The Innovative Patent Increases Security and Efficiency by Managing Certificates
in a Public Key Infrastructure
HELSINKI, FINLAND and WELLESLEY, Mass. - Sept. 23, 2008 - SSH Communications
Security Corp. (OMX:SSH1V), a world-leading provider of enterprise security
solutions and end-to-end communications security, and the original developer of
the Secure Shell protocol, today announced the issuance of a key patent covering
a new, streamlined process of issuing certificate revocation lists (CRLs) and
eliminating the need for private keys to be present during the periodic
publishing of CRLs.
The U.S. Patent No. 7,356,693, “Method for Producing Certificate Revocation
Lists,” is designed to create an easier way to operate a Public Key
Infrastructure (PKI) hierarchy while reducing the practical work needed to
produce and distribute CRLs. Producing multiple CRLs in volume at one time,
keeping them secure until needed and publishing them in the directory, is a
cost-effective and more efficient best-practice than creating individual CRLs at
various times, also, easing the burden on administrators.
By arranging the root certificate authority (CA) to produce multiple CRLs in
advance and issuing one of these pre-generated CRLs at a time to the directory
system, new CRLs can be made available for PKI clients without having the CA
private key available. The CA private key is only needed during the initial CRL
pre-generation, and whenever new certificates are generated or revoked. The new
technology provides greater security since access to the CA private keys is only
needed when new certificates are generated or revoked.
“SSH is proud to be the leader in this effort to increase security for PKI
users,” said Timo Rinne, Chief Technology Officer, SSH Communications Security.
“This innovative patent can help to reduce costs significantly, and add to the
efficiency of the PKI certificate management process.”
SSH Communications Security has been granted 5 U.S. patents, and 2 active
patents are pending, for the end-to-end communications security technology.
