Abstract
This paper presents a comparative evaluation of possible encryption algorithms for use in a self-contained, ultra-secure router-to-router communication system, first proposed by El Rifai and Verma. The original proposal utilizes a discrete logarithm-based encryption solution, which will be compared in this paper to RSA, AES, and ECC encryption algorithms. RSA certificates are widely used within the industry but require a trusted key generation and distribution architecture. AES and ECC provide advantages in key length, processing requirements, and storage space, also maintaining an arbitrarily high level of security. This paper modifies each of the four algorithms for use within the self-contained router-to-router environment system and then compares them in terms of features offered, storage space and data transmission needed, encryption/decryption efficiency, and key generation requirements.
Highlights
With the rise of globalization, microelectronics, and the information age, the need for rapid, long-distance transmission of unconditionally secure information has never been greater
The second, recently proposed unconditional cryptographic system is quantum cryptography, where security is achieved through the laws of quantum mechanics, which allow for very accurate determination of eavesdroppers along a quantum channel, as well as the simultaneous determination of small shared and secure random values
Elliptic Curve Cryptography (ECC), or AES encryption, since neither Alice nor Bob knows the other individual’s private key, it would be possible for a third-party external audit, given hardware access to both router keys and all traffic sent, to determine the sender of all encrypted data
Summary
With the rise of globalization, microelectronics, and the information age, the need for rapid, long-distance transmission of unconditionally secure information has never been greater. The first, the one-time pad, proposed by Gilbert Vernam in 1919 [1], utilizes a singleuse encryption key equal to the message length which both the sending and receiving parties may use to encrypt and decrypt the message. The disadvantages of this system in a long-term high data rate communication system are obvious, with each message requiring a preshared key equal to the message length. Each router pair would be factory-initialized with a shared secret, enabling direct secure communication between the two regardless of network distance or security, with shared transmitted data on each end decrypted and used as the basis of further secure key generation as necessary. This paper first examines the originally proposed discrete logarithm-based encryption system and proposes and compares other more commonly used encryption systems which may be used in this entirely selfcontained environment, including RSA, ECC, and AES based encryption
