DESCRIPTION
The dca device driver is a multi-threaded, loadable hardware
driver supporting Sun PCI-based (pci108e,5454) cryptographic accelerators, such as the Sun Crypto Accelerator 1000.
The dca driver requires the presence of Solaris Cryptographic Framework for applications and kernel clients to access the provided services.
EXTENDED DESCRIPTION
The dca driver maintains the following statistics:
3desjobs
Total number of jobs submitted to the device for 3DES encryption.
3desbytes
Total number of bytes submitted to the device for 3DES encryption.
rsapublic
Total number of jobs submitted to the device for RSA public key operations.
rsaprivate
Total number of jobs submitted to the device for RSA private key operations.
dsasign
Total number of jobs submitted to the device for DSA signing.
dsaverify
Total number of jobs submitted to the device for DSA verification.
rngjobs
Total number of jobs submitted for pure entropy generation.
rngbytes
Total number of bytes of pure entropy requested from the device.
rngsha1jobs
Total number of jobs submitted for entropy generation, with SHA-1 post-processing.
rngsha1bytes
Total number of bytes of entropy requested from the device, with SHA-1 post-processing.
Additional statistics may be supplied for Sun support personnel, but are not useful to end users and are not documented here.
The dca driver can be configured by defining properties in /kernel/drv/dca.conf which override the default settings. The following properties are supported:
nostats
Disables the generation of statistics. This property may be used to help prevent traffic analysis, but this may inhibit support personnel.
rngdirect
Disables the SHA-1 post-processing of generated entropy. This may give "truer" random numbers, but it may also introduce the risk of external biases influencing the distribution of generated random numbers.
