Abstract: Homomorphic cryptography on numerical values in digital computing is described, including converting a numerical value encoded in a bit string of a first size to another bit string of a second size, which is different from the first size; encrypting the numerical value in the another bit string to produce a ciphertext; and storing the ciphertext.
Abstract translation: 描述了数字计算中的数值的同态密码学，包括将第一大小的比特串中编码的数值转换成与第一大小不同的第二大小的另一比特串; 加密另一位串中的数值以产生密文; 并存储密文。

Abstract: Processing a query, includes, at a client, receiving a user-generated query having a plurality of recognizable terms, securing the user-generated query to generate an encrypted query, so that the plurality of recognizable terms generated by the user-generated query cannot be determined by a server, transmitting the encrypted query to the server, to perform the query on encrypted data comprising a mix of regular data and secure data previously provided by the client, wherein at least one of selection criteria of the query and identities of selected records of the query result cannot be determined by the server, and interpreting a result of the query provided by the server, and providing an output of the query to the user having the plurality of recognizable terms.
Abstract translation: 处理查询，包括在客户端接收具有多个可识别术语的用户生成的查询，保护用户生成的查询以生成加密查询，使得由用户生成的查询生成的多个可识别术语不能 由服务器确定，将加密的查询发送到服务器，以对包括常规数据和先前由客户端提供的安全数据的混合的加密数据执行查询，其中查询的选择标准和所选择的身份的至少一个 查询结果的记录不能由服务器确定，并且解释由服务器提供的查询的结果，并且向具有多个可识别术语的用户提供查询的输出。
