The phrase "a secure distance" is correct and usable in written English.
It can be used to describe a safe or appropriate amount of space between two objects or individuals, often in contexts related to safety or comfort.
Example: "During the fire drill, we were instructed to maintain a secure distance from the building."
Alternatives: "a safe distance" or "an appropriate distance".
In reaction to this attempt, the Secret Service began keeping Ford at a more secure distance from anonymous crowds, a strategy that may have saved his life seventeen days later; as he left the St. Francis Hotel in downtown San Francisco, Sara Jane Moore, standing in a crowd of onlookers across the street, pointed her.38-caliber revolver at him.

In the years following Gaveston's death, however, civil conflict in England rarely seemed far away, and it is currently believed that Thomas probably intended to create a secure retreat, a safe distance away from Edward's forces in the south.
Bringer et al. [68] propose a secure Hamming distance calculation for biometric application, called as SHADE.
Osadchy et al. [66] propose a secure Hamming distance calculation scheme based on Pailler homomorphic encryption for face biometrics.
Thus, it is easier to calculate the secure distance, which results in more convenient to realize security monitor and control in distribution systems.
The following related work describes secure distance computation algorithms.
Protocol 5 defineSteps overall ABAC system.
Homomorphic cryptosystems can be used for secure distance computation [12, 13], e.g., in the context of image retrieval [14], fingerprint matching [15], and face recognition [16].
We distinguish between secure distance computation methods which are suitable to compare load profiles and other related work including oblivious transfer and smart-grid literature with tariff selection and profile matching.
