17835 然而，数据外包导致数据所有权与管理权分离，如何保证数据的安全性成为云计算中亟待解决的关键问题。 However, outsourcing data to the remote server suffers from data security concerns, becausethe server may try to learn the information of the outsourced data as much as possible for commercial purpose.
17836 传统的加密技术虽然可以保证数据的机密性，但是在密文中如何执行有意义的检索操作成为一个巨大的挑战。 The traditional encryption technique can protect the confidentiality of users’ data, however, it leads to the lossof search ability over the encrypted data.
17837 为了保证数据机密性的同时实现密文数据的高效检索，可搜索加密技术应运而生。 Fortunately, searchable encryption, as a promising solution, enablesthe server to perform keyword-based search over encrypted data.
17838 近年来，可搜索加密方案的设计日趋多样化，旨在提高方案的实用性。 Recently, the design of searchable encryptionscheme is becoming more and more diversified, aiming to improve the practicability of the scheme.
17839 该文主要围绕目前可搜索加密方案的研究热点，从4个方面展开阐述，具体包括：单关键词检索、多模式检索、前/后向安全检索和可验证检索。 This paper focuses on the current research for searchable encryption scheme in four aspects, including single keyword search, multi-modal search, forward/ backward secure search and verifiable search.
17840 该文主要介绍和分析具有代表性的研究成果，总结最新研究进展及提炼关键技术难点，最后对未来的研究方向进行展望。 This paper mainlyintroduces and analyzes the representative research results, summarizes the latest research progress and keytechnical difficulties, and finally prospects the future research direction.
17841 DNA链置换技术具有自发性、并行性、可编程性、动态级联性的特点，在DNA计算中占据重要的地位。 DNA strand displacement technology has the characteristics of spontaneity, parallelism,programmability and dynamic cascade, which is widely used to solve mathematical problems.
17842 DNA链置换技术被广泛的应用于解决数学问题，该文采用格雷码编码方式结合DNA链置换技术设计了两位减法器，扩展DNA减法运算。 In this paper, a two-bit subtracter is designed by using Gray code encoding and DNA strand displacement technology to extendthe operation of DNA subtraction.
17843 最后利用Visual DSD软件模拟两位减法器，该电路达到预期的功能，且具有并行性和可扩展性，可与其他生化电路结合使用。 Finally, Visual DSD software is used to simulate the two-bit subtracter. Thecircuit, with the strong parallelism and expansibility, achieves the expected function. It can be used incombination with other biochemical circuits.
17844 加速度和下降速度的存在使机动平台大斜视SAR的成像参数存在明显的2维空变性，严重影响场景的聚焦深度。 The existence of acceleration and descent velocity makes the imaging parameters of high-squint SAR mounted on maneuvering platform have obvious two-dimensional spatial variability, which affects seriously the focus depth of the scene.
