If the 503 * group is not supported by your implementation, then the original Mbed TLS 504 * implementation of ecp_double_jac() is used instead, unless this fallback 505 * behaviour is disabled by setting MBEDTLS_ECP_NO_FALLBACK (in which case 506 * ecp_double_jac() will return MBEDTLS_ERR_ECP_FEATURE_UNAVAILABLE). 507 * 508 * The function prototypes and the definition of mbedtls_ecp_group and 509 * mbedtls_ecp_point will not change based on MBEDTLS_ECP_INTERNAL_ALT, so your 510 * implementation of mbedtls_internal_ecp__function_name__ must be compatible 511 * with their definitions. 512 * 513 * Uncomment a macro to enable alternate implementation of the corresponding 514 * function. 515 */ 516 /* Required for all the functions in this section */ 517 //#define MBEDTLS_ECP_INTERNAL_ALT 518 /* Turn off software fallback for curves not supported in hardware */ 519 //#define MBEDTLS_ECP_NO_FALLBACK 520 /* Support for Weierstrass curves with Jacobi representation */ 521 //#define MBEDTLS_ECP_RANDOMIZE_JAC_ALT 522 //#define MBEDTLS_ECP_ADD_MIXED_ALT 523 //#define MBEDTLS_ECP_DOUBLE_JAC_ALT 524 //#define MBEDTLS_ECP_NORMALIZE_JAC_MANY_ALT 525 //#define MBEDTLS_ECP_NORMALIZE_JAC_ALT 526 /* Support for curves with Montgomery arithmetic */ 527 //#define MBEDTLS_ECP_DOUBLE_ADD_MXZ_ALT 528 //#define MBEDTLS_ECP_RANDOMIZE_MXZ_ALT 529 //#define MBEDTLS_ECP_NORMALIZE_MXZ_ALT 530 531 /** 532 * \def MBEDTLS_ENTROPY_HARDWARE_ALT 533 * 534 * Uncomment this macro to let Mbed TLS use your own implementation of a 535 * hardware entropy collector. 536 * 537 * Your function must be called \c mbedtls_hardware_poll(), have the same 538 * prototype as declared in library/entropy_poll.h, and accept NULL as first 539 * argument. 540 * 541 * Uncomment to use your own hardware entropy collector. 542 */ 543 //#define MBEDTLS_ENTROPY_HARDWARE_ALT 544 545 /** 546 * \def MBEDTLS_AES_ROM_TABLES 547 * 548 * Use precomputed AES tables stored in ROM. 549 * 550 * Uncomment this macro to use precomputed AES tables stored in ROM. 551 * Comment this macro to generate AES tables in RAM at runtime. 552 * 553 * Tradeoff: Using precomputed ROM tables reduces RAM usage by ~8kb 554 * (or ~2kb if \c MBEDTLS_AES_FEWER_TABLES is used) and reduces the 555 * initialization time before the first AES operation can be performed. 556 * It comes at the cost of additional ~8kb ROM use (resp. ~2kb if \c 557 * MBEDTLS_AES_FEWER_TABLES below is used), and potentially degraded 558 * performance if ROM access is slower than RAM access. 559 * 560 * This option is independent of \c MBEDTLS_AES_FEWER_TABLES. 561 */ 562 #define MBEDTLS_AES_ROM_TABLES 563 564 /** 565 * \def MBEDTLS_AES_FEWER_TABLES 566 * 567 * Use less ROM/RAM for AES tables. 568 * 569 * Uncommenting this macro omits 75% of the AES tables from 570 * ROM / RAM (depending on the value of \c MBEDTLS_AES_ROM_TABLES) 571 * by computing their values on the fly during operations 572 * (the tables are entry-wise rotations of one another). 573 * 574 * Tradeoff: Uncommenting this reduces the RAM / ROM footprint 575 * by ~6kb but at the cost of more arithmetic operations during 576 * runtime.
