ARRAYS: A New Encryption Scheme

Title: ARRAYS: A New Encryption Scheme

Research Question: Can ARRAYS, a new encryption scheme based on finite frames and Hadamard arrays, withstand chosen-plaintext attacks?

Methodology: The researchers proposed a cipher similar to the One Time Pad and McEliece ciphers. They used a subband coding scheme for encryption, with orthogonal frames created using Fourier frames or alternative methods. They then analyzed the robustness of their scheme against chosen-plaintext attacks.

Results: The researchers demonstrated that their cipher is vulnerable to a chosen-plaintext attack. This means that an attacker could potentially decipher the encrypted message by modifying the plaintext slightly and then re-encrypting it.

Implications: While the ARRAYS cipher has some desirable properties, such as randomness in the encryption process and a relatively small key size, its vulnerability to chosen-plaintext attacks makes it unsuitable for use in high-security applications. The researchers plan to further investigate the cipher's properties and potential improvements in future studies.
