Abstract

Using security primitives, a novel scheme for licensing hardware intellectual properties (HWIPs) on Field Programmable Gate Arrays (FPGAs) in public clouds is proposed. The proposed scheme enforces a pay-per-use model, allows HWIP's installation only on specific on-cloud FPGAs, and efficiently protects the HWIPs from being cloned, reverse engineered, or used without the owner's authorization by any party, including a cloud insider. It also provides protection for the users’ designs integrated with the HWIP on the same FPGA. This enables cloud tenants to license HWIPs in the cloud from the HWIP vendors at a relatively low price based on usage instead of paying the expensive unlimited HWIP license fee. The scheme includes a protocol for FPGA authentication, HWIP secure decryption, and usage by the clients without the need for the HWIP vendor to be involved or divulge their secret keys. A complete prototype test-bed implementation showed that the proposed scheme is very feasible with relatively low resource utilization. Experiments also showed that a HWIP could be licensed and set up in the on-cloud FPGA in 0.9s. This is 15 times faster than setting up the same HWIP from outside the cloud, which takes about 14s based on the average global Internet speed.
云上FPGA电路ip的保护和按使用付费许可方案
利用安全原语,提出了一种新的公共云中现场可编程门阵列(fpga)硬件知识产权(HWIPs)许可方案。该方案采用按使用付费的模式,只允许HWIP安装在特定的云上fpga上,并有效地保护HWIP不被克隆、反向工程或未经任何一方(包括云内部人员)授权使用。它还为在同一FPGA上集成hip的用户设计提供保护。这使得云租户可以根据使用情况以相对较低的价格从hip供应商那里获得云中的hip许可,而不必支付昂贵的无限制的hip许可费用。该方案包括一个用于FPGA认证、hip安全解密和客户端使用的协议,而不需要hip供应商参与或泄露他们的秘密密钥。一个完整的原型测试平台实现表明,该方案在资源利用率较低的情况下是非常可行的。实验还表明,hip可以在0.9s内获得许可并在云上FPGA中建立。这比从云外设置相同的hip要快15倍,根据全球互联网的平均速度,后者大约需要14秒。
