Towards Forward Security Properties for PEKS and IBE
Get PDFpeer reviewedIn cryptography, forward secrecy is a well-known property
for key agreement protocols. It ensures that a session key will remain
private even if one of the long-term secret keys is compromised in the
future. In this paper, we investigate some forward security properties
for Public-key Encryption with Keyword Search (PEKS) schemes, which
allow a client to store encrypted data and delegate search operations to
a server. The proposed properties guarantee that the client’s privacy is
protected to the maximum extent even if his private key is compromised
in the future. Motivated by the generic transformation from anonymous
Identity-Based Encryption (IBE) to PEKS, we correspondingly propose
some forward security properties for IBE, in which case we assume the
attacker learns the master secret key. We then study several existing
PEKS and IBE schemes, including a PEKS scheme by Nishioka, an
IBE scheme by Boneh, Raghunathan and Segev, and an IBE scheme
by Arriaga, Tang and Ryan. Our analysis indicates that the proposed
forward security properties can be achieved by some of these schemes if
the attacker is RO-non-adaptive (the attacker does not define its distributions
based on the random oracle). Finally, we propose the concept
of correlated-input indistinguishable hash function and show how to extend
the Boyen-Waters anonymous IBE scheme to achieve the forward
security properties against adaptive attackers.BRAID

Tmarus spicatus Tang & Li, 2009, sp. nov.
No full textTmarus spicatus sp. nov. Figs 12 A–C, 13 A–B Etymology. The specific name comes from the Latin adjective spicatus and means spike like, refers to the shape of the epigynal ridge. Diagnosis. This new species is similar to T. taiwanus Ono, 1977, but can be separated from the latter by: 1) the shape of the epigynal ridge, 2) the copulatory ducts long and twisted complicated vs. short and simple curved in T. taiwanus. Description. Female (holotype): Total length 5.50. Prosoma length 2.10, width 2.10; opisthosoma length 3.30, width 2.20. Prosoma brown with some grayish white stripes. Chelicerae, gnathocoxae, labium and sternum yellow. Eye measurements: AME 0.06; ALE 0.13; PME 0.08; PLE 0.11; AME–AME 0.20; AME– ALE 0.20; PME–PME 0.30; PME–PLE 0.40. MOA length 0.38 with front width 0.32 and back width 0.46, Legs yellow. Leg formula: 1243; leg measurements: I: 9.00 (2.70, 3.50, 1.80, 1.00); II: 9.10 (2.80, 3.50, 1.80, 1.00); III: 4.90 (1.50, 2.00, 0.80, 0.60); IV: 5.10 (1.70, 2.00, 0.80, 0.60). Opisthosoma dorsum grayish white with grayish black spots, also with 3 pairs of grayish black stripes posteriorly, venter gray. Epigynum (Figs 12 B–C, 13 A–B). Epigynum with a long longitudinal epigynal ridge, copulatory openings located bilaterally in the posterior of ridge, copulatory ducts long, flat and twisted, spermathecae small. Male: Unknown.
