This is usually done using @ref digital_signature "digital signatures": if a -@ref certificate bearing a public key and an individual's name is signed with a key pair which you already trust, then you can -rest assure that the public key in the @ref certificate really does belong to the individual named in the @ref certificate. - -Different standards using public key cryptography employ different models for using certificates to establish trust. -Such a model, encompassing data structures, rules for their use, and users of them, may be referred to as a -@ref PKI "Public Key Infrastructure" (PKI). @ref SSL, @ref TLS and @ref SMIME "S/MIME" all use @ref X509 "X.509" v.3 certificates, and a -hierarchical @ref PKI in which users are certified by @ref CA "Certification Authorities" (CAs). - -All data which appear in the interface between the Symbian OS and the rest of the world need a transport encoding, and it -is in this form that they are sent and received.

The -certified End Entity is the \b subject of the @ref certificate: the @ref CA is the \b issuer -@li supporting @ref certificate revocation and revocation checking: if an End Entity suspects that their key has been -compromised, they contact the Certification Authority which issued it. @ref CA "CA"s publish lists of revoked certificates -(known as @ref CRL "Certificate Revocation Lists") at regular intervals, which End Entities can use to check that -certificates sent to them have not been revoked -@li publishing certificates: the most likely place for this is an LDAP directory, since @ref X509_certificate "X.509 certificates" identify -their subjects and issuers by describing a path through an X.500 directory - - -*/ \ No newline at end of file
