FIPS 140-3 DSC Token in India: What You Need to Know Before 21 September 2026
If you use a Digital Signature Certificate (DSC) for GST, Income Tax, MCA filings, e-Tendering or other government services, there is an important change you should know about in 2026: the Indian PKI ecosystem is moving toward FIPS 140-3 Level 3 certified cryptographic tokens.
For many DSC users, the first question is simple: Do I need a new USB token? The answer depends on your current token, the certificate stored on it, and whether you are applying for a new DSC or renewing an existing one.
The transition date being discussed by the Controller of Certifying Authorities (CCA) is 21 September 2026. If you are planning a DSC renewal or a new certificate around this period, it is better to understand the change now rather than discovering a token requirement when you have an urgent filing or tender submission.
What Is a FIPS 140-3 DSC Token?
A FIPS 140-3 DSC token is a secure hardware cryptographic device used to protect the private key associated with a Digital Signature Certificate.
It looks similar to a USB drive, but it is not an ordinary storage device. A cryptographic token is designed specifically to protect sensitive cryptographic keys and perform signing operations securely.
For a DSC user, this distinction matters because the private key is the most sensitive part of a digital signature. If the private key could simply be copied from a computer, the security of the digital identity would be significantly weaker.
With a hardware-based PKI token, the private key is generated and stored inside the secure device. The signing process is performed through the token instead of treating the private key like an ordinary file that can be copied to another computer.
Why Is FIPS 140-3 Important for DSC Users?
Digital signatures are used for transactions where identity, document integrity and secure authentication matter. A DSC may be used by a company director to sign an MCA form, by a tax professional to complete a filing, or by a contractor submitting an electronic tender.
In all of these situations, protecting the private key behind the certificate is critical.
FIPS 140-3 is the newer generation of the FIPS security standard for cryptographic modules. It defines security requirements for cryptographic modules, including hardware and other implementations used to protect sensitive cryptographic operations.
For the Indian PKI ecosystem, the transition is particularly relevant because the CCA has issued an advisory concerning migration from FIPS 140-2 to FIPS 140-3 for cryptographic modules used within its jurisdiction.
FIPS 140-2 vs FIPS 140-3: What Is the Difference?
| Aspect | FIPS 140-2 | FIPS 140-3 |
|---|---|---|
| Standard | Earlier generation of the FIPS cryptographic security standard | Newer generation of the FIPS cryptographic security standard |
| Purpose | Security requirements for cryptographic modules | Updated security requirements for cryptographic modules |
| Relevance in 2026 | Being transitioned out of the current ecosystem | Becoming the newer standard for the transition |
| DSC Token Use | Existing deployments may still be encountered | Preferred for new compliant token deployments |
| Future Readiness | Limited compared with the newer standard | Better aligned with the updated security direction |
The important point is that FIPS 140-3 is not simply a new name printed on a USB token. It represents an updated security standard for cryptographic modules.
What Happens on 21 September 2026?
21 September 2026 is an important date in the CCA's FIPS 140-2 to FIPS 140-3 migration.
The CCA advisory asks stakeholders in the Indian PKI ecosystem to achieve FIPS 140-3 validation for in-scope cryptographic modules before this date. The advisory also describes a longer migration objective for retiring or replacing obsolete cryptographic components.
For DSC users, the practical takeaway is straightforward: if you are planning a new DSC issuance or renewal, you should check whether the token you intend to use meets the current FIPS 140-3 requirement rather than buying or relying on an older token without checking.
Care4Sign has already transitioned its DSC issuance to FIPS 140-3 Level 3 certified tokens. This means customers applying for or renewing their certificates through Care4Sign can plan their DSC setup around the newer token standard.
Will My Existing FIPS 140-2 Token Stop Working?
This is probably the most important question for existing DSC users.
The answer should not be simplified to “every old token will stop working on 21 September 2026.” The migration requirements distinguish between existing cryptographic deployments and the transition to newer validated modules.
If your current DSC is already stored on a token, check the validity of your certificate and the requirements that apply when you next need to issue or renew it.
In other words, do not wait for an urgent filing to discover that your next DSC issuance requires a different token standard.
If you are unsure whether your current token is FIPS 140-2 or FIPS 140-3, check the token model or contact your DSC provider before renewal.
Who Needs to Pay Attention to This Change?
The FIPS 140-3 transition is especially relevant to people and organisations that depend on DSCs for recurring digital compliance work.
- Company directors and authorised signatories
- Chartered Accountants (CAs)
- Company Secretaries (CSs)
- GST practitioners and tax consultants
- Businesses filing GST returns
- Professionals handling MCA and ROC filings
- Government contractors participating in e-Tenders
- GeM sellers and suppliers
- Importers and exporters using DGFT or ICEGATE services
- DSC distributors, resellers and channel partners
Where Is a DSC Token Used?
A secure DSC token can be part of the authentication and signing setup for several business and government applications.
GST
Businesses and professionals use a Class 3 DSC for supported GST portal authentication, registration, and return filing. To learn how to register and use your certificate, read our step-by-step guide on Class 3 DSC for GST Registration.
MCA and ROC Filings
Companies and professionals use DSCs for various MCA and corporate compliance activities where digital signing is required.
Income Tax
Eligible taxpayers and professionals can use DSCs for supported Income Tax e-filing and related compliance activities.
e-Tendering
Contractors and businesses participating in electronic tenders may require DSCs for authentication, bid submission and other tender-related activities.
DGFT and ICEGATE
Importers, exporters and trade professionals may use digital signatures for supported online services involving DGFT, ICEGATE and other trade-related systems.
Do You Need a New Token for Your Next DSC Renewal?
There is no single answer for every user because it depends on your existing token and the requirements applicable to your next certificate issuance.
However, if your current token is an older FIPS 140-2 device and your DSC is approaching expiry, it makes sense to plan ahead.
A simple checklist can help:
- Check your DSC expiry date.
- Identify the model and FIPS certification of your current token.
- Confirm whether your token supports the certificate you need.
- Ask your DSC provider which token will be supplied for your next issuance or renewal.
- If a new token is required, arrange it before your filing deadline.
What Is the Benefit of Moving to a FIPS 140-3 Token?
1. Updated Security Standard
FIPS 140-3 is the newer generation of the FIPS cryptographic security standard and is designed around updated security requirements.
2. Hardware-Based Private Key Protection
A secure PKI token keeps the private key within the cryptographic device rather than storing it as an ordinary exportable file on the computer.
3. Better Prepared for the 2026 Transition
If you are purchasing a new token for a DSC today, selecting a FIPS 140-3 Level 3 compliant option helps align your setup with the direction of the current CCA migration.
4. Suitable for Regular Professional Use
For users who sign GST filings, MCA forms, tender documents or other digital records regularly, having the right token available before the certificate expires can prevent unnecessary last-minute disruption.
Standard DSC Token vs Combo / Dual Token
Not every DSC user needs the same type of token.
A Standard Token is generally suitable for users who need a signing certificate for routine activities such as MCA, Income Tax or GST-related digital signing.
A Combo or Dual Token is useful in situations where both signing and encryption certificates are required, such as certain e-Tendering workflows.
Before buying a token, first identify whether you need a Signing certificate, Encryption certificate or Combo configuration.
How to Choose a FIPS 140-3 DSC Token
When choosing a token, do not select it only because the packaging says “FIPS.” Check the actual certification and whether the token is supported by your Certifying Authority and the applications you use.
Here are the practical points to check:
- FIPS certification: Confirm that the token meets the required FIPS 140-3 level.
- CCA compatibility: Make sure the token is appropriate for the Indian PKI environment.
- Certificate type: Confirm whether you need Signing, Encryption or Combo.
- Portal compatibility: Check compatibility with the portals you use regularly.
- Operating system: Confirm that the required token middleware supports your computer.
- Provider support: Choose a provider that can help if installation, PIN or token-related problems occur.
FIPS 140-3 DSC Token and Class 3 DSC
A secure token and a Digital Signature Certificate are two different parts of the DSC setup.
The DSC provides the digital identity and signing capability, while the cryptographic token provides secure hardware storage for the private key.
If you are new to Class 3 DSC, you can read our detailed guide on how to apply for a Class 3 DSC online.
Understanding this difference becomes particularly useful when renewing a certificate because you may need to consider both the certificate and the hardware token.

What DSC Resellers Should Do Before the Transition
The FIPS 140-3 change is not only relevant to end users. DSC resellers and channel partners also need to plan their customer communication and token inventory.
If you sell or issue DSCs to customers, consider reviewing:
- Your existing FIPS 140-2 token inventory
- Availability of FIPS 140-3 compliant tokens
- Customer DSC expiry dates
- Upcoming renewal requirements
- Token pricing and replacement requirements
- Customer support and installation procedures
Resellers should also avoid promising customers that every existing token will suddenly become unusable on a particular date. Instead, explain the transition accurately and advise customers to verify their certificate and token requirements before renewal.
