We initiate a formal study of individual cryptography Informally speaking, an algorithm Alg is individual if in every implementation of Alg there always exists an individual user that has full knowledge of the cryptographic secrets S used by Alg. In particular, it should be infeasible to design implementations of this algorithm that would hide the secret S by distributing it between a group of parties using an MPC protocol, or via outsourcing it to a trusted execution environment.
