Method and system for securing electronic data

A system for securing electronic data, said system comprising a writer module and a reader module, wherein said writer module is configured to encrypt the electronic data through a symmetric key encryption thereby generating a secured data file format for the encrypted electronic data, said writer module further configured to:

• create a data file signature;
• add a Gateway Header Block (GHB), said GHB configured to communicate with a server and compute a first key, wherein the information for computing the first key comprises at least one of IP address, name of the server, port numbers, and protocols;
• encrypt the GHB using a fixed key and a standard encryption algorithm;
• create a file icon block and an open header block;
• create a first data record block with a file policy and information for computing a second key;
• create a second data record block with an adapter data and information for computing a third key;
• compute a third key;
• create a first random data block and a file data block;
• create a first encrypted block by encrypting the file data block with the third key and a standard encryption algorithm;
• create a second random data block;
• create the second encrypted block by encrypting the second data record block, first random data block, first encrypted block and the second random data block, with the second key and the standard encryption algorithm;
• and
• create the third encrypted block by encrypting the first data record block and the second encrypted block with the first key and the standard encryption algorithm;
• and
• wherein the reader module is configured to receive the secured data file comprising the encrypted data, and decrypt the encrypted electronic data through symmetric key decryption, said reader module further configured to:
• decrypt GHB using the fixed key;
• compute the first key using the information for computing the first key in GHB;
• decrypt the third encrypted block using the first key and extract the file usage policy from the first data record block;
• compute the second key using information in the first data record block;
• decrypt the second encrypted block using the second key;
• discard the second random data block;
• compute the third key using the information in the second data record block and extract the adapter data;
• decrypt the first encrypted block using the third key;
• discard the first random data block;
• and
• extract the electronic data from the secured data file.
