Systems and methods for multi-function and multi-purpose cryptography

摘要

Systems and methods for multi-function and multi-purpose cryptography are described, including obtaining a message to be encrypted by a cipher engine configured to perform encryption using a plurality of predetermined tags with an encryption function; determining a tag of the plurality of predetermined tags based on the message; encrypting, by the cipher engine, the message using the tag to produce a ciphertext; and sending the ciphertext.

主权项

1. A computer-implemented method, comprising, by at least one hardware processor:
obtaining a message to be encrypted by a cipher engine; identifying a tag corresponding to the message; retrieving length information, based on the identified tag, from tag information that comprises a plurality of associations, wherein each of the plurality of associations comprises an association between the tag and length information, and wherein the length information comprises one or both of an encryption length and an integrity length; encrypting, by the at least one hardware process executing the cipher engine, the message using the identified tag and the retrieved length information to produce a ciphertext; and sending the ciphertext.
