Security Strength
Security Strength: A metric associated with the amount of work required to break a cryptographic algorithm or system.
Definition
A metric associated with the amount of work required to break a cryptographic algorithm or system.
Alternative Definitions
- Definition 2
A number associated with the amount of work (that is, the number of operations) that is required to break a cryptographic algorithm or system. In this policy, security strength is specified in bits and is a specific value from the set {80, 112, 128, 192, 256}.
- Definition 3
A metric associated with the amount of work (that is, the number of operations) that is required to break a cryptographic algorithm or system.
- Definition 4
A measure of the computational complexity associated with recovering certain secret and/or security-critical information concerning a given cryptographic algorithm from known data (e.g. plaintext/ciphertext pairs for a given encryption algorithm). (SP 800-108) (NISTIR)
