This is a cryptographic system that uses two types of keys:

is secret (only known by the entity) and is used to sign the message.

• private key

• public key

• Certificate Authority (CA)

• Validation

is mathematically derived from the private key — is made available to anyone on the internet and used to verify signatures.

• private key

• public key

• -

  Certificate Authority (CA)

• Validation

This trusted third-party organization issues digital certificates, proving that the public key indicated on the certificate indeed belongs to the named subject. CA allows other parties to rely upon signatures about the private key corresponding to the certified public key.

• private key

• public key

• Certificate Authority (CA)

• Validation

Digital certificates issued as part of your PKI allow individual users, organizations, and web site operators to confidently validate the identity of each party in an Internet transaction.

• authenticate identity

• verify integrity

• ensure privacy

A digital certificate ensures that the message or document the certificate "signs" has not been changed or corrupted in transit online.

• authenticate identity

• verify integrity

• ensure privacy

Digital certificates protect information from interception during Internet transmission.

• authenticate identity

• verify integrity

• ensure privacy

PKI digital certificates replace easily guessed and frequently lost user IDs and passwords to streamline intranet log-in security and reduce the Management Information Systems (MIS) overhead.

• authorize access

• authorize transaction

• support for non-repudition

With PKI solutions, your enterprises can control access privileges for specified online transactions.

• authorize access

• authorize transaction

• support for non-repudiation

Digital certificates validate their users‘ identities, making it nearly impossible to later repudiate a digitally "signed" transaction, such as a purchase made on a web site.

• authorize transaction

• support for non-repudiation
