If you plan to connect devices using Vocera Collaboration Suite and
running the Apple iOS operating system with VMP,
these are the App Transport Security (ATS) connection requirements and recommendations.
- SSL is required for this version of VMP, as your
app's HTTP connections must use HTTPS.
- The negotiated Transport Layer Security (TLS) version is recommended to be TLS 1.2.
- The AES-128 or AES-256 symmetric cypher is recommended.
- Vocera recommends that the leaf server certificate should be signed with a Rivest-Shamir-Adleman (RSA) key with a length
of at least 2048 bits, or an Elliptic-Curve Cryptography (ECC) key with a size of at least 256 bits. In addition,
the leaf server certificate hashing algorithm should be Secure Hash Algorithm 2 (SHA-2) with a fingerprint of at least 256.
