The algorithm<BR /> stores the intermediate results of calculations performed using this context. The ECC set of APIs only support a 256-bit GF(p) cryptography system. Element size of 256 bits is supported.</P> <P>You Can reuse one throughout the entire lifetime of the enclave</P> <UL> <LI>sgx_ecc_state_handle_t ecc_handle;</LI> </UL> <P>-Surenthar</P> Wed, 15 Feb 2017 06:46:20 GMT https://community.intel.com/t5/Intel-Software-Guard-Extensions/Life-cycle-of-an-sgx-ecc-state-handle-t/m-p/1094419#M932 Surenthar_S_Intel 2017-02-15T06:46:20Z
