When a clone device is recovered, the \"trace\" component detects the pirate users that have compromised the secret keys in their devices and participated in the construction of the clone device. The \"revoke\" component excludes the pirate users from accessing the future content. The state-of-art trace-revoke scheme is the very efficient subset difference based NNL scheme [11] which is also deployed in AACS [1], the industry new content protection standard for high definition DVDs. While its revocation and tracing are both very efficient, as pointed out by Kiayias and Pehlivanoglu from Crypto 2007, in its deployment NNL scheme may suffer from a new attack called pirate evolution attack . In this attack attackers reveal the compromised secret keys to the clone decoder very slowly through a number of generations of pirate decoders that will take long time to disable them all. They showed in a system with N users, the attacker can produce up to t *logN generations of pirate decoders given t sets of keys. In AACS context, that means a pirate can produce more than 300 generations of decoders by compromising only 10 devices. If this happens, it will indeed be a nightmare. \u0000 \u0000In this paper we are interested in practical solutions that can defend well against the pirate evolution attack in practice. In particular we devise an easy and efficient approach for the subset difference based NNL scheme [11] to defend well against the potential pirate evolution attack. Indeed it takes as small as 2 generations to detect and disable a traitor in a coalition. This can be achieved by only negligibly increasing the cipher text header size in an application like AACS. The simplicity, efficiency and practicality of our approach has made AACS to adopt it to defend against the pirate evolution attack.","PeriodicalId":53552,"journal":{"name":"International Journal of Applied Cryptography","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78354474","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We design a threephase bit optimalPSMT protocol tolerating mobile adversary, whose communication complexity matches the existing lower bound on the communication complexity of any multi phase PSMT protocol, tolerating mobile adversary. This significantly reduces the phase complexity of the existing O(t) phase bit optimal PSMT protocol tolerating mobile adversary, where tdenotes the number of nodes corrupted by the mobile adversary. Furthermore, we design a three phase bit optimalPRMT protocol which achieves reliability with constant factoroverhead against a mobile adversary. These are the firstever constant phase bit optimalPRMT and PSMT protocols against mobile Byzantine adversary. We also characterize PSMT protocols in directednetworks tolerating mobile adversary. Finally, we derive tight bound on the number of rounds required to achieve reliable communication from S to R tolerating a mobile adversary with arbitrary roaming speed.Finally, we show how our constant phase PRMT and PSMT protocols can be adapted to design round optimaland bit optimalPRMT and PSMT protocols, provided the network is given as collection of vertex disjoint paths.","PeriodicalId":53552,"journal":{"name":"International Journal of Applied Cryptography","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2008-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73332671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Each protocol in the stack, realizes a corresponding 'layer' model, over the 'lower layer'. We define layers, protocols and related concepts. We then prove the fundamental lemma of layering. The lemma shows that given a stack of protocols {πi}i=1u, s.t. for every i ∈ {1,...u}, protocol πi realizes layer Li over layer Li-1, then the entire stack can be composed to a single protocol πu||...||1, which realizes layer Lu over layer L0. \u0000 \u0000The fundamental lemma of layering allows precise specification, design and analysis of each layer independently, and combining the results to ensure properties of the complete system. This is especially useful when considering (computationally-bounded) adversarial environments, as for security and cryptographic protocols. \u0000 \u0000Our specifications are based on games, following many works in applied cryptography. This differs from existing frameworks allowing compositions of cryptographic protocols, which are based on simulatability of ideal functionality.","PeriodicalId":53552,"journal":{"name":"International Journal of Applied Cryptography","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2008-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85357434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
