Secret Public Key Protocols Revisited
[chapter]
2009
Lecture Notes in Computer Science
Preserved Fulltext
In this paper, we revisit the concept and introduce the notion of identity-based secret public keys. ...
We examine identity-based secret public key protocols and give informal security analyses, indicating that they are secure against off-line password guessing and other attacks. ...
Acknowledgements The authors would like to thank Qiang Tang for his very helpful feedback on an earlier draft of this paper, and Kim-Kwang Raymond Choo for pointing out a flaw in an earlier version of ...

We present a hierarchy of authentication and AEAD security notions, interpolating between the lowest level of protection (against forgeries) and the highest level (against forgeries, replays, reordering ...
The definitions in the literature and the constructions used in practice all protect against forgeries, but offer varying levels of protection against replays, reordering, and drops. ...
First, we construct a hierarchy of authentication levels: 1. protection against forgeries, 2. protection against forgeries and replays, 3. protection against forgeries, replays, and reordering of messages ...

This is rather cumbersome because homomorphic cryptosystems are known to be malleable and therefore not to be CCA secure. ...
Semantic security against chosen-ciphertext attacks (IND-CCA) is widely believed as the correct security level for public-key encryption scheme. ...

We examine identity-based secret public key protocols and give informal security analyses which show that they may well be secure against online password guessing and other attacks. ...
The majority of current security architectures for grid systems use public key infrastructure (PKI) to authenticate identities of grid members and to secure resource allocation to these members. ...
Since the encryption scheme is IND-ID-CCA secure, E only has a negligible success probability to find the correct aP. ...
