TL;DR: A symmetric (shared key) key encryption scheme as mentioned in this paper uses an irreversible function and a random initial message to obscure the key from cryptographic analysis, resulting in a system with a high level of data confidentiality at the same time as low resource utilisation and high speed operation.

Abstract: A symmetric (shared key) key encryption system which encodes message data using an algorithm, a secret key(1) and a random initial message(5) and a matching decryption system which decodes encrypted data using an algorithm and the same secret key(1). The system uses an irreversible function and a random initial message(5) to obscure the key(1) from cryptographic analysis, resulting in a system with a high level of data confidentiality at the same time as low resource utilisation and high speed operation. Confidentiality is further enhanced by the essentially linear relationship between key length and the product of resource utilisation and processing time per unit message data, allowing the system architect to select a longer key length without disproportionate increase in complexity or power consumption or decrease in speed.
