Background
Currently, a cloud computing server generally completes an encryption and decryption function required by an application through pure software or a hardware encryption and decryption accelerator card inserted into a PCIe slot of the server. In the prior art, encryption and decryption are realized by pure software, which is mainly realized by executing an X86 instruction, as shown in FIG. 1. The encryption and decryption instruction and the data are stored in the DDR, the X86 core runs a software instruction to complete encryption and decryption of the data in the DDR, and the result is also stored in the DDR. By using the enhancement technology provided by Intel and adopting pure software to realize encryption and decryption, the encryption and decryption requirements with lower capacity can be met.
However, if the encryption and decryption traffic is higher, the encryption and decryption need to be implemented by hardware, i.e., using a hardware encryption and decryption accelerator card, as shown in fig. 1. However, this structure has the following problems: 1. although the parallelism of data processing is improved by Intel through technologies such as SIMD, hyper-threading, out-of-order execution, special instruction set extension and the like, the parallelism of finally obtained data processing is not high due to the nature of serial execution of software instructions, so that the encryption and decryption are realized with low efficiency. 2. Due to the fact that design methods such as operation component sharing, Cache sharing, branch prediction, hyper-threading and the like are adopted in a great number of micro-architecture designs, a great number of side channels with information leakage exist in a CPU and a whole processor system. In the cloud computing environment, multiple virtual machines share one set of physical execution resources, so that the utilization rate of computing resources is improved, and meanwhile, the encryption and decryption which are used as basic information security guarantees also face extremely serious security problems because side channel attacks cannot be avoided. 3. The PCIe expansion card needs to be inserted into a PCIe slot of the server, and can only be used by an application program on the server, and cannot be shared by multiple servers or blades, which is inconvenient for the cloud computing environment to flexibly schedule encryption and decryption resources.
Accordingly, the prior art is yet to be improved and developed.

As can be seen from fig. 2, the encryption and decryption blade in fig. 2 includes: the hardware encryption and decryption modules are used for encrypting and decrypting data; and the PCIe Switch chip is connected with the hardware encryption and decryption modules.
In particular, due to the space limitation in a general server, the PCIe slots are limited, and 1 to 2 PCIe hardware encryption and decryption acceleration cards are inserted at most. In order to provide higher-capacity encryption and decryption services, a plurality of hardware encryption and decryption modules are stacked in the encryption and decryption blade. And a plurality of hardware encryption and decryption modules on the encryption and decryption blade are connected with the PCIeSchw chip through PCIe slots, can be completely increased and decreased according to needs, and have very good expandability.
In the present invention, the hardware encryption and decryption module supports a Single Root I/O Virtualization (Single I/O Virtualization) standard SR-IOV issued by PCI-SIG (PCI-Special Interest Group), and can virtualize one Physical encryption and decryption Function (PF) into hundreds of logical encryption and decryption functions (VF). The encryption and decryption resources are finely divided. The cloud operating system can very flexibly schedule such fine-grained encryption and decryption resources to the X86 computing blades in the server. And the hardware encryption and decryption module is connected with the PCIe Switch chip through a PCIe slot, and due to the high bandwidth and low delay of PCIe, the service provided by the encryption and decryption blade can be ensured.
In this embodiment, the PCIe Switch chip supports an I/O Virtualization standard MR-IOV (Multi-root I/O Virtualization), facilitating any X86 blade of the upstream port to share any encryption/decryption module accessing the downstream port.
Preferably, the encryption and decryption blade further comprises a monitoring management module, wherein the monitoring management module is connected with the hardware encryption and decryption modules and is used for monitoring module power supplies and module running states in the encryption and decryption blade. The encryption and decryption blade supports hot plug, and a PCIe card is additionally inserted without opening a computing blade in a server. The whole encryption and decryption blade is inserted into the server, and then the operation can be started immediately.
