Iam working in searching encrypted files and retrieve data from it. I represented keywords in files in bloom filter structure using specific algorithm and also represent keywords I search for in bloom filter using the same algorithm . but I want to encrypt this bloom filters and search in it . and also encrypt the bloom filter that I search for . I want help in how encrypt and what is the mechanism used to compare this encrypted bloom filters in this encrypted form.
Good start may be to look at Java security at: https://docs.oracle.com/javase/8/docs/technotes/guides/security/SecurityToolsSummary.html
and http://docs.oracle.com/javase/7/docs/technotes/tools/#security
I guess, it is a problem of SHA-2. So, convert input to SHA-2 and add it to filter.
