Abstract
A system and method is provided for accessing secure files by local client devices. An exemplary method comprises receiving an access request to access an encrypted file on a client device, in response to the access request, transmitting a decryption request to decrypt a remote processing portion of a block of the encrypted file, receiving, in response to the decryption request, the decrypted remote processing portion of the block of the encrypted file, and receiving a local decryption key and applying the local decryption key to decrypt one or more local portions of the block of the encrypted file to obtain a fully decrypted block of the encrypted file.
