    • A secure software update provides an update utility with an update definition, a private encryption key and a public signature key to a target device. A software update package is prepared on portable media that includes an executable update program, a checksum for the program that is encrypted with a symmetrical key, an encrypted symmetrical key that is encrypted with a public encryption key and a digital signature prepared with a private signature key. The update process authenticates the digital signature, decrypts the symmetrical key using the private encryption key, and decrypts the checksum using the symmetrical key. A new checksum is generated for the executable update program and compared to the decrypted checksum. If inconsistencies are detected during the update process, the process is terminated. Otherwise, the software update can be installed with a relatively high degree of assurance against corruption, viruses and third party interference.
    • 安全软件更新为目标设备提供了具有更新定义,私有加密密钥和公共签名密钥的更新实用程序。 在便携式媒体上准备软件更新包,包括可执行更新程序,用对称密钥加密的程序的校验和,用公共加密密钥加密的加密对称密钥和用私有签名准备的数字签名 键。 更新过程认证数字签名,使用专用加密密钥解密对称密钥,并使用对称密钥解密校验和。 为可执行更新程序生成新的校验和,并与解密的校验和进行比较。 如果在更新过程中检测到不一致,则该过程终止。 否则,软件更新可以以相对较高程度的保证来安装,防止腐败,病毒和第三方干扰。

    • A watercraft hull protector for preventing damage to the lower bow surface of a waterborne craft such as a boat or jet ski, comprising a thin, elongated, flexible, but waterproof sheet-like member having a length substantially greater than the width thereof, and capable of being wound into a roll along the elongated length thereof for storage purposes. An elongated cord element coupled through a grommet located adjacent the center of a reinforced portion extending transversely across the front end portion of the sheet-like member facilitates deploying the mat on the shoreline with a substantial portion of the sheet-like member extending out of the water, traversing the muddy, rocky portion of the bank adjacent the water line, and with the rear end portion of the mat submerged below the water line. An elongated weight extending transversely across the rear end exerts a downward force on the rear end portion of the sheet-like member to retain the rearward portion of the mat in position submerged below the water line. The sheet-like member includes a surface for engagement with the beach, and an upper nonslip surface upon which a user can step while moving between the shore and the craft without treading on the muddy, rocky soil of the bank. The protector, when deployed, supports the hull of the waterborne craft and protects the hull of the craft when the craft is manipulated onto the protector during beaching.
    • 一种船体船体保护器,用于防止损坏诸如船或喷气滑雪板的水上工艺的下弓形表面,其包括细长的,细长的,柔性的但防水的片状构件,其长度基本上大于其宽度,并且能够 沿其长度方向缠绕成卷以用于存储目的。 通过位于邻近横向穿过片状构件的前端部分的加强部分的中心的护环连接的细长绳索元件有利于将垫子部署在海岸线上,其中片状构件的大部分延伸出 水,穿过邻近水线的堤坝的泥泞的岩石部分,并且垫的后端部分浸没在水线下方。 横向延伸穿过后端的细长重物在片状构件的后端部分施加向下的力,以将垫子的后部保持在浸没在水线下方的位置。 片状构件包括用于与海滩接合的表面,以及使用者可以在岸边和船只之间移动的同时,不用在堤坝的泥泞的岩石土壤上行走的同时,可以在其上滑动的上部未滑动表面。 保护器在部署时支持水上工艺的船体,并在海上操作工艺时在保护器上操作时保护船体。
