Microsoft Corp and Security Dynamics Technologies Inc signed a number of cross-licensing agreements on security technology giving Microsoft greater access to encryption and authentication token technology developed by Security Dynamics and its RSA Data Security Inc subsidiary: these include new licensing rights to software for supporting Security Dynamics’ SecurID token technology in future Microsoft products. The pacts would enable corporate users to increase security through the addition of SecurID token authentication to the Windows NT Server network operating system and Microsoft Internet Information Server. Developers’ toolkits from RSA will be available which feature Microsoft’s cryptographic programming interfaces, CryptoAPI, enabling the addition of secure features to software products in development. RSA will receive ongoing revenue from Microsoft based on the use of patented RSA technology. Microsoft will license CryptoAPI to RSA, including rights to incorporate CryptoAPI into RSA’s BSAFE and other security toolkit products, to put CryptoAPI up on new systems, and to build on Microsoft’s base set of cryptography services. Similar agreements were struck convering Security Dynamics software, the company said.
