2. 2  A single electronic credential which:  Can be used and accepted across multiple organizations  Allows legally binding electronic signatures to be made in countries around the world  Is easy and straightforward for the user to employ  Can be obtained from a SAFE-accredited source of the user’s choice  Vendors will have the opportunity to pursue SAFE-accreditation  No single supplier controls the marketplace  A set of open standards covering:  Software that can make, and validate (check), electronic (digital) signatures meeting SAFE business rules  Ultimately, this capability built in to off-the-shelf products  A trust-based, collaborative community of biopharmaceutical companies and their business/regulatory partners efficiently using electronic processes to conduct business transactions SAFE Goals

3. 3 What Technology Does the SAFE Credential Employ? Public Key Technology  Widely used for secure electronic and internet transactions today  Based on two keys (large numbers), mathematically linked  One key is kept private, the other is made public  Public key appears in a digital certificate – an electronic credential (file) that links the public key to a person’s identity  Private key is kept secret on a hardware device (like a smartcard)  To make a digital signature, the user of the hardware device inserts it into the PC and proves his or her identity to the device (usually done with a passphrase that only the user and the device knows).  The private key on the device then makes the digital signature on the document selected by the user.  To validate (check) a digital signature, commercially available software uses the public key from the digital certificate What Technology Does the SAFE Credential Employ?

4. 4 3. Present information (message) to be signed to the user (signer) Subscriber 1.Authenticate [best practice] 2.Select information to be signed 5. Acknowledge the signature parameters (request for biometric/passphrase/password and legally binding message) SAFE Transaction Meaning of signing: Approved Certificate 4. Select Signature parameters 6. Create the digital signature (preserves document integrity) 7.

6. 6  A special server called a Certification Authority (CA)  Analogy: the machine at the Department of Motor Vehicles which creates your driver’s license  But only after you have proven your identity to a Registration Authority (RA)  Analogy: the window at the DMV where you prove who you are before you can get your driver’s license  An “Issuer” is a vendor, bank, or company that operates a CA and an RA, and issues/supplies credentials to users  SAFE will accredit Issuers so that users wishing to get SAFE credentials (digital certificates) can trust who supplies them Who Issues SAFE Credentials?

8. 8 Individual Trust Domains Pharma X Biopharma Y FDA EMEA = = = Syndicated Bank Trust Network Regulated Financial Institutions Issuers Pharma Outsourced Identity Credential Provisioning = BioPharma Industry Trust “Bridge” Any SAFE Accredited CA = = = j The Solution: SAFE Trust Bridge

9. 9  Two possibilities:  Your organization has its own internal or out-sourced CA which can be cross-certified with the SAFE Bridge CA  Your CA issues your employees SAFE-compliant credentials (certificates) which can then be accepted by other SAFE Members using the SAFE Bridge CA  You purchase a SAFE credential (certificate) from a SAFE-accredited Issuer that is cross-certified with the SAFE Bridge  Either way, your credential is interoperable and accepted within the SAFE community How Does a User Get a SAFE Credential?

10. 10  A CA which establishes “trust connections” among other CAs  Issues certificates to SAFE “Member” CAs  Accepts certificates issued to it by SAFE “Member” CAs  (Analogy: mechanism to permit one DMV to trust drivers’ licenses issued by another DMV – electronically)  Is NOT a “root of trust” – rather, just a conduit of trust  Employs a distributed - NOT a hierarchical – model  Thus, all members are treated as equals  Is product-neutral – employs open standards for certificate issuance and management  Will support digitally signed transactions among Members, and between Members and regulators What is a Bridge Certification Authority?

11. 11  No – in fact, there is one already in operation (the U.S. Federal Bridge CA) and several others in the planning stages  What is needed is:  A Certification Authority  Policy foundation  Certificate Policy per RFC 2527/3647  Certification Practices Statement per above  Hardware  Server running CA software  Server running directory/data base software  Server running software to respond to inquiries on certificate status  A governing body (typically called a Policy Authority)  An operational body that actually runs it (typically called an Operational Authority) Is it Hard to Establish a Bridge CA?

12. 12  One hardware device per person, which holds your digital identity (this identity cannot be copied)  Ability to make your electronic (“digital”) signature on a document or transaction, meeting SAFE rules so it is legally binding  Ability of any SAFE Member to check (“verify”) your signature What does SAFE Mean to Users?

13. 13  There is plenty of software currently available which performs and validates digital signatures. Two examples (there are many others):  Adobe 6.0  Microsoft Office XP/2003  We are releasing standards for SAFE-compliant signing and validation software  We encourage vendors to adjust their products to meet these standards  In most cases, doing so should not require substantial changes to existing products For Vendors
