The first series of articles covers the Common Mutual Authentication Procedure:

1. eSIM RSP SM-DP+ Common Mutual Authentication Part 1
2. eSIM RSP SM-DP+ Common Mutual Authentication Part 2: GetEUICCInfo & GetEUICCChallenge
3. eSIM RSP SM-DP+ Common Mutual Authentication Part 3: InitiateAuthentication
4. eSIM RSP SM-DP+ Common Mutual Authentication Part 4: AuthenticateServer
