Continues the work from #25:
Uses the DH key from
newTaskEncryptionKeyto encrypt data submitted to the enclave. Timestamped geolocation data is JSON serialized into a string and encrypted. It later gets decrypted inside the enclave for processing: it gets indexed by userId in a HashMap, storing all datapoints submitted. This means that a newer submission for the same user, will overwrite previous data.Implemented quote/report through remote attestation. Works beautifully.
Implemented findMatch for a given user. Returns data encrypted so that only the user can decrypt.
A working version of the enclave is available at https://safetrace.enigma.co
