What Specific Role Does Encryption Play in Maintaining a Digital Chinese Wall?

Encryption plays a crucial role by securing sensitive, non-public order information both in transit and at rest. Data related to large client orders is encrypted, and only authorized systems or personnel (on the side of the wall that handles execution) have the decryption keys.

This prevents employees on the other side of the wall (e.g. proprietary traders) from accessing the data, even if they gain unauthorized network access, thus reinforcing the separation.
