Cryptographic Specifications

Parameter Specification
Encryption Type Symmetric
Encryption Method One-Time Pad (OTP)
OTP Generation Prime Numbers and True Random Number Generator (TRNG)
Key Architecture Shared-key
Key Generation Automated
Key Distribution Controlled / Directed
Key Management Automated
Authorized Distribution Family/Group and directed STIKABA distribution

STIKABA allows encryption keys to be shared between the encrypting STIKABA and specifically authorized decrypting STIKABAs. Directed distribution provides “Eyes Only” capability by allowing the originator to designate the STIKABA devices authorized to use the required key material.

Operation Levels

STIKABA incorporates five scalable Operation Levels designed to accommodate requirements ranging from individual data protection through enterprise-wide encryption management.

Operation Level Encryption Inventory* Families Groups per Family
Personal 50 1 1
Associate 100 2 2
Partner 150 7 15
Enterprise 200 31 45
Director 250 60 64

STIKABA ships from the factory at the Personal Operation Level. Higher Operation Levels may be activated through the STIKABA Dashboard and the SyferSafe Upgrade service.

Each successive upgrade adds encryption inventory and increases the Family/Group capacity available for organizing key distribution and encrypted communications.

Operation Level upgrades are permanent. A STIKABA cannot be downgraded.
