Technique mainly employed for factorization based cryptosystems to hide information. Usually blinding involves using a multiplicative homomorphic property of the cipher, it may be used to realize blind-signatures. It's also commonly used to protect cryptosystems like RSA and Rabin-Williams against timing-attacks.

Blinding an ECDSA private key without learning the private key

The security of the basic version of Split-ECDSA (SECDSA) is based on the security of 'raw ECDDSA signing', i.e. the way how signing is done in practice. Here the application calling the cryptographic …
