SPADE: Selective and PArtial DEcryption using Functional Encryption

SPADE is an FE-based scheme that enables running selective and partial decryption queries over vectors of ciphertexts.

To see two real-world applications of SPADE please check the usescases directory.

Notes

1. Curators are required to specify both the number of users and the maximum number of entries allowed for each plaintext vector. Users must encrypt their data as a vector of integers, ensuring that none of the values are zero.
2. Be careful when defining the users' data vector using make(); this method assigns the zero value to the elements during initialization.

Changing the protobuf structure

If you want to modify the protobuf structure, please first change the following file:

./spadeproto/spade.proto

and then run the proto compiler command as follows to generate the new protobuf files:

protoc --go_out=. --go-grpc_out=. spade.proto 

Testing Instruction

go test     

Benchmarking Instruction
