Abstract
Software can be downloaded securely using a multi-encryption method, where the decryption is completed when the software is executed. In one aspect, a multi-encrypted data item is received. One or more of the encryptions on the multi-encrypted data item is decrypted, yielding a partially decrypted data item. The partially decrypted data item is stored in a reserved portion of a storage medium. The partially decrypted data item is fetched from the storage medium and decrypted to yield the data item. The decryption can be performed using one or more circuits that implement multiple decryption processes, including multiple algorithm-key combinations.
