Cryptanalysis of a Verifiably Committed Signature Scheme Based on GPS and RSAany partial signature, the attacker can extract the corresponding full signature. The attack works provided the attacker previously obtained a full signature of a special form, which can be done simply by eavesdropping a very small number of full signatures. For example, with the originally recommen

RSA Accumulator Based Broadcast Encryptionset of privileged users can decrypt it. In this paper, we analyze how RSA accumulators can be used as a tool in this area. First, we describe a technique for achieving full key derivability given any broadcast encryption scheme in the general subset-cover framework [16]. Second, we show that Asano’s

As few as about 2. known plaintexts and related-key known ciphertexts in the first case, and 2. chosen ciphertexts in the second case are required to mount key-recovery attacks. These results show that seemingly academic attacks seriously need to be taken into consideration when i

Evaluating the Impact of Intrusion Detection Deficiencies on the Cost-Effectiveness of Attack Recoveiciencies. ITDB, a Intrusion Tolerant Database prototype system, has been proposed, which can detect intrusions, repair the damage caused by intrusions in a timely manner. In this paper, we evaluate ITDB using TPC-C benchmark. The performance measurements show that ITDB system is cost-effective with

A Model for the Semantics of Attack Signatures in Misuse Detection Systemsodeling and specification of attack signatures. A couple of languages are proposed in the literature, which differ in the aspects of signatures that can be described. Some aspects that can be specified in one language cannot be expressed in another. In this paper we present a model for the semantics
