Cryptographic computations
Web1 day ago · NEW YORK, April 13, 2024 — ACM, the Association for Computing Machinery, has named Yael Tauman Kalai the recipient of the 2024 ACM Prize in Computing for breakthroughs in verifiable delegation of computation and fundamental contributions to cryptography.Kalai’s contributions have helped shape modern cryptographic practices … A cryptosystem that supports arbitrary computation on ciphertexts is known as fully homomorphic encryption (FHE). 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. Fully homomorphic cryptosystems have great pra…

WebFeb 12, 2015 · Cryptography is the process of communicating securely in an insecure environment – i.e. where other people can listen in and control the communication channel. The message you wish to send is converted to a cipher text that appears to be gibberish unless you know the secret to unlocking it.
There are numerous cryptographic algorithms in use, but in general they can be broken into three categories: symmetric cryptography, asymmetric cryptography, and hash functions. Each has its own role to play within the cryptographic landscape. Symmetric cryptography.
