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
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.

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.
