30 KASUMI Crypto Poll Mode Driver
31 ===============================
33 The KASUMI PMD (**librte_pmd_kasumi**) provides poll mode crypto driver
34 support for utilizing Intel Libsso library, which implements F8 and F9 functions
35 for KASUMI UEA1 cipher and UIA1 hash algorithms.
40 KASUMI PMD has support for:
44 * RTE_CRYPTO_SYM_CIPHER_KASUMI_F8
46 Authentication algorithm:
48 * RTE_CRYPTO_SYM_AUTH_KASUMI_F9
53 * Chained mbufs are not supported.
54 * KASUMI(F9) supported only if hash offset field is byte-aligned.
55 * In-place bit-level operations for KASUMI(F8) are not supported
56 (if length and/or offset of data to be ciphered is not byte-aligned).
62 To build DPDK with the KASUMI_PMD the user is required to download
63 the export controlled ``libsso_kasumi`` library, by requesting it from
64 `<https://networkbuilders.intel.com/network-technologies/dpdk>`_.
65 Once approval has been granted, the user needs to log in
66 `<https://networkbuilders.intel.com/dpdklogin>`_
67 and click on "Kasumi Bit Stream crypto library" link, to download the library.
68 After downloading the library, the user needs to unpack and compile it
69 on their system before building DPDK::
76 In order to enable this virtual crypto PMD, user must:
78 * Export the environmental variable LIBSSO_KASUMI_PATH with the path where
79 the library was extracted (kasumi folder).
81 * Build the LIBSSO library (explained in Installation section).
83 * Set CONFIG_RTE_LIBRTE_PMD_KASUMI=y in config/common_base.
85 To use the PMD in an application, user must:
87 * Call rte_eal_vdev_init("cryptodev_kasumi_pmd") within the application.
89 * Use --vdev="cryptodev_kasumi_pmd" in the EAL options, which will call rte_eal_vdev_init() internally.
91 The following parameters (all optional) can be provided in the previous two calls:
93 * socket_id: Specify the socket where the memory for the device is going to be allocated
94 (by default, socket_id will be the socket where the core that is creating the PMD is running on).
96 * max_nb_queue_pairs: Specify the maximum number of queue pairs in the device (8 by default).
98 * max_nb_sessions: Specify the maximum number of sessions that can be created (2048 by default).
