47486 分布式拒绝服务（DDoS）是攻击者通过入侵云内虚拟机组成攻击网络，以威胁多租户云系统安全的攻击。 An attacker compromised a number of VMs in the cloud to form his own network to launch a powerful distri-buted denial of service (DDoS) attack. DDoS attack is a serious threat to multi-tenant cloud.
47487 多租户云系统 DDoS 攻击检测难点在于如何确定攻击源虚拟机和攻击目标，尤其当攻击目标为云内主机时。 It is difficult to detect whichVM in the cloud are compromised and what is the attack target, especially when the VM in the cloud is the victim.
47488 提出一种基于熵度量的 DDoS 攻击检测方法，根据云环境特点在优先定位攻击源基础上再确定攻击目标，检测多租户云系统内发起的 DDoS 攻击。 ADDoS detection method was presented suitable for multi-tenant cloud environment by identifying the malicious VM at-tack sources first and then the victims.
47489 提出分布式检测架构， A distributed detection framework was proposed.
47490 利用检测代理发现潜在攻击源端的可疑攻击流量， The distributed agent detects thesuspicious VM which generate the potential DDoS attack traffic flows on the source side.
47491 检测服务器识别 DDoS 攻击的真正攻击流。 A central server confirms thereal attack flows.
47492 理论和实验分析验证了提出方法的可行性和有效性。 The feasibility and effectiveness of the proposed detection method are verified by experiments in themulti-tenant cloud environment.
47493 非对称密钥密码体制（公钥密码体制）在当今信息安全领域中扮演着重要的角色。 Asymmetric key cryptosystem plays an significant role in the field of information security.
47494 与传统的公钥密码体制相比，基于标识的公钥密码体制简化了证书的管理，减少系统通信量和存储开销。 Compared with tra-ditional public key cryptosystem, the public key crypto system based on identity simplifies certificate management andreduces system communication and storage cost.
47495 在分析了已有加密安全方案以及对比不同安全方案的优点及缺点后，介绍一种使用国密算法、基于标识密钥技术的证书集成管理平台及其所独具的优势。 A management platform and its unique merits were introduced afteranalyzing the current security schemes and comparing their various advantages and defects.
