Validian's Secure Instant Messenger Now Available for Download; With Validian's Secure Instant Messenger, You Instantly Can Exchange Messages and Files Simply and in Total Security

Validian's SIM system offers the highest level of security available for real-time communication and file exchange. SIM creates "gated communities" of trusted users. It offers a real-time and fully secure system for collaboration between individuals and groups, including instant messaging, file exchange, synchronous and asynchronous collaboration, and enterprise-wide presence. All SIM participants are authenticated and messages and files of any size and of any type, including video and audio files, can be transferred with full security.

"SIM enables individuals and corporations to set-up interactive, distributed data exchange sessions with a degree of security and ease not otherwise available in the market today," said Dr. Andre Maisonneuve, President and Chief Executive Officer of Validian. "Bilateral and multilateral exchanges can take place between any number of individuals, and files of any size can be transferred in full security at the same time."

All messages are encrypted using a unique session key known only to the originator and the recipient, which ensures the authenticity of messages. Message content cannot be decrypted or altered by any source during transit.

No rogue user can penetrate SIM or send messages to any SIM community member. SIM users are protected from receiving SPAM messages from unauthorized sources. SIM users are uniquely identified in the SIM domain controller, and may authorize new users or deny users the possibility of communicating with them. SIM provides an audit trail of every exchange, which can be transferred to a secure archiving system. Installation of SIM can be monitored by the corporate network administrator to ensure compliance with corporate security policies.

SIM can reach people anywhere on the Internet, behind and across firewalls, and carries the highest level of security in all communications. SIM is ideal for corporations for whom the issue of security and speed of communication is paramount.

SIM can be implemented on a USB flash memory card, which makes it an ideal medium for the road warrior to keep in touch with his environment in full security. SIM USB users plug their USB flash memory card into any computer linked to the Internet and have instant access to all their IM contacts and archived exchanges. The USB memory cards can hold a large amount of files that can be exchanged securely with any other SIM user.

SIM operates over Validian's Application Security Infrastructure (ASI) and benefits from all the security features of the ASI infrastructure.

About ASI

Validian's ASI is a comprehensive integrated infrastructure for securing distributed applications and Web services. Based on open standards and a distributed architecture, ASI delivers a security level comparable to that of more expensive and complex PKI or VPN solutions, but with the ease of use, low cost, and dynamic scalability of SSL. ASI is specifically designed for distributed applications and distributed networks. It automatically manages all critical security functions between any applications, including authentication, encryption, key generation, key distribution, addressing, and data transport. ASI is completely network independent, supporting most major platforms, network architectures, transport protocols, and development environments. ASI guarantees the delivery of the messages and files to, and only to, the target destination, without offering any possibility of being intercepted at any point during its transit.
