Authentication Using Piggy Bank Approach to Secure Double-Lock Cryptography
This addresses security vulnerabilities in cryptographic protocols for applications requiring secure communication, but appears incremental as it builds on existing double-lock and piggy bank concepts.
The paper tackles the problem of man-in-the-middle attacks in double-lock cryptography by introducing a piggy bank approach for authentication, resulting in a method called double-signature double lock cryptography that extends beyond hash-based message authentication.
The piggy bank idea allows one-way encryption of information that can be accessed only by authorized parties. Here we show how the piggy bank idea can be used to authenticate parties to counter man-in-the-middle (MIM) attack that can jeopardize the double-lock cryptography protocol. We call this method double-signature double lock cryptography and it can be implemented in ways that go beyond hash-based message authentication.
