSSING requires expertise from different disciplines. The collaborative spirit between the CROSSING members with their diverse research areas has led to significant progress and will continue to be the crucial success factor. The final phase of CROSSING will reach the maturity of the solutions, techniques, and methods developed in CROSSING I and II. We will have a coherent framework addressing the overall goal, in particular providing the opportunity to use crypto code with sound designs and implementations. Many of the primitives established in this phase will withstand superposition attacks and thus remain secure even in the face of rapidly evolving quantum technology. The solutions will meet the functional and efficiency requirements of current technology, with the extra angle of distributed cloud computing in mind. Testifying to the readiness, the evolution of the research project structure is augmented by the new transfer project area, in which the results of CROSSING will be refined with industry partners and transferred to practical settings.
