• We propose a length-preserving enciphering scheme that achieves PRP security and streamable decryption. No enciphering scheme satisfying these properties is known. Our enciphering scheme is suitable for secure communication on narrowband channels and memory-constrained devices. Although length-preserving enciphering schemes satisfying the SPRP security, which is stronger than the PRP security, are known, it is impossible to support the SPRP security and the streamability at the same time. Namely, the memory to store an entire plaintext/ciphertext is required. When the decryption is performed with memory-constrained devices, the PRP security is the strongest concept of achievable security.
