Cryptographic system of symmetric-key encryption using large permutation vector keys

A non-transitory computer-readable medium having computer-executable instructions stored thereon for encrypting a block of data, said instructions, when executed by a computer, causing the computer to perform a method comprising:

• defining a set of byte codes, said defining comprising:
• defining one or more user byte codes, said user byte codes being representative of the block of data;
• defining one or more meta byte codes, said meta byte codes each indicating that a reversible operation is to be performed during the encryption of the data as an additional step for strengthening the encryption;
• and
• defining one or more dead byte codes, said dead byte codes being excluded from representing the block of data and from indicating that the reversible operation is to be performed;
• defining a transformation vector from the set of byte codes, said transformation vector including one of each of the user byte codes, the meta byte codes, and the dead byte codes arranged in a random order;
• transforming the block of data, said transforming comprising:
• translating values of the user byte codes from the block of data across the transformation vector;
• randomly selecting one or more meta byte codes from the defined meta byte codes;
• performing the reversible operations indicated by the selected meta byte codes during translation of the values of the user byte codes from the block of data;
• translating values of the selected meta byte codes across the transformation vector;
• inserting the translated values of user byte codes into an encrypted block of data;
• and
• inserting translated values of the selected meta byte codes into the encrypted block of data.

A method of decrypting data, comprising:

• receiving, by a computer, a block of data to be decrypted, said data having been previously encrypted;
• storing, in a memory, a set of byte codes associated with the block of data to be decrypted, said set of byte codes having been used to encrypt the block of data to be decrypted;
• defining one or more user byte codes of the set of byte codes, said user byte codes being representative of the block of data to be decrypted;
• defining one or more meta byte codes of the set of byte codes, said meta byte codes each indicating that a reversible operation is to be performed during the decryption of the block of data as an additional step to be reversed from the encryption of the data;
• and
• defining one or more dead byte codes of the set of byte codes, said dead byte codes being excluded from representing the data to be decrypted and from indicating that the reversible operation is to be performed;
• storing, a transformation vector defined from the set of byte codes in the memory, said transformation vector including one of each of the user byte codes, the meta byte codes, and the dead byte codes arranged in a random order, said transformation vector having been used to encrypt the block of data to be decrypted;
• retrieving, by the computer, the transformation vector from the memory;
• transforming, by the computer, the block of data, said transforming comprising:
• translating values of the user byte codes from the block of data across the transformation vector, said translating reversing a translation of the user byte codes during encryption;
• translating values of the meta byte codes from the block of data across the transformation vector, said translating reversing a translation of the meta byte codes during encryption;
• performing the reversible operation indicated by the meta byte codes;
• and
• inserting the translated values of the user byte codes into a decrypted block of data.
