1. Storage apparatus, comprising:
- an archive memory centrally archiving data for a plurality of computers;
an encryption processor, which is configured to receive and encrypt data transmitted from one or more computers for storage in the archive memory; and
a one-way link, coupling the encryption processor to the archive memory so as to enable the encryption processor to write the encrypted data to the memory but not to read from the memory,wherein the one-way link is physically configured so as to permit data transmission in only one direction, from the processor to the memory, andwherein the memory and the encryption processor are connected in a manner allowing direct transmission only from the encryption processor to the memory, and not from the memory to the encryption processor.

Abstract
Storage apparatus (20) includes a memory (30) and an encryption processor (28), which is configured to receive and encrypt data transmitted from one or more computers (24) for storage in the memory. A one-way link (32) couples the encryption processor to the memory so as to enable the encryption processor to write the encrypted data to the memory but not to read from the memory.

13. A method for data storage, comprising:
-
receiving data transmitted from one or more computers for storage in an archive memory centrally archiving data for a plurality of computers; encrypting the received data using an encryption processor before passing the data to the archive memory; conveying the encrypted data from the encryption processor to the archive memory over a one-way link, which permits the encryption processor to write the encrypted data to the memory but not to read from the memory, wherein the one-way link is physically configured so as to permit data transmission in only one direction, from the processor to the memory, and wherein the memory and the encryption processor are connected in a manner allowing direct transmission only from the encryption processor to the memory, and not from the memory to the encryption processor; and storing the encrypted data in the memory. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
