EncryptBTreeWildcardFuzzySearchableIndex(BSI_WC, ).

Input: B⁺ tree fuzzy searchable index

    - user’s public key

Output: Encrypted BTree WildCard Fuzzy searchable Index

(1) Declare integer variables key1 and public1

(2) Assign key1 =

(3) Assign public1 =

(4) Find the number of elements “Enum” in

(5) For to Enum do

    / Encrypt the fuzzy keyword present in each node /

(6)      = [] mod key1

(7)  end for // loop

(8)  return Encrypted
