Message authentication

In this paper, we propose a geographically lightweight secure routing protocol (LS-TPGF) in a wireless multimedia sensor network (WMSN) using Cyclic Redundancy Check (CRC) and Elliptic Curve Cryptography (ECC) for node and message authentication.

The paper proposes a type of block cipher algorithm based on cryptographic hash function and public key cryptography. The algorithm proposed here is capable of verifying the origin and integrity of the encrypted message. On the other hand, establishing a shared secret key between the sender/encryptor and the receiver/decryptor can be done for each message separately.

The paper proposes a method for constructing block cipher schemes that enable verifying the source and integrity of the encrypted message. Additionally, the shared secret key between the sender/encryptor and the receiver/decryptor for each encrypted message is established based on the mechanism of public key cryptography.

This paper presents a lightweight digital signature-based routing message and node authentication solution for wireless multimedia sensor networks (WMSNs). The lightweight geographical security routing protocol (ECDSA-TPGF) is proposed on the basis of improving the original two-phase greedy geographical forwarding protocol (TPGF), in which we have added the solution Elliptic curve cryptography (ECC) and cyclic redundancy check (CRC) to create a digital signature for a sensor node attached to a routing message.

The article proposes a public-key cryptographic scheme based on the ElGamal algorithm. This scheme can perform security functions and authenticate the origin and integrity of the encrypted message simultaneously. Moreover, the proposed scheme is also used as the basis for developing an algorithm to establish a shared secret key for symmetric key cryptosystems.

In ordinary signature schemes, such as RSA, DSA, ECDSA, the signing process is performed only for a single message. Due to performance issues, in some contexts, the above solutions will become unsuitable if a party needs to sign multiple messages simultaneously. For example, in the authenticated key exchange protocols based on signatures between client and server, the server is expected to handle multiple key exchange requests from different clients simultaneously.
