WebFeb 23, 2024 · Cryptographic computing offers a completely different approach to protecting data-in-use. Instead of using isolation and access control, data is always cryptographically protected, and the processing happens directly on the protected data. Webat hand. Examples of this kind of approach include works on threshold cryptography (see Section 6) where efﬁcient multiparty computation protocols are devised forthe task of shared generation of digital signatures. Another possible approach, the one which we follow in this paper, is to go back to the original works

Such a scheme enables the construction of programs for any desirable functionality, which can be run on encrypted inputs to produce an encryption of the result. Since such a program need never decrypt its inputs, it can be run by an untrusted party without revealing its inputs and internal state.
