IEEE 1667 - The IEEE 1667 Password Silo

The IEEE 1667 Password Silo

Each device must have at least one ACT with at least one Authentication Silo

The Password Silo is an Authentication Silo initially developed to the External IEEE 1667 Silo guidelines

Password functionality includes

• Password storage with protected media access

• Single Password or Dual Password usage

• Device User and Device Administrator roles

• Authenticated command sequences to

• • Create, validate and remove passwords

• • Lock and unlock media access

• Command sequences for a silo to

• • Report silo cryptographic capabilities

• • Report silo status

• • A Mutual Challenge Handshake Authentication Protocol sequence

This silo uses simple cryptography:

• HASH algorithms (SHA)

• Random Number Generators
