    • PURPOSE: A write block device for hard disk forensics is provided to minimize heat generation of a hard disk and thus to prevent thermal damage of the hard disk even in a long time work. CONSTITUTION: A write block device for hard disk forensics comprises an ATA interface unit(11), a USB interface unit(12), a display unit, a power port(16), a current limit circuit, a mount(19), a cooler(18), and a controller. The ATA interface unit and the USB interface unit are used for communications with a host computer. The display unit shows the various operation states of the write block device and a hard disk. The power port supplies power to the hard disk. The current limit circuit prevents over current from flowing from the power port to the hard disk. The mount loads the hard disk. The cooler cools the heat generated in the hard disk during operation. The controller processes the various kinds of control signals and data transmitted from the host computer.
    • 目的:提供用于硬盘取证的写入块设备,以尽量减少硬盘的发热,从而即使在长时间的工作中也能防止硬盘的热损坏。 构成:用于硬盘取证的写入块装置包括ATA接口单元(11),USB接口单元(12),显示单元,电源端口(16),限流电路,安装座(19), 冷却器(18)和控制器。 ATA接口单元和USB接口单元用于与主机通信。 显示单元显示写入块装置和硬盘的各种操作状态。 电源端口为硬盘供电。 电流限制电路可防止过电流从电源端口流向硬盘。 安装装载硬盘。 冷却器在运行期间冷却硬盘中产生的热量。 控制器处理从主机传送的各种控制信号和数据。

    • The present invention relates to a system (70, 80) and a method for a key block based authentication comprising a plurality of drive units (3) comprising a plurality of subsets, wherein a drive unit (3) has a set of node keys (KNd) and an identifier (IDd) indicating the subsets said drive unit (3) is part of and wherein an application unit (1) has a key block (AKB). In order to allow identification of a hacked drive unit (3) in order to revoke the hacked drive unit (3) from said key block based authentication, wherein said system is to a large extent compatible with existing systems and methods for a key block based authentication, a system is proposed comprising:-a plurality of drive units (3) comprising a plurality of subsets, wherein a drive unit (3) has a set of node keys (KNd) and an identifier (IDd) indicating the subsets said drive unit (3) is part of,-an application unit (1) having a key block (AKB) comprising a plurality of pairs of authorization and authentication keys (KAx, KRauthx), wherein each pair of keys is associated with one of said subsets,-a communication means (72) for submitting said identifier (IDd) from said drive unit (3) to said application unit (1) and for submitting an authorization key (KAx) from said application unit (1) to said drive unit (3), and-an authentication means (54) for authenticating said drive unit (3) and said application unit (1) by means of a pair of keys, wherein said application unit (1) comprises a selecting means (62) for selecting said pair of keys from said key block (AKB) corresponding to said identifier (IDd), wherein said drive unit (3) comprises a decoding means (52) for deriving said authentication key (KRauthx) of said pair of keys from said authorization key (KAx) of said pair of keys by means of said set of node keys (KNd).
    • 本发明涉及一种用于基于密钥块的认证的系统(70,80)和方法,其包括多个包括多个子集的驱动单元(3),其中驱动单元(3)具有一组节点密钥 KNd)和指示所述驱动单元(3)的子集的标识符(IDd),并且其中应用单元(1)具有密钥块(AKB)。 为了允许识别被入侵的驱动单元(3),以便从所述基于密钥块的认证中撤销被入侵的驱动单元(3),其中所述系统在很大程度上与现有的系统和基于密钥块的方法兼容 提出了一种系统,其包括: - 多个包括多个子集的驱动单元(3),其中驱动单元(3)具有一组节点密钥(KNd)和指示所述子集的所述驱动器的标识符(IDd) 单元(3)是具有包括多对授权和认证密钥(KAx,KRauthx)的密钥块(AKB)的应用单元(1)的一部分,其中每对密钥与所述子集之一相关联 , - 用于将所述标识符(IDd)从所述驱动单元(3)提交到所述应用单元(1)并将授权密钥(KAx)从所述应用单元(1)提交给所述驱动单元(1)的通信装置(72) 3),以及用于认证所述驱动单元(3)的认证装置(54) d表示应用单元(1),其中所述应用单元(1)包括用于从对应于所述标识符(IDd)的所述密钥块(AKB)中选择所述一对密钥的选择装置(62) 其特征在于,所述驱动单元(3)包括解码装置(52),用于通过所述一组节点密钥(KNd)从所述一对密钥的所述授权密钥(KAx)中导出所述一对密钥的所述认证密钥(KRauthx) 。
