Data Encryption Cryptoprocessing IP Cores for Secure Encoding and Decoding
CAST's experience with encryption IP cores for security applications spans more than a decade and close to a hundred customers.
The cores we provide offer a security solution that fits your application at an affordable price, especially in the areas of Internet Protocol Security, secure data storage, and secure data exchange.
We provide state-of-the-art cores for the current encryption standard — AES — and for other popular techniques and methods including DES, Triple DES, MD5, and SHA.
We source our cores from Technology Partners Ocean Logic and SoC Solutions, who share our total dedication to customer success.
