Nt1310 Unit 3 Assignment 1 Gp

1) GlobalSetup(k): Taking a security parameter K as an data or the input, this capacity creates a worldwide parameter GP.
Input: Security Parameter K
Output: Generates a global parameter GP.This means it is applicable only for the the authorized users.
2) KeyGenSer(GP): Taking GP as an data or the input, this algorithm generates a private and public key combine (skS,pkS) for the data/information server.
Input:GP as the input means for the authorized user.
Output:Generates Data server key pairs(sks,pks).
3) KeyGenRec(GP): Taking a worldwide parameter GP as an information,this capacity creates a private and public key match(skR,pkR) for the recipient.
Input: GP as the input means for the authorized users.
Output:Generates receivers key pair(skr,pkr).
Input: GP as the input.
Output: Generates a public and private key for the time server.
5) dPECK(GP,pkS,pkRi,skRi,W): Taking GP,pkS,pkRi,skRi and a keyword set w=(w1,.wl) as the data source, the capacity gives back a ciphertext c1 of w for Ri.
Input:It will take GP,pkS,pkRi,skRi,W as the input and selects a keyword W=W1…Wn.
Output:Ciphertext c1(W) for Ri.
6) Trapdoor(GP,pkS,skRi,Q): Taking GP,pkS,pkRi and a keyword queries for Q=(w1,.wm),m<=las the source of information ,it yields a trapdoor TQ, 1 for Q produced by Ri.
Input:It will take GP,pkS,skRi, and a keyword query Q as input.
Output: A trapdoor T for Q generated by Ri..
7)Test(GP,TQ,1,skS,c1): Taking GP,TQ,1,skS and a cipherText cl of was the data sources,the capacity returns “1” if w incorporates Q and “0”
