Abstract: A method for searching an encrypted file comprises: receiving a query from a first device of a set of devices; tokenizing the query; searching the encrypted file, without decrypting the file, for the tokenized query; aggregating results of the search; and outputting the aggregated results. The searching includes checking a bloom filter of an index of the encrypted file. The index includes a file public secret (R), a proof of work for the file secret (Rproof), a multipart threshold public encryption key (LKe-pub), a multipart threshold public search key (LKs-pub), and the bloom filter. The bloom filter including index values that are elliptic curve paired between a curve-hashed token of the encrypted file and the product of the encrypted file's ephemeral secret value (r) and the multipart threshold public search key (LKs-pub).
