Is it possible to perform curve operations directly in SGX?

[Terry_Chen]

Hi community!

sgx_tcypto provides many cryptographic primitives. But what if I just want to directly perform some curve operations like ECadd or point multiplication in enclave?

They should be basic operations in those cryptographic primitives, but not included in sgx_tcypto.h.

Hi Terry,

Apologies for the late response. The cryptographic primitives are not exposed by sgx_tcrypto.h but are supported by the IPP Crypto library, so they can be used within an enclave.

This might be useful to you: https://www.intel.com/content/www/us/en/develop/documentation/ipp-crypto-reference/top/public-key-cryptography-functions/elliptic-curve-cryptography-functions/arithmetic-of-the-group-of-elliptic-curve-points.html

Hi @Terry_Chen thank you for the post.

I am not a domain expert, however, I have a few suggestions. I have encountered the same issue while working for a leading ai development services provider. If you are really looking for specific elliptic curve operations like ECadd or point multiplication and can't find these operations readily available, you have few options,

Either go for custom implementation, where you can implement them manually within the GSX enclave.

Or depend on external libraries

Or look for documentation and forums & communities
