Arcadia — Full Disk Encryption Daemon

01 Problem

A Swedish security company needed a macOS full disk encryption solution using their proprietary cryptographic algorithms. The solution required a background daemon performing real-time encryption/decryption at the disk level, with TCP socket communication for remote management and policy enforcement from a central security server.

03 Solution

Developed a macOS full disk encryption daemon for Arcadia Inc (Sweden) using Objective-C and low-level macOS system APIs. Implemented proprietary cryptographic algorithms for real-time disk encryption, TCP socket communication for remote policy management, and a background daemon architecture for continuous disk protection. The system operated at the kernel/system level requiring deep understanding of macOS disk I/O and security frameworks.

04 Outcomes

06 Constraints

• Proprietary cryptographic algorithm implementation
• Real-time disk I/O encryption without performance degradation
• Background daemon stability and reliability
• Remote management via TCP sockets

07 Innovation

Implemented proprietary cryptographic algorithms in a macOS full disk encryption daemon with real-time I/O interception, requiring deep system-level programming and security expertise.
