Encryption based on Conference Matrix
This addresses secure communication by proposing a new encryption method, but it appears incremental as it builds on existing matrix-based cryptography without broad SOTA claims.
The authors developed an encryption scheme using (-1, 1) conference matrices, achieving high security with a decryption key based on prime powers, and observed robustness against popular cipher attacks without compromising information security.
In this article, an encryption scheme based on (-1, 1) conference matrix has been developed. The decryption key comprising of fixed number of positive integers with prime power yields the high level security of message. Some popular attacks has been discussed in the context of cryptoanalysis and observed that it is robust against the popular cipher attack and the security of the information does not compromise.
