RSA Data Security tables US encryption standard
Tom Foremski RSA Data Security has proposed an encryption technology as a US government standard. The proposal is part of the US National Institute of Science and Technology’s (NIST) efforts to adopt a more powerful encryption technology called the Advanced Encryption Standard (AES). This is to replace the aging Data Encryption Standard (DES) which is now over twenty years old. Researchers at RSA say they have a new encryption algorithm using a 128bit key size compared with 64 bits for DES. “Our proposal builds on what we have learned over the past fifteen years to deliver the highest level of security with performance characteristics suitable for commercial deployment,” said Dr Rivest, a professor at MIT, and leading researcher for RSA. (The ‘R’ in the company name RSA comes from Dr Rivest’s surname). The NIST specifications call for a publicly defined, symmetric block cipher, designed so that key length may be increased as needed. Algorithms submitted to NIST will be judged on security, memory requirements, hardware and software compatibility, simplicity and licensing requirements.
