bearerderived

Bearerderived is a term used in information security and digital identity to describe data, tokens, or permissions that are created or derived directly from a bearer credential or the state of possession, rather than from a persistent, named identity. The concept emphasizes possession-based trust, where validity rests on the bearer having a valid credential at the time of use.

The word is a portmanteau of bearer and derived, and appears in practitioner discussions and some academic writings from the early 2020s onward to distinguish artifacts rooted in possession from those tied to a specific identity.

Bearerderived artifacts are typically associated with transient validity, revocation mechanisms, and transfer by possession. They are designed to be verifiable without revealing the bearer’s identity, reducing the need to bind actions to a fixed user name, while raising risk if possession is lost or stolen.

Common contexts include session or device tokens, ephemeral cryptographic proofs, and access permissions generated during authentication events. These artifacts often rely on cryptographic material derived from the bearer’s credentials and are intended for short lifetimes or tightly scoped use.

Because control is tied to possession, bearerderived artifacts require strong possession protection and rapid revocation strategies. They are complementary to named, attribute-based, or role-based credentials, not a replacement, and are evaluated alongside risk, usability, and compliance considerations.
