Server-aided signatures verification secure against collusion attack
Sherman S. M. Chow, Man Ho Au, Willy Susilo · 2011
Wireless handheld devices which support e-mail and web browsing are increasingly popular. The authenticity of the information received is important, especially for business uses. In server-aided verification (SAV), a substantial part of the verification computation can be offloaded to a powerful but possibly untrusted server. This allows resource-constrained devices to enjoy the security guarantees provided by cryptographic schemes, such as pairing-based signatures, which may be too heavyweight to verify otherwise.
