FAQs
TFHE is a C/C++ library which implements a very fast gate-by-gate bootstrapping, based on [CGGI16] and [CGGI17]. The library allows to evaluate an arbitrary boolean circuit composed of binary gates, over encrypted data, without revealing any information on the data.
What is Torus fully hom*omorphic encryption? ›
An encryption scheme that supports both addition and multiplication of ciphertexts is said fully hom*omorphic, as any program can be represented as a circuit of additions and multiplications. More generally, an FHE scheme is an encryption scheme that is capable of evaluating any program over encrypted data.
What is fully hom*omorphic encryption? ›
Fully hom*omorphic encryption (FHE) is an innovative technology that can help you achieve zero trust by unlocking the value of data on untrusted domains without needing to decrypt it. Today's business data is stored across hybrid multicloud environments, exposing it to various security and privacy risks.
What is concrete ml? ›
Concrete ML is one such open-source tool that allows for privacy-preserving machine learning. Built on top of Concrete, it simplifies the use of fully hom*omorphic encryption (FHE) for data scientists to help them automatically turn machine learning models into their hom*omorphic equivalent.
What is FHE in blockchain? ›
Fully hom*omorphic. Encryption (FHE) Zama is an open source cryptography company building state-of-the-art FHE solutions for blockchain and AI. See on GithubRead the docs. or read Zama's 6 minute introduction to FHE.
What is CKKs? ›
CKKS is a somewhat hom*omorphic encryption (SHE) scheme that allows computations to be performed on encrypted data without needing to decrypt it first. Its especially designed for approximating computations on encrypted floating-point numbers, making it attractive for privacy-preserving numerical computations.

What is fully hom*omorphic encryption disadvantages? ›
Disadvantages of FHE:
- Efficiency: One of the main limitations of FHE is its efficiency. ...
- Key size: FHE typically requires a large key size, which can make it more difficult to manage and secure the keys. ...
- Complexity: FHE is a complex cryptographic technique that requires significant expertise to implement and manage.
What is the alternative to fully hom*omorphic encryption? ›
Functional Cryptography: The Alternative to hom*omorphic Encryption for Performing Calculations on Encrypted Data.
What does 32 40 concrete mean? ›
RC32/40 concrete
reinforced concrete delivers the combined tensile strength of steel and compressive strength of concrete. Versatility of application and strength over considerable spans. Typical Concrete strength: 40N/mm2 - 28 days.
C 30 is the compressive strength for a particular cube where as M 30 gives the characteristic strength of the concrete mix.
What does 1.54 mean in concrete? ›
What is 1.54 in concrete? The dry volume of concrete is 1.54, which means after applying water to the dry concrete mix, the volume of the dry concrete mix is reduced by about 54%. Dry volume = wet volume + 54% of wet volume. = 1 + (( 54/100 ) + 1 ) = 1.54.
What are fully hom*omorphic encryption methods? ›
Fully hom*omorphic encryption. A cryptosystem that supports arbitrary computation on ciphertexts is known as fully hom*omorphic 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.
What do you mean by hom*omorphic encryption? ›
hom*omorphic encryption enables complex mathematical operations to be performed on encrypted data without compromising the encryption. In mathematics, hom*omorphic describes the transformation of one data set into another while preserving relationships between elements in both sets.
What is fully hom*omorphic encryption and how will it change blockchain? ›
Fully hom*omorphic Encryption (FHE)
The most advanced type, FHE allows any number of computations to be performed on encrypted data without a predefined sequence or limit. Any computation on plaintext data, including ML and MPC, can be evaluated.
What is the difference between fully hom*omorphic encryption and zero knowledge? ›
Both FHE and ZK are cryptographic methods that allow data processing without revealing the original information. However, they operate on different principles. While FHE allows computations directly over encrypted data, ZK allows proving knowledge of information without revealing it.
