The Secure Shell (SSH) Transport Layer Protocol

E901635

network security protocol transport layer protocol in SSH architecture

The Secure Shell (SSH) Transport Layer Protocol is the core low-level component of SSH that provides secure, encrypted, and integrity-protected communication over an insecure network, forming the foundation for higher-level SSH services.

How this entity was disambiguated

This entity first appeared as the object of triple T11033198 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.
