PRNGsid
PRNGsid is a concept for a family of pseudorandom number generators that derives its output from a session identifier (SID). The aim is to provide deterministic, reproducible streams of numbers for the same SID while allowing different SIDs to produce distinct sequences. This approach is useful in systems that require session-level isolation or traceability, such as simulations, testing environments, or multi-tenant workflows.
The design generally features a compact internal state that is updated through a mixing core combining bitwise
Seeding and usage are central to PRNGsid. A SID is processed by a mixing function to initialize
Security considerations are important. PRNGsid is typically not intended as a cryptographically secure generator, and it
Applications include simulations, reproducible experiments, testing pipelines, and scenarios where session-based seeding provides convenient isolation. Implementations
