    • Technologies related to quorum-based Virtual Machine (VM) security are generally described. In some examples, VM data, such as a VM payload or other VM data, may be quorum-encrypted, such that a quorum of decryption keys may be used to decrypt the data. Decryption keys may be distributed among multiple VMs, with different decryption keys provided to different VMs, so that single VMs may not decrypt the VM data without decryption keys held by other VMs. To decrypt its data, a VM may assemble a quorum of decryption keys by requesting decryption keys held by other operational VMs, and the VM may then decrypt its data using the assembled quorum of decryption keys. The VM may be prevented from decrypting its data without a sufficient quorum of other operational VMs.
    • 与基于法定虚拟机(VM)安全性相关的技术通常被描述。 在一些示例中,诸如VM有效载荷或其他VM数据的VM数据可以被加法加密,使得可以使用解密密钥的数量来解密数据。 解密密钥可以分布在多个虚拟机之间,其中不同的解密密钥被提供给不同的虚拟机,使得单个虚拟机不能解密虚拟机数据,而没有由其他虚拟机保存的解密密钥。 为了对其数据进行解密,VM可以通过请求由其他操作VM保存的解密密钥来组合解密密钥的数量,然后VM可以使用组合的解密密钥解密其数据。 可以防止VM在没有足够的其他操作VM的数量的情况下解密其数据。

    • Technologies related to cache-influenced video games are generally described. In some examples, the content of video game outputs as experienced by players of a video game may be adaptively modified to make more effective use of digital assets that are loaded in a computing system cache. Cache-influenced video games may increase cache use by increasing use, within a video game, of digital assets in a cache relative to assets not in the cache, e.g., assets that are on disk or in database storage. Cached digital assets can be retrieved more efficiently than assets stored elsewhere, and therefore video game performance may be improved.
    • 通常描述与缓存影响的视频游戏相关的技术。 在一些示例中,可以自适应地修改视频游戏的玩家体验的视频游戏输出的内容,以便更有效地使用加载在计算系统高速缓存中的数字资产。 缓存影响的视频游戏可以通过在视频游戏中增加缓存中相对于不在高速缓存中的资产的数字资产(例如,在磁盘上或在数据库存储中的资产)来增加高速缓存的使用。 可以比存储在其他地方的资产更有效地检索缓存的数字资产,因此视频游戏性能可能会得到改善。

    • Technologies related to shared secret identification for secure communication are generally described. In some examples, devices may exchange hashes, such as file deduplication hashes, to identify a matching hash. The identified matching hash represents a shared data item which may be used as a shared secret to encrypt and/or decrypt subsequent secure communications between the devices. Each device retrieves the shared data item from its respective secure memory and may use the shared data item to encrypt and/or decrypt subsequent secure communications. An eavesdropper may observe the hash exchange, but will not be able to decrypt the secure communications without access to the shared data item, because hashes may be effectively non-invertible.
    • 通常描述与用于安全通信的共享秘密识别相关的技术。 在一些示例中,设备可以交换散列,例如文件重复数据消除散列,以识别匹配的散列。 所识别的匹配散列表示可以用作共享秘密以对设备之间的后续安全通信进行加密和/或解密的共享数据项。 每个设备从其相应的安全存储器检索共享数据项,并且可以使用共享数据项来加密和/或解密后续的安全通信。 窃听者可以观察哈希交换,但是不能在不访问共享数据项的情况下解密安全通信,因为散列可能是非可逆的。
