Abstract: A processor includes a decode unit to decode an instruction that is to indicate a page of a protected container memory, and a storage location outside of the protected container memory. An execution unit, in response to the instruction, is to ensure that there are no writable references to the page of the protected container memory while it has a write protected state. The execution unit is to encrypt a copy of the page of the protected container memory. The execution unit is to store the encrypted copy of the page to the storage location outside of the protected container memory, after it has been ensured that there are no writable references. The execution unit is to leave the page of the protected container memory in the write protected state, which is also valid and readable, after the encrypted copy has been stored to the storage location.

Abstract: Instructions and logic provide advanced paging capabilities for secure enclave page caches. Embodiments include multiple hardware threads or processing cores, a cache to store secure data for a shared page address allocated to a secure enclave accessible by the hardware threads. A decode stage decodes a first instruction specifying said shared page address as an operand, and execution units mark an entry corresponding to an enclave page cache mapping for the shared page address to block creation of a new translation for either of said first or second hardware threads to access the shared page. A second instruction is decoded for execution, the second instruction specifying said secure enclave as an operand, and execution units record hardware threads currently accessing secure data in the enclave page cache corresponding to the secure enclave, and decrement the recorded number of hardware threads when any of the hardware threads exits the secure enclave.

Abstract: The present application is directed to establishing ownership of a secure workspace (SW). A client device may provide a SW data structure (SWDS) to a SW configurator. A SWDS may comprise a hash of an original SW and a public key, and may be signed by a private key corresponding to the public key. The SW configurator may cause an execution container (EC) to be generated including a SW initiated using the SWDS. The client device may claim SW ownership using a request (signed by the private key) transmitted along with a copy of the public key. SW ownership may be determined by an ownership determination module that verifies the signature of the request using the public key received with the request, determines a hash of the received public key and compares the hash of the received public key to a hash of the public key in the SWDS.

Abstract translation: 本申请旨在建立安全工作区（SW）的所有权。 客户端设备可以向SW配置器提供SW数据结构（SWDS）。 SWDS可以包括原始SW和公共密钥的散列，并且可以由对应于公开密钥的私有密钥进行签名。 SW配置程序可能会导致生成执行容器（EC），包括使用SWDS启动的SW。 客户端设备可以使用与公钥的副本一起发送的请求（由私钥签名）来声明SW所有权。 SW所有权可以由所有权确定模块确定，该模块使用通过该请求接收到的公开密钥来验证请求的签名，确定所接收的公开密钥的散列，并将接收到的公开密钥的散列与公钥的散列进行比较 在SWDS。
