The Western Kunlun Range in northern Qinghai-Tibet Plateau is composed of the North Kunlun Terrane,the South Kunlun Terrane and the Karakorum-Tianshuihai Terrane. Here we report zircon SHRIMP and LA-ICP-MS U-Pb ages of some metamorphic and igneous rocks and field observations in order to pro-vide a better understanding of their Precambrian and Palaeozoic-early Mesozoic tectonic evolution. Based on these data we draw the following conclusions: (1) The paragneisses in the North Kunlun Terrane are likely of late Mesoproterozoic age rather than Palaeoproterozoic age as previously thought,representing tectonothermal episodes at 1.0―0.9 Ga and ～0.8 Ga. (2) The North Kunlun Terrane was an orogenic belt accreted to the southern margin of Tarim during late Mesoproterozoic to early Neopro-terozoic,the two episodes of metamorphisms correspond to the assemblage and breakup of Rodinia respectively. (3) The Bulunkuole Group in western South Kunlun Terrane,which was considered to be the Palaeoproterozoic basement of the South Kunlun Terrane by previous studies,is now subdivided into the late Neoproterzoic to early Palaeozoic paragneisses (khondalite) and the early Mesozoic metamorphic volcano-sedimentary series; the paragneisses were thrust onto the metamorphic vol-cano-sedimentary series from south to north,with two main teconothermal episodes (i.e.,Caledonian,460―400 Ma,and Hercynian-Indosinian,340―200 Ma),and have been documented by zircon U-Pb ages. (4) In the eastern part of the South Kunlun Terrane,a gneissic granodiorite pluton,which intruded the khondalite,was crystallized at ca. 505 Ma and metamorphosed at ca. 240 Ma. In combination with geochronology data of the paragneiss,we suggest that the South Kunlun Terrane was a Caledonian accretionary orogenic belt and overprinted by late Paleozoic to early Mesozoic arc magmatism.

Efficient and Secure Multi-Signature Scheme Based on Trusted Computing

引用

Wuhan University Journal of Natural Sciences 2008年第2期13卷 180-184页

作者： HAO Liming YANG Shutang lu songnian CHEN Gongliang Department of Electronic Engineering Shanghai Jiao TongUniversity Shanghai 200240 China School of Information Security Engineering Shanghai JiaoTong University Shanghai 200240 China

A new multi-signature scheme was proposed with the extension of the direct anonymous attestation （DAA） protocol supported by trusted computing （TC） technology. Analysis and simulation results show that the signer＇s privacy is well protected with dynamic anonymity, the public key and signatures have length independent of the number of signature members, new signers are allowed to join the signature without modifying the public key, and attacks caused by secret key dumping or leaking can be avoided.

A Group-Based Fingerprinting Scheme for Digital Wholesale and Retail

引用

China Communications 2014年第10期11卷 126-135页

作者： ZHAO Yong ZHANG Aixin lu songnian School of Electronic Information and Electrical Engineering Shanghai Jiao Tong University Minhang 200240 Shanghai R R. China

Prior group-based fingerprinting achieves better detection performance when colluders are from the same group. But in digital wholesale and needs to be identified retail, the middleman as well as customers especially against group colluding attack. The group tracing is neglected in previous works. In this paper, we propose a novel multimedia group fingerprint to trace malicious middlemen along with customers. We explore the quality of the non degenerate linear shift register sequence （NDLSRS） which is convenient in group initialization and management. The theoretic analysis and simulation experiment results show that NDLSRS has good resistance against attacks from colluding groups/ members even after its volume expanded.

A Mechanism Based on Reputation in P2P Networks to Counter Malicious Packet Dropping

引用

Wuhan University Journal of Natural Sciences 2011年第5期16卷 405-408页

作者： PENG Hao lu songnian LI Jianhua ZHANG Aixin ZHAO Dandan Electronic Engineering Department Shanghai Jiao TongUniversity Shanghai 200240 China School of Information Security Engineering Shanghai JiaoTong University Shanghai 200240 China

In P2P （Peer-to-Peer） networks, some malicious peers can impact on overall networks performance. One of the malicious behaviors of these peers is malicious packet dropping. In this paper, our focus is to detect and to exclude peers that misbehave by dropping some or all packets. Here, we propose a reputation-based mechanism for solving the problem efficiently. The proposed mechanism uses both direct reputation information and indirect reputation information to compute comprehensive reputation of a peer. At the same time, history reputation information is also taken into account to provide faults tolerance capability and we regulate the imprecision based on the fact that the cause of packet dropping can be complex. Finally, the peers with bad comprehensive reputation can be detected easily and then will be excluded from the network. In this way, our proposed mechanism improves the per- formance of P2P networks without increasing computational overhead.

A Method to Implement Full Anonymous Attestation for Trusted Computing Platform

引用

Wuhan University Journal of Natural Sciences 2007年第1期12卷 101-104页

作者： HAO Liming SUN Xun YANG Shutang lu songnian School of Electronic Information and Electrical EngineeringShanghai Jiao Tong University Shanghai 200240 China

Trusted computing （TC） technology is brought out by trusted computing group （TCG） to make computing as safe and reliable as people expect. Attestation is one main function specified by TCG, which is the means by which a trusted computer assures a remote computer whose platform is not tampered with. There are two protocols that implement attestation without disclosing the platform＇s real identity, which are Privacy CA-based protocol and direct anonymous attestation （DAA） protocol. However, in the first protocol the privacy CA is the bottleneck and the platform＇s identity will be disclosed if the privacy CA is compromise, while DAA protocol can do profiling when dealing with rogue hardware device. In this paper, we propose a DAA-extended new approach to ensure full anonymous attestation that can not only detect a rogue TPM, but also reveal rogue TPM＇s real identity.

The eclogite, discovered in Liuyuan, occurs as lenticular enclave within granitic gneiss. It has typical features of eclogite in petrology and mineralogy. The eclogite provides an important wirdow to reconstruct the tectonic border of the Tarim block. The granitoids, located in Baihu area, yield U-Pb zircon ages of 1 660—2 000 Ma (Palaeoproterozoic), which irrplies an early Precambrian basement in the area.

Introduction to The Regional Geology of China In 2008, a new project concerning the recompilation of The Regional Geology of China (RGC) was assigned by the Chinese Geological Survey (CGS) and undertaken by the Institute of Geology, Chinese Academy of Geological Sciences (CAGS). Li Tingdong, an academician of the Chinese Academy of Sciences (CAS), is the chief leader and chief scientist of the project. The last time The Regional Geology of China was compiled was in the 1980s (Cheng, 1994).

笔者在"关于板块运动启动时间的争论"一文(陆松年等,2016)基础上,参阅公开发表的部分文章,介绍了前板块岩浆洋和停滞盖研究的新进展,并再次讨论有关板块运动启动时间的不同认识和观点。根据太阳系30个类地行星天体图像资料,硅酸盐质行星体在它的生命期由于冷却和岩石圈增厚似乎经历过多种构造样式,包括岩浆洋、多类型停滞盖以及板块构造。硅酸盐类行星由于增生、分异、撞击和放射性活动,使星体变热,发生熔融反应而形成"岩浆洋"。硅酸盐星球体早期很可能是大面积但寿命很短的岩浆洋,之后的星球可能受两种构造模型控制:停滞盖构造和板块构造。已有资料表明,停滞盖构造是类地行星的主要构造类型,而板块构造在类地行星中是十分罕见的。停滞盖构造是一个单一的、围绕天体的板块,基本由硅酸盐质岩石圈组成。停滞盖构造有三种主要变化形态——热管、滴状及柱状体、拆沉及上涌流。板块构造启动时间从>4.4Ga到0.85Ga至少有11种不同观点:认为板块构造始于冥古宙的有1种、始于始-古太古代的有3种、始于中-新太古代的有4种、始于古元古代有1种、始于新元古代的有2种。本文重点介绍了地球冥古宙-太古宙板块运动启动的地质学证据和特点。

鲁西地区是我国新太古代经典的花岗岩-绿岩带出露地区之一,前人已积累了丰硕的构造地层、同位素地质年龄、地球化学及成矿作用等方面的资料,并对这一时期的地球动力学特征进行了讨论.通过研究"洋板块地质"的思路综合前人已获得的区域地质调查研究资料,表明泰山岩群镁铁质火山岩演化是一套由科马提岩-拉斑玄武岩和拉斑玄武岩、钙碱性玄武岩及安山岩等两类岩石组合复合而成的火山岩系,反映了相对早期形成与洋内地幔柱有关的科马提岩向相对晚期与弧有关的钙碱性玄武岩-安山岩的演化过程;新太古代初期形成岛弧型英云闪长岩带到新太古代中期形成分异型奥长花岗岩,则反映了俯冲过程中的花岗岩演化特点;新太古代晚期硅质高镁玄武岩(高镁玄武安山岩)的确定则是活动大陆边缘岩浆弧的产物;泰山岩群中红宝石(刚玉)的发现,进一步指示其形成的背景与新太古代板块构造俯冲作用有关,为鲁西存在新太古代洋板块地质遗迹提供了地质学证据.
