The Ontology at a glance

An a-z index of RSA Ontology terms, by class (categories or types) and by property.

Classes: | RSAKey | RSAPrivateKey | RSAPublicKey |

Properties: | modulus | private_exponent | public_exponent |

The evolution of the RSA Ontology is best considered in terms of the stability of individual vocabulary terms, rather than the specification as a whole. As terms stabilise in usage and documentation, they progress through the categories 'unstable', 'testing' and 'stable'. Older terms are marked 'archaic' which allows the possibility of older forms to become modern again.

Cross-reference for Cert classes and properties

The RSA Ontology introduces the following classes and properties. There is a link at the top of this document to the RDF/XML and RDF/N3 versions.

Classes: | RSAKey | RSAPrivateKey | RSAPublicKey |

Properties: | modulus | private_exponent | public_exponent |


Classes

Class: rsa:RSAKey

RSA Key - The union of the public and private components of an RSAKey. Usually those pieces are not kept together
Status:
unstable
Properties include:
rsa:modulus
Sub class of
cert:Key
Has sub class
rsa:RSAPublicKey
rsa:RSAPrivateKey
OWL Class

[#] [back to top]


Class: rsa:RSAPrivateKey

RSA Private Key - A Private Key in the RSA framework
Status:
unstable
Properties include:
rsa:private_exponent
Sub class of
rsa:RSAKey
OWL Class

[#] [back to top]


Class: rsa:RSAPublicKey

RSA Public Key - The RSA public key. Padded message m are encrypted by applying the function modulus(power(m,exponent),modulus)
Status:
unstable
Properties include:
rsa:public_exponent
Sub class of
rsa:RSAKey
OWL Class

[#] [back to top]


Properties

Property: rsa:modulus

modulus - The modulus of an RSA public and private key. This is defined as n = p*q
Status:
unstable
Domain:
rsa:RSAKey
Range:
cert:int
Datatype Property

[#] [back to top]


Property: rsa:private_exponent

private - The exponent used to decrypt the message calculated as public_exponent*private_exponent = 1 modulo totient(p*q) The private exponent is often named 'd'
Status:
unstable
Domain:
rsa:RSAPrivateKey
Range:
cert:int
Datatype Property

[#] [back to top]


Property: rsa:public_exponent

public_exponent - The exponent used to encrypt the message. Number chosen between 1 and the totient(p*q). Often named 'e' .
Status:
unstable
Domain:
rsa:RSAPublicKey
Range:
cert:int
Datatype Property
