Abstract: Systems and techniques are provided for gesture-based password entry to unlock an encrypted device. A gesture input from a user to a gesture interface may be received. The gesture input may be converted to gesture data which may be hashed using a hashing algorithm to obtain a table key. A table including a master key may be encrypted using the table key. The master key may include a key for decrypting a primary storage that is at least partially encrypted. A second gesture input may be receive. The second gesture input may be an input from a user to the gesture interface. The second gesture input may be converted to second gesture data which may be hashed using the hashing algorithm to obtain a key equivalent to the table key. The table including the master key may be decrypted using the key equivalent to the table key.

Abstract translation: 提供了基于手势的密码输入的系统和技术来解锁加密的设备。 可以接收从用户到手势界面的手势输入。 手势输入可以被转换成可以使用散列算法来散列以获得表格键的手势数据。 包括主密钥的表可以使用表格密钥进行加密。 主密钥可以包括用于解密至少部分加密的主存储器的密钥。 可以接收第二个手势输入。 第二手势输入可以是从用户到手势界面的输入。 第二手势输入可以被转换成可以使用散列算法来散列的第二手势数据，以获得与该表格键相当的密钥。 包括主密钥的表可以使用等价于表密钥的密钥来解密。
