First flexible crypto-processor with adjustable security level

The new secure crypto processor where the security can be adjustable is developed by Yasuyuki Nogami with colleagues at Okayama University and Tokyo Electron Device ltd. It is supported by Japan Science and Technology Agency. It is flexible to adjust the level of security without upgrading the device. It supports many cryptographies like elliptic curve, pairing – based cryptography. Information security technology is necessary for Cloud and IoT applications. RSA cryptography and elliptic curve cryptography in public help users and devices for authentication. Secured applications like ID – based cryptography utilizes ID as the public function and time function encryption required complex cryptographies such as pairing – based cryptography. Computer functions improve drastically for which the security should be provided to prevent unauthorized users. It is a difficult task to adjust security function as public functions are based on mathematical problems. To give an example the secure key length of RSA cryptography increases 512, 1024, 2048, and then 3072 bits. Crypto processors are need to upgrade along with mathematical digitals. Yasuyuki Nogami and colleagues have developed a secure crypto processor with flexible adjustment. The device need not be upgraded. It supports cryptographies like elliptic curve and pairing – based cryptography. The secure cryptoproce...
