DESCRIPTION

28       The  dca  device  driver  is a multi-threaded, loadable hardware driver
29       supporting Sun  PCI-based  (pci108e,5454)  cryptographic  accelerators,
30       such as the Sun Crypto Accelerator 1000.
31
32
33       The  dca  driver requires the presence of  Solaris Cryptographic Frame‐
34       work for applications and kernel clients to access  the  provided  ser‐
35       vices.
36

EXTENDED DESCRIPTION

38       The dca driver maintains the following statistics:
39
40       3desjobs        Total  number  of jobs submitted to the device for 3DES
41                       encryption.
42
43
44       3desbytes       Total number of bytes submitted to the device for  3DES
45                       encryption.
46
47
48       rsapublic       Total  number  of  jobs submitted to the device for RSA
49                       public key operations.
50
51
52       rsaprivate      Total number of jobs submitted to the  device  for  RSA
53                       private key operations.
54
55
56       dsasign         Total  number  of  jobs submitted to the device for DSA
57                       signing.
58
59
60       dsaverify       Total number of jobs submitted to the  device  for  DSA
61                       verification.
62
63
64       rngjobs         Total number of jobs submitted for pure entropy genera‐
65                       tion.
66
67
68       rngbytes        Total number of bytes of pure  entropy  requested  from
69                       the device.
70
71
72       rngsha1jobs     Total  number of jobs submitted for entropy generation,
73                       with SHA-1 post-processing.
74
75
76       rngsha1bytes    Total number of bytes of  entropy  requested  from  the
77                       device, with SHA-1 post-processing.
78
79
80
81       Additional  statistics  may be supplied for Sun support personnel,  but
82       are not useful to end users and are not documented here.
83
84
85       The dca driver can  be  configured  by  defining  properties  in  /ker‐
86       nel/drv/dca.conf  which  override  the  default settings. The following
87       properties are supported:
88
89       nostats      Disables the generation of statistics. This  property  may
90                    be  used  to  help  prevent traffic analysis, but this may
91                    inhibit support personnel.
92
93
94       rngdirect    Disables the SHA-1 post-processing of  generated  entropy.
95                    This  may  give  "truer"  random  numbers, but it may also
96                    introduce the risk of external biases influencing the dis‐
97                    tribution of generated random numbers.
