We present a new identity based authenticated key agreement protocol from pairings satisfying the required security attributes. The security of our protocol is based on the bilinear Diffie-Hellman assumption.
Joux  presented a one round protocol for tripartitie key agreement and Al-Riyami et.al.  developed a number of tripartitie, one round, authenticated protocols related to MTI and MQV protocols. Recently, Boneh and Sil-verleg  studied multilinear forms, which provides a one round multi-party key agreement protocol. In this paper, we propose (n + 1)… (More)
Let G(x, y) and G D (x, y) be the Green functions of rotationally invariant symmetric α-stable process in R d and in an open set D respectively, where 0 < α < 2. The inequality G D (x, y)G D (y, z)/G D (x, z) ≤ c(G(x, y) + G(y, z)) is a very useful tool in studying (local) Schrödinger operators. When the above inequality is true with c = c(D) ∈ (0, ∞), then… (More)
Pose estimation, which determines the position and the attitude of the camera, is a prerequisite for a variety of photogram-metric tasks such as image matching, surface reconstruction, ortho-photo generation, and object recognition. As digital imagery is becoming more popular in photogrammetric applications, features other than points are increasingly… (More)
We study the decay of eigenfunctions of the non self-adjoint matrix operator H = −∆+µ+U W −W ∆−µ−U , for µ > 0, corresponding to eigenvalues in the strip −µ < ReE < µ.
This note is devoted to reveal the structure of signed fundamental solutions of a conservation law without the convexity assumption. It is assumed that the flux is in C 1 (R) and has a finite number of inflection points. Fundamental solutions of the case have been constructed in  employing convex and concave envelopes. This construction provides useful… (More)
Previously we showed that biodegradable nanoparticles containing poly-IC or CpG oligodeoxynucleotide (ODN) together with ovalbumin (OVA) were efficient at inducing MHC-restricted presentation of OVA peptides in dendritic cells. The CTL-inducing activities of the nanoparticles were examined in the present study. Nanoparticles containing poly-IC or CpG ODN… (More)
BACKGROUND Nanoparticles (NPs) prepared from biodegradable polymers, such as poly (D,L-lactic acid-co-glycolic acid) (PLGA), have been studied as vehicles for the delivery of antigens to phagocytes. This paper describes the preparation of antigen-loaded PLGA-NPs for efficient cross-priming. METHODS NPs containing a similar amount of ovalbumin (OVA) but… (More)
