1. A computer implemented method for implementing a protocol for blocking a decryption derive request comprising:
assigning an encryption only policy to a client device;
receiving an encryption derive request from the client device;
generating a random string according to one or more predefined rules;
generating a digest parameter based on the random string and a masked secret key;
generating a blinded partial derived key based on the digest parameter; and
transmitting the blinded partial derived key to the client device, the blinded partial derived key being configured to generate a derived key for encrypting data.
