(mathcal A ) can query the trapdoor generation oracle Trapdoor ((sk, cdot )) to obtain the trapdoors corresponding to keywords (w in {0,1}^*) of his choice.
It returns the challenge (langle C^, T^_w rangle ) to (mathcal A.) (mathcal A ) can query the trapdoor generation oracle Trapdoor ((sk, cdot )) to obtain the trapdoors corresponding to keywords (w in {0,1}^*) of his choice.
Thus, GO terms corresponding to keywords describing the disease were retrieved from AMIGO DB; genes annotated with selected GO terms were retrieved from Entrez-Gene at NCBI as well as all gene annotations.
Taken as input the system global parameter GP, the keyword secure index I w, the trapdoor T w corresponding to keyword w, the attribute set Ψ i of user U i and the access structure, this algorithm will output 1 if Ψ i satisfies and the trapdoor T w matches I w.
Human Protein Atlas proteins corresponding to keyword "Prostate"; protein class "Candidate cancer biomarkers"; HPA evidence "High", and filtered for IHC staining in PCa, when interfaced with the MS datasets gave a set of 12 proteins common to both lists (Additional file 6).
In parallel, we screened non-English journals, using Japanese, Chinese, French, German, Italian, Spanish, and Turkish keywords corresponding to the keywords in A-E (details shown in the legend to Figure 1).
To this aim, an expert of the studied disease has to carefully (i) extract from her knowledge and from OMIM the phenotypes which characterize the disease, (ii) associate keywords to these phenotypes and (iii) retrieve the most relevant GO terms corresponding to these keywords.
(mathcal A ) can adaptively query the trapdoor oracle ({mathsf {Trapdoor}} (sk_S,cdot )) to obtain the trapdoor corresponding to any keyword (w in {0,1}^*) of his choice.
(mathcal A ) can query the trapdoor generation oracle Trapdoor ((sk_R, cdot )) to obtain the trapdoor corresponding to any keyword (w in {0,1}^*) of his choice.
