DS1207 产品详情

FEATURES
• Cannot be deciphered by reverse engineering
• Time allotment from one day to 512 days for trial
periods, rentals, and leasing
• Partitioned memory thwarts pirating
• User-insertable packaging allows personal
possession
• Exclusive blank keys on request
• Appropriate identification can be made with a 64-bit
reprogrammable memory
• Unreadable 64-bit match code virtually prevents
discovery by exhaustive search with over 1019
possibilities
• Random data generation on incorrect match codes
obscures real accesses
• 384 bits of secure read/write memory create
additional barriers by permitting data changes as
often as needed
• Rapid erasure of identification, security match code
and secure read/write memory can occur if tampering
is detected
• Durable and rugged
• Applications include software authorization, gray
market software protection, proprietary data, financial
transactions, secure personnel areas, and system
access control
