Latest Patents

Dongyoung Roh's latest inventions include:

1. **Apparatus and method for providing Feistel-based variable length block cipher** - This invention introduces a novel approach to encryption, where plaintext of a certain bit length is transformed into ciphertext of the same length. The apparatus features an encryption/decryption key generation unit that produces multiple keys based on a secret key and the length of the data, ensuring robust data protection. Additionally, it includes a tweak generation unit that supports the encryption process, maintaining the length consistency between plaintext and ciphertext, which is vital for various applications in secure communications.

2. **Apparatus and method for converting random binary sequence into random integer** - This invention addresses the need for generating random integers from binary sequences. It not only converts random binary sequences into integers but also checks if the output falls within a defined interval. In cases where the output does not meet that criterion, the method intelligently updates the binary sequence to generate uniformly distributed random integers, thereby enhancing the reliability of random number generation essential for cryptographic applications.
