4-15-96, W$U: "RSA Data May Be Sold in Stock Deal." Security Dynamics Technolgies, Inc. is in talks to buy closely held RSA Data Security Inc., the dominant supplier of privacy technology for the Internet, for stock valued at about $200 million. Industry executives said Security Dynamics may hope to combine its proprietary technology with standard encryption software from RSA, which could yield products that can be used with a broader array of computer products. Some of RSA's partners may be taken aback, since few are familiar with relatively obscure Security Dynamics. The largest single RSA shareholder is Addison Fischer, founder of a Florida security-products concern called Fischer International. FIX_rsa
