We outline a secure and efficient methodology to do threshold distributed decryption for
LWE based Fully Homomorphic Encryption schemes. Due to the smaller parameters used in …

Multiparty fully homomorphic encryption (MFHE) schemes enable multiple parties to
efficiently compute functions on their sensitive data while retaining confidentiality. However …

Threshold signatures improve both availability and security of digital signatures by splitting
the signing key into N shares handed out to different parties. Later on, any subset of at least …

Threshold signatures have recently seen a renewed interest due to applications in
cryptocurrency while NIST has released a call for multi-party threshold schemes, with a …

Multiparty homomorphic encryption (MHE) enables a group of parties to encrypt data in a
way that (i) enables the evaluation of functions directly over its ciphertexts and (ii) enforces a …

Recent works have investigated the relevance and practicality of using techniques such as
Differential Privacy (DP) or Homomorphic Encryption (HE) to strengthen training data privacy …

Protocols for distributed (threshold) key generation (DKG) in the discrete-logarithm setting
have received a tremendous amount of attention in the past few years. Several synchronous …

In LWE based cryptosystems, using small (polynomially large) ciphertext modulus improves
both efficiency and security. In threshold encryption, one often needs" simulation security" …

Fully homomorphic encryption (FHE) enables arithmetic operations to be performed over
plaintext by operations on undecrypted ciphertext. The Chillotti-Gama-Georgieva …

随着物联网, 云计算, 人工智能的应用与普及, 数据安全与隐私保护成为人们关注的焦点.
全同态加密, 作为隐私安全问题的有效解决办法, 允许对加密数据执行任意同态计算 …
