Trust

In general, trust refers to an aspect of a relationship between two parties, by which a given situation is mutually understood, and commitments are made toward actions in favor of a desired outcome. In contrast with hope, trust is almost strictly interpersonal. In contrast with faith, trust is almost always considered a subordinate material form whereas "faith" is typically reserved for a "higher power" — God, etc.

• Trust is an important concept in computer security and security engineering. In this sense, a "trusted" resource is one that you are forced by necessity to trust — that is to say, that its failure will compromise the security or integrity of the system. The name of the Trusted Computing platform is said to be derived from this sense.
• In cryptography, trust is either of two related concepts - how much one trusts another person to introduce keys, and how confident one is that a given key has a given owner. These determinations are often made via a web of trust.
