Compressive Sensing is a promising technology, which provides a very efficient way to sample and compress sensoric data. Sensoric data are very sensitive under security aspects und should be kept confidential. Therefore solutions have been developed and published, which provide confidentiality by encryption. Nevertheless these encryption algorithms specify the encryption of single input vectors only. This results in identical cipher text vectors for identical clear text vectors. This is not acceptable under security aspects. Therefore, this research project will develop modes of operation for Compressive Sensing based encryption, which define, how compressive sensing based encryption can be used in practice. The modes of operation of block ciphers specified in ISO 10116 can be taken as an example, but the modes of operation specified in ISO 10116 can not be applied, because the properties of the input vectors, which enable compressive sensing, would be lost by feedback to the input vectors. The new modes to be developed have to be analysed, compared and evaluated under the quality of service aspects of synchronisatiion, throughput, scalability, delay, etc. Additionally a security analysis has to be achieved for each mode, because the security level of encryption should not be reduced by the modes of operation. The modes of operation will be integrated in a real Compressive Sensing SAR application (Synthetic Aparature Radar) and tested.Following the research of modes of operation for compressive sensing based encryption, modes of operation will be developed for compressive sensing based encryption including authentication. These mode provide an "Authenticated Encryption" (comparable to ISO 19772), i.e. the data integrity and authenticity of data can be verified by the receiver. The integrity and authentication of origin of sensoric data are very important, because the actions and reactions of information processing and process control depends on the trustworthiness of the input data. It is the overall goal of the project, to perform sampling and compression (compressive sensing), encryption, data integrity and authentication of origin in one single step, if the input vectors have the appropriate properties for compressive sensing. The modes of operation respect the requirements of synchronization, throughput, scalability, robustness, security, etc.

压缩传感是一项很有前途的技术，它提供了一种非常有效的采样和压缩传感数据的方法。传感器数据在安全方面非常敏感，应保密。因此，已经开发并发布了通过加密提供机密性的解决方案。然而，这些加密算法仅指定单个输入向量的加密。这会导致相同的明文向量产生相同的密文向量。这在安全方面是不可接受的。因此，该研究项目将开发基于压缩感知的加密的操作模式，该模式定义了如何在实践中使用基于压缩感知的加密。可以以ISO 10116中规定的分组密码的操作模式为例，但是不能应用ISO 10116中规定的操作模式，因为对输入向量的反馈将丢失能够实现压缩感测的输入向量的属性。必须在同步、吞吐量、可扩展性、延迟等服务质量方面对要开发的新模式进行分析、比较和评估。此外，必须对每种模式进行安全分析，因为加密的安全级别不应因操作模式而降低。这些操作模式将被集成到真实的压缩感知SAR应用（合成孔径雷达）中并进行测试。在研究基于压缩感知的加密的操作模式之后，将开发用于基于压缩感知的加密（包括认证）的操作模式。这些模式提供“经过验证的加密”（相当于 ISO 19772），即数据的完整性和数据的真实性可以由接收方验证。传感数据的完整性和来源认证非常重要，因为信息处理和过程控制的动作和反应取决于输入数据的可信度。该项目的总体目标是，如果输入向量具有压缩感知的适当属性，则一步执行采样和压缩（压缩感知）、加密、数据完整性和来源认证。操作模式尊重同步、吞吐量、可扩展性、鲁棒性、安全性等要求。
