Séminaire

Séminaire confiance numérique Over the years, several identity-based cryptosystems using bilinear pairings have been proposed. Many schemes, based on bilinear pairings, suffer from key escrow problems and require a secure channel for private key issuance. In this talk, we will discuss on a binding-blinding technique, which can be used for solving the problem of key escrow in identity-based cryptosystem and can help in eliminating the requirement of secure channel for the private key issuance.
