This project is funded by DARPA, with a grant of 50 million US dollars. It is mainly about data protection in digital environment
Virtual environments), an ASIC chip developed by Intel and Microsoft.
Intel is responsible for the development of chips, while Microsoft mainly integrates Intel chips into cloud services to realize the integration of software and hardware.
This chip is mainly used for homomorphic encryption, which is one of the hot research topics of encryption security in recent years. Compared with traditional encryption technology, it is more secure and helps to protect user privacy, especially in the era of AI Artificial Intelligence.
Homomorphic encryption allows the third party to do the operation directly on the encrypted data, and return the encrypted calculation results directly to the user, while the user can obtain the calculation results through decryption. In this process, the third party can provide services without obtaining the user’s encrypted data, which gives consideration to both efficiency and security.
In order to guarantee the same speed as unencrypted data, homomorphic encryption requires high-performance computing power, which usually needs to be increased by 4000-16000 times. The goal of homomorphic encryption processor developed by Intel and Microsoft is to improve the performance by 10000 times, but the specific improvement depends on the results of chip development.
