That is, + * there will be no node file in /dev, no way for a user-mode program to access + * the driver, no way for a user program to access the device directly. + * + * With the exception of #scc_monitor_security_failure(), all routines are + * 'synchronous', i.e. they will not return to their caller until the requested + * action is complete, or fails to complete. Some of these functions could + * take quite a while to perform, depending upon the request. + * + * Routines are provided to: + * @li encrypt or decrypt secrets - #scc_crypt() + * @li trigger a security-violation alarm - #scc_set_sw_alarm() + * @li get configuration and version information - #scc_get_configuration() + * @li zeroize memory - #scc_zeroize_memories() + * @li Work on wrapped and stored secret values: #scc_alloc_slot(), + * #scc_dealloc_slot(), scc_load_slot(), #scc_decrypt_slot(), + * #scc_encrypt_slot(), #scc_get_slot_info() + + * @li monitor the Security Failure alarm - #scc_monitor_security_failure() + * @li stop monitoring Security Failure alarm - + * #scc_stop_monitoring_security_failure() + * @li write registers of the SCC - #scc_write_register() + * @li read registers of the SCC - #scc_read_register() + * + * The driver does not allow "storage" of data in either the Red or Black + * memories. Any decrypted secret is returned to the user, and if the user + * wants to use it at a later point, the encrypted form must again be passed + * to the driver, and it must be decrypted again. + * + * The SCC encrypts and decrypts using Triple DES with an internally stored + * key. When the SCC is in Secure mode, it uses its secret, unique-per-chip + * key. When it is in Non-Secure mode, it uses a default key. This ensures + * that secrets stay secret if the SCC is not in Secure mode. + * + * Not all functions that could be provided in a 'high level' manner have been + * implemented. Among the missing are interfaces to the ASC/AIC components and + * the timer functions. These and other features must be accessed through + * #scc_read_register() and #scc_write_register(), using the @c \#define values + * provided. + * + * Here is a glossary of acronyms used in the SCC driver documentation: + * - CBC - Cipher Block Chaining. A method of performing a block cipher. + * Each block is encrypted using some part of the result of the previous + * block's encryption. It needs an 'initialization vector' to seed the + * operation. + * - ECB - Electronic Code Book. A method of performing a block cipher. + * With a given key, a given block will always encrypt to the same value. + * - DES - Data Encryption Standard. (8-byte) Block cipher algorithm which + * uses 56-bit keys. In SCC, this key is constant and unique to the device. + * SCC uses the "triple DES" form of this algorithm. + * - AIC - Algorithm Integrity Checker. + * - ASC - Algorithm Sequence Checker. + * - SMN - Security Monitor. The part of the SCC responsible for monitoring + * for security problems and notifying the CPU and other PISA components. + * - SCM - Secure Memory. The part of the SCC which handles the cryptography. + * - SCC - Security Controller. Central security mechanism for PISA. + * - PISA - Platform-Independent Security Architecture. + */ + +/* Temporarily define compile-time flags to make Doxygen happy. */ +#ifdef DOXYGEN_HACK +/*! @defgroup scccompileflags SCC Driver compile-time flags + * + * These preprocessor flags should be set, if desired, in a makefile so + * that they show up on the compiler command line. + */ +/*! @addtogroup scccompileflags */ + +/*! @{ */ +/*! + * Compile-time flag to change @ref smnregs and @ref scmregs + * offset values for the SCC's implementation on the MX.21 board. + * + * This must also be set properly for any code which calls the + * scc_read_register() or scc_write_register() functions or references the + * register offsets. + */ +#define TAHITI +/*! @} */ +#undef TAHITI + +#endif /* DOXYGEN_HACK */ + +/*!
