Cryptographic Security (CRYPTOSEC)

Below is a sneak peek of this content!

What Is CRYPTOSEC? Cryptographic Security (CRYPTOSEC) is the discipline of protecting information through encryption, authentication, and key management so that even if communications or data are intercepted, they cannot be read, altered, or credibly forged by unauthorized parties. In simple terms: CRYPTOSEC assumes the enemy will see your traffic — and makes sure it’s useless to them. Unlike EMCON or TRANSEC, which aim to reduce detection, CRYPTOSEC focuses on survivability after compromise. Why CRYPTOSEC Matters for Preparedness Groups Most preparedness communications today rely on: Cell phones Messaging apps Radios (digital and analog) Email Shared documents and plans All of these are vulnerable to: Interception Metadata analysis Replay attacks Spoofing Device capture or loss In a crisis — natural disaster, civil unrest, infrastructure failure, or targeted surveillance — unencrypted communications become intelligence feeds. CRYPTOSEC ensures: Confidentiality – outsiders can’t read your messages Integrity – messages can’t be altered unnoticed Authentication – you know who you’re talking to Non-repudiation – actions and orders can be verified For preppers, this translates to trust, coordination, and operational continuity when normal systems fail. CRYPTOSEC vs Related Disciplines CRYPTOSEC does not replace other security disciplines — it complements them: COMSEC – Overall communications security (umbrella)...
