Sentence examples for distinguishable ciphertexts from inspiring English sources

Gender: distinguishable ciphertexts.

CPI approaches that outsource distinguishable ciphertexts can be used to protect against an attacker with BKS knowledge because distinguishable ciphertexts do not contain any order information, which means that the value range of an attribute cannot be used to map distinguishable ciphertexts onto plaintext values.

If the attacker has background knowledge of the data (BKD), they can reveal plaintext values based on distinguishable ciphertexts as we show in the following example.

However, once the attacker can observe range queries and range query results, they may again be able to infer the order of distinguishable ciphertexts.

Since the outsourced values are distinguishable ciphertexts, bucketization can be considered secure against a D&BKS-attacker that is only able to access the data and has background knowledge of the data's schema.

We differentiate between the following security properties: Content Confidentiality: The content confidentiality provided by an approach reflects how the protected attribute values are represented at the SP. We differentiate between order-preserving ciphertexts, distinguishable ciphertexts, and indistinguishable ciphertexts.

Example: If the attacker knows that "m" is the most frequent gender in the data, this plaintext value can be mapped to the most frequent distinguishable ciphertext η in Table 2.

Once the ciphertexts are distinguishable, BKD knowledge can be applied to reveal the confidential attribute values.

Since deterministic ciphertexts are distinguishable and only equality selections are evaluated, the approach protects against Q&BKS-attackers, i.e., attackers with background knowledge of the data's schema (cf. Figure 3).

If the attacker knows that 20000 is the most frequent salary, they cannot use this knowledge on Table 2 because the ciphertexts of salary are not distinguishable.

The colors now distinguishable.
