Hello All;
FYI; the Cambridge lab took a serious power hit and is down. They are
scrambling to get things back up, but it may take all weekend.
Expect LAVA failures and other strange results.
Thanks;

Dear sir/madam,
Hope you are doing good!
We are working on a lightweight TLS implementation for embedded hardware
and want to add our own algorithm inside mbedTLS. As per my knowledge, we
have to add a .h file in mbedtls/include/mbedtls and .c file in the
library. Also, we have to list our algorithm in library/CMakeLists.txt.
Except these, what should be the procedure?
Also, our task is during handshake, the receiver chooses our algorithm
instead of the default one for encryption and decryption. If someone could
help us regarding this then it would be great.
Thanks in advance.
Regards,

Hi!
I am a new MbedTLS user and would like to say thanks to devs first!
From my point of view mbedtls_net_connect() could handle binding socket to a specified local client port.
Although it does not seem to be a common requirement and bloats API a little bit but otherwise user has to throw away mbedtls_net_connect()
and implement connection function by their hands.
Best,
Alex
Hi Ruchika,
as an addition to the previous answers, there is also the SecureMark-TLS benchmark from EEMBC that "Analyzes the costs associated with implementing TLS on an edge device using a common IoT cyphersuite comprised of ECC & ECDSA on the NIST secp256r1 curve, SHA256, and AES128-CCM/ECB", see: https://www.eembc.org/securemark/
It provides profiles to run benchmarks against Mbed TLS API, PSA Crypto API, and wolfSSL, see sources here: https://github.com/eembc/securemark-tls/tree/main/examples/selfhosted/profi…
The chosen cipher-suite is similar to the TF-M medium profile and it allows estimates of speed and power consumption for TLS on microcontrollers. It also allows to add - manually - footprint data.
Best
Stephan

Subject: [psa-crypto] Benchmark application for PSA crypto API's
Hi,
For mbedtls API’s, there is a benchmark application available. Are there any plans to implement benchmark application for PSA crypto APIs ?

Hello,
In mbedLS v3.4.0, I came across a build error that there are no members for type and flag in psa_core_keyattributes_t structure.
The following functions in psa_crypto_core.h access private members type and flag of psa_core_keyattributes_t structure without the MBEDTLS_PRIBATE() private access.
* psa_is_key_slot_occupied()
* psa_key_slot_get_flags()
* psa_key_slot_set_flags()
* psa_key_slot_set_bits_in_flags()
* psa_key_slot_clear_bits()
Updating to private access for attribute struct members in psa_crypto_core.h fixed the build errors.

Archanaa
