The Wired Equivalent Privacy (WEP) uses the 64 bit RC4 secret key stream cipher as its layer 2 security protocol. Although the underlying RC4 cipher is secure, the potential reuse...
A universally composable (UC) blind signature functionality requres users to commit to the message to be blindly signed. It is thereby impossible to realize in the plain model. Th...
Abstract. Public-key cryptography is a prerequisite for security in distributed systems and for reliable electronic commerce. The protection of public keys against attacks is the A...
The Ideal-Cipher Model of a blockcipher is a well-known and widely-used model dating back to Shannon [24] and has seen frequent use in proving the security of various cryptographi...
Abstract. We introduce Verifiable Signature Sharing (VCS), a cryptographic primitive for protecting digital signatures. VCS enables the holder of a digitally signed document, who m...
