4Kx16 Bits OTP (One-Time Programmable) IP, UMC 110 nm 1.2V/3.3V L110AE Process
Secure-IC's Securyzr™ Tunable Public Key Cryptographic (RSA, ECDSA, SM2, Diffie-Hellman) accelerator - optional SCA protection
This IP provides comprehensive RSA encryption / decryption / signature / verification functionalities with hardware acceleration for modular arithmetic operations.
The RSA IP is composed of two parts:
- The RSA Software library which is run on the host CPU. This CPU can be the main CPU or a dedicated CPU. Secure-IC is able to provide this dedicated CPU.
- The RSA Hardware accelerator and its dedicated RAM.
ECC is a public-key cryptosystem (the encryption key is public when the decryption key is private) based on the algebraic structure of elliptic curves over finite fields.
A benefit of using elliptic curve cryptography is a smaller key size than RSA-based system to provide the same level of security. For example, a 256-bit elliptic curve public key provides the same level of security than a 3072-bit RSA public key.
This IP provides secure ECC primitives such as signature/verification with ECDSA and SM2, with hardware acceleration for modular arithmetic operations.
