What this concept builds on and what it makes possible — derived from the atlas’s dependency, causal and structural relations, not from every related edge.
System context
Digital signatureis part ofCryptographyEstablished
Digital signatures prove authorship.
Mechanism: Signing with a private key produces a mark anyone can verify with the matching public key, but no one can forge.
Encryptionis part ofCryptographyEstablished
encryption is part of cryptography.
Mechanism: Encryption is the core technique of cryptography: it scrambles a message with a key so only someone with the matching key can read it.

Public-key cryptographyis part ofCryptographyEstablished
Open Public-key cryptography →
public-key cryptography is part of cryptography.
Mechanism: Public-key cryptography is a branch of cryptography using a pair of keys: one public to lock a message, one private to unlock it.

Symmetric-key cipheris part ofCryptographyEstablished
Symmetric ciphers are a core of cryptography.
Mechanism: One shared key both scrambles and unscrambles the message, so only key-holders can read it.
Structural role & consequence
Interpreted from the current atlas graph — what the connections mean, not just how many there are.
Currently dark in the atlas: no key date stored · 5 of 5 of its relations lack claim-level evidence.
atlas representation · Describes the current Thinking OS representation, not the state of the world.
Structural neighbourhood: 5 → 21 → 58 concepts reachable within 3 hops.
structural · Structural reach — being reachable is not the same as being understood.
All 5 of its relationships stay within its own discipline — a field-specific concept in the current atlas.
structural · Structural graph analysis — not a claim of importance, causation or history.

Strengths & constraints
Constraints
- Evidence coverage currently thin in the atlas — few of its relationships carry claim-level evidence. atlas representation
- No dated history stored — the atlas records no key date for this concept. atlas representation
Conditions
- Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural
Seen through each discipline
How this concept sits in each of its fields — derived from its real connections in the graph, not asserted.
Through this lens it connects to Information, Public-key cryptography, Digital signature and Encryption.
