Abstract: Authentication functions are centralized in a security system to offload servers of this functionality, and to provide an end-to-end solution for secure internet transactions. The security system supports authentication functions for authenticating a server by requesting server certificates from a certificate authority, and sending server certificates to clients requesting authentication. The security system also authenticates clients by checking digital signatures, validating the client certificates, which includes checking CA signatures, checking the validity period of the signatures, maintaining a certificate revocation list (CRL), and checking client certificates against the CRL.

Abstract: A method and system is provided for accelerating the conversion process between encryption schemes. The system includes a board in a gateway. The board includes a controller to receive security parameters and data encrypted according to a first encryption scheme and control the transmission of the data. The system includes a hardware device coupled to the controller to decrypt the data and encrypt the data according to a second encryption scheme. The data is then transmitted to the controller to be forwarded out of the gateway.

Abstract: An arrangement is provided for improving the response time of a device in delivering transformed documents. Upon intercepting a request, sent by a client to a server via a device, for a document, an appropriate destination form is determined. If the destination document has been cached and the cached destination document does not need to be regenerated, the device retrieves the destination document directly from the cache and delivers it to the client. Otherwise, the document in its source format is fetched from the server and transformed into the destination document prior to its delivery to the client.
