TECHNIQUES FOR KEY RATCHETING WITH MULTIPLE STEP SIZES

机译:具有多个步长大小的键破解技术

摘要

Techniques for key ratcheting with multiple step sizes are described. In one embodiment, an apparatus may comprise a messaging component operative to receive an encrypted message, the encrypted message encrypted according to a multi-dimensional ratcheting encryption scheme; determine a message iteration count for the encrypted message; and generate a decrypted message by decrypting the encrypted message based on a decryption key; and a key management component operative on the processor circuit to decompose the message iteration count into a plurality of message chain key iteration counts; and determine the decryption key based on the plurality of message chain key iteration counts. Other embodiments are described and claimed.
