Abstract: This disclosure relates to method and system for providing a light weight secure communication for computing devices. In one example, the method includes generating a new encryption key based on a selected encryption key from among a plurality of encrypted keys and a current synchronized hash based on a set of pre-defined rules, generating an updated synchronized hash based on a message to be transmitted and the current synchronized hash using a pre-defined hash algorithm, encrypting the message to be transmitted using the new encryption key to generate an encrypted message, transmitting the encrypted message, and replacing the current synchronized hash with the updated synchronized hash. The set of pre-defined rules and the pre-defined hash algorithm are retrieved from a pre-installed library. Further, the current synchronized hash, the plurality of encryption keys, and the pre-installed library are synchronized between the first computing device and the second computing device.
