Transitive Signature Schemes - Micali, Rivest (2002) (12 citations) (Correct)
....The problem of nding a directed transitive signature scheme remains a very interesting open problem. We have not been able to make much progress on this problem. We note that there is some similarity between our problem and the problem of atomic proxy cryptography due to Blaze et al.[2]. However, we Transitive Signature Schemes 9 have not been able to come up with a provably secure undirected transitive signature scheme for a scheme modelled on their ideas without losing too much eciency in the proof. Another interesting open problem is the following: Given Alice s signature on ....

Secure Personalization Using Proxy Cryptography - Girard (Correct)
....This means that if there exist two proxy keys A B and B C everyone can compute a third proxy key A C . Proxy cryptosystems have been introduced for signatures in [4] and extended in [5] to specific ciphertexts. Blaze and Strauss generalized proxy encryption and classified proxy schemes in [1, 2]. They give an atomic proxy function for an ElGamal based cryptosysytem, called cryptosystem , and note that the original ElGamal cryptosystem could have been used as well. In the next section we recall the cryptosystem and the associated proxy function. 1.4.2 Cryptosystem To generate a key ....

On Quorum Controlled Asymmetric Proxy Re-encryption - Jakobsson (1999) (7 citations) (Correct)
....an increasing need for a flexible infrastrucure, we foresee the need for many new secure and flexible primitives extending the basic communication and encryption capabilities available today. One such primitive is proxy re encryption, which was recently introduced by Blaze, Bleumer and Strauss [2]. Proxy re encryption is a translation between ciphertexts from one encryption key to another encryption key. It can be used to forward encrypted messages without having to expose the cleartexts to the participants involved, a primitive with many potential commercial uses. In symmetric proxy ....
....to know a function of the secret keys associated with both the incoming and outgoing transcripts. The proxy needs to be trusted not to collude with one of the participants holding these secret keys, or the other secret key can be derived. This characterization has the same meaning as that of [2], in which no trust has to be placed in the proxy, but the two other participants need to trust each other. On the other hand, in asymmetric proxy re encryption, it is not necessary for the proxy to any function of the secret key corresponding to the produced ciphertext, which is advantageous ....

Signature Scheme for Controlled Environments - Viswanathan, Boyd, Dawson (1999) (Correct)
....x 1 0 ; x2 ) CreateP roxy(x1) Fig. 2. Conceptual representation of proxy joint signature system In the subsequent analysis, the proxy is assumed to be reliable and will not collude with the attacker. This is a valid assumption because the proxy signer should be unconditionally trusted [1] by the signer before delegating the power. The CreateP roxy function (adopted from the proposal by Mambo et al. 18] can be analysed as a HoP signature on a unity message , m = 1 mod q (see scheme EG I.4 in [13] The HoP signature generation equation is s = mx kr mod q, where s is the ....

Cryptography and the Internet - Bellovin (1998) (5 citations) (Correct)
....on the inside host. There are no good solutions for this problem. Presumably, some sort of keysharing with the firewall must take place. Again, that demands strong verification of the firewall s right to the information. It may also demand multiparty key negotiation, or perhaps proxy cryptography [BBS98]. 6 Protocol Verification It should come as no surprise that the cryptographic protocols and mechanisms used in the Internet are in need of verification. They are complex, and as we all know, it is very easy to make mistakes in designing even simple cryptographic protocols. But the analysis here ....
