Cryptographic hardware for encryption and key storage WebSEAL, using GSKit for SSL communication and key management, provides interface support for cryptographic hardware. Cryptographic hardware can provide one or both of the following features: v Accelerated and secure SSL encryption and decryption tasks for performance improvements during multiple online transactions v Accelerated and secure digital certificate key storage and management for highly secure architecture during online transactions WebSEAL and GSKit support the following interfaces to this cryptographic hardware: v BHAPI (RSA Security, Inc.’s API supporting its BSAFE product) v PKCS#11 (Public Key Cryptographic Standard) Some cryptographic hardware supports both interfaces; some cryptographic hardware supports only one of the interfaces. In general, WebSEAL (and GSKit) uses the BHAPI interface to support encryption and decryption. WebSEAL (and GSKit) uses PKCS#11 to support both encryption/decryption and key storage. WebSEAL supports several hardware devices for selected platforms. Consult the IBM Tivoli Access Manager for e-business Release Notes to obtain the latest information on platform support for these hardware cards. Cryptographic accelerator cards v nCipher nForce 300 v Rainbow CryptoSwift eCommerce Accelerator v IBM 4960 Key Storage v nCipher nForce 300 v IBM 4758 v Eracom Orange The following matrix illustrates the relationship between functionality and interface support for each of these cards: BHAPI PKCS#11 SSL Acceleration v Rainbow CryptoSwift v nCipher nForce 300 v IBM 4960 v nCipher nForce 300 Key Storage v IBM 4758 v nCipher nForce 300 v Eracom Orange The Rainbow CryptoSwift and nCipher nForce 300 (using BHAPI) are used for public key operations (RSA key decryption). Keys are not stored on the accelerator device, but are stored in the pdsrv.kdb file. Accelerator devices are used to speed up the public key cryptographic functions of SSL. Hardware acceleration frees up the server processor, increases server throughput, and shortens wait time. The 32 IBM Tivoli Access Manager for e-business: WebSEAL Administration Guide
Rainbow CryptoSwift and nCipher nForce accelerators incorporate faster performance by providing more concurrent secure transactions. With the PKCS#11 interface, RSA keys are stored on a cryptocard to ensure authentication. The IBM 4758 and Eracom Orange perform only as key storage devices. The nCipher nForce device can either perform just acceleration or it can perform both acceleration and key storage with PKCS#11 support. The IBM 4758, Eracom Orange, and nCipher nForce devices (with PKCS#11 support) ensure that keys are completely inaccessible to the outside world. Keys are never revealed in an unencrypted form because they are stored on the hardware, providing enhanced key protection and authentication. Hardware cryptographic acceleration and key storage apply to the following WebSEAL connections: v Browser to WebSEAL v WebSEAL to back-end junctioned server Conditions and prerequisites IBM 4758–023 On Windows 2000, the IBM 4758–023 cryptographic card has an access limitation of 32 worker threads. Therefore, WebSEAL must be configured to use no more than 32 worker threads. The recommendation is 30 worker threads. The default setting for worker threads at WebSEAL installation time is 50 worker threads. Refer to “Managing worker thread allocation” on page 41 for information about worker thread configuration. Additional monitoring threads are used for any junctions configured with the –K option (WebSEAL authenticates with a client-side certificate) where the key (certificate) is stored on the IBM 4758 hardware. In this situation, further reduce the number of worker threads by one for each SSL –K junction using keys stored on the IBM 4758 card. Configuring Cipher engine and FIPS mode processing You can use the WebSEAL configuration file to specify the Cipher engine used by GSKit. [ssl] base-crypto-library = Default Valid values for this entry are: v Default This value tells GSKit to select the optimal cryptographic base to use. For WebSEAL Version 5.1, this is ICC v ICC v RSA Specify RSA when using a BHAPI (Bsafe Hardware API) CryptoCard such as Rainbow CryptoSwift. The BHAPI interface is not supported by ICC. When the WebSEAL deployment environment includes previous version (before Version 5.1) WebSEAL servers, consider using this setting because RSA was used by previous versions of GSKit for cryptographic operations. Note: PKCS#11 is available in all modes, except when FIPS is enabled. Chapter 2. WebSEAL server configuration 33
