How to build evidence in a public-key infrastructure for multi-domain environments,act that one of the most recurrent motivation by papers advocating the necessity of a PEI, is to support electronic commerce, all the new proposals of PKIs do not define any procedure to specify which evidence must be collected and in which form, when users carry out a commercial transaction..We thi

Open key exchange: How to defeat dictionary attacks without encrypting public keys,ficult to memorize for humans. Bellovin and Merritt [4] proposed “encrypted key exchange” (EKE) protocols, to frustrate key-guessing attacks. EKE requires the use of asymmetric cryptosystems and is based on encrypting the public key, using a symmetric cipher..In this paper, a novel way of key exchan

Protocol interactions and the chosen protocol attack,iscuss such interactions between protocols, and present a new attack, called the chosen protocol attack, in which an attacker may write a new protocol using the same key material as a target protocol, which is individually very strong, but which interacts with the target protocol in a security-relev

How to convert any digital signature scheme into a group signature scheme,how, how any digital signature scheme can be converted into a group signature scheme. This solves an open problem posed by Chaum and van Heijst. To obtain this result, the encrypted identity of the signer is signed together with the message. The correctness of the encryption is ensured by an . that
