Remote SIM Provisioning
Remote SIM provisioning is a specification realized by GSMA that allows consumers to remotely activate the subscriber identity module (SIM) embedded in a portable device such as a smart phone, smart watch, fitness band or tablet computer. The specification was originally part of the GSMA's work on eSIM and it is important to note that remote SIM provisioning is just one of the aspects that this eSIM specification includes. The other aspects being that the SIM is now structured into "domains" that separate the operator profile from the security and application "domains". In practise "eSIM upgrade" in the form of a normal SIM card is possible (using the Android 9 eSIM APIs) or eSIM can be included into an SOC. The requirement of GSMA certification is that personalisation packet is decoded inside the chip and so there is no way to dump Ki, OPc and 5G keys. Another important aspect is that the eSIM is owned by the enterprise, and this means that the enterprise now has full control of ...

GSMA
The GSM Association (GSMA) is a Nonprofit organization, non-profit trade association that represents the interests of mobile network operators worldwide. More than 750 mobile operators are full GSMA members and a further 400 companies in the broader mobile ecosystem are associate members. History The GSMA was formed in 1995 as the GSM MoU Association as a body to support and promote mobile operators using the GSM (Global System for Mobile communications) standard for cellular networks. It traces its history back to a memorandum of understanding signed in 1987 by 13 operators in 12 countries that committed to deploying GSM for mobile services. Membership and governance Full membership of the GSMA is open to licensed mobile operators using a GSM family technology. Approximately 750 such operators around the world are full GSMA members. Associate membership of the GSMA is open to non-operator companies active in the mobile ecosystem. These include handset and device makers, ...

Machine To Machine
Machine to machine (M2M) is direct communication between devices using any communications channel, including wired communication, wired and wireless. Machine to machine communication can include industrial instrumentation, enabling a sensor or meter to communicate the information it records (such as temperature, inventory level, etc.) to application software that can use it (for example, adjusting an industrial process based on temperature or placing orders to replenish inventory). Such communication was originally accomplished by having a remote network of machines relay information back to a central hub for analysis, which would then be rerouted into a system like a personal computer. More recent machine to machine communication has changed into a system of networks that transmits data to personal appliances. The expansion of Internet Protocol, IP networks around the world has made machine to machine communication quicker and easier while using less power. These networks also all ...

Challenge–response Authentication
In computer security, challenge-response authentication is a family of protocols in which one party presents a question ("challenge") and another party must provide a valid answer ("response") to be authentication, authenticated. The simplest example of a challenge-response protocol is password authentication, where the challenge is asking for the password and the valid response is the correct password. An Adversary (cryptography), adversary who can Network eavesdropping, eavesdrop on a password authentication can authenticate themselves by reusing the intercepted password. One solution is to issue multiple passwords, each of them marked with an identifier. The verifier can then present an identifier, and the prover must respond with the correct password for that identifier. Assuming that the passwords are chosen independently, an adversary who intercepts one challenge-response message pair has no clues to help with a different challenge at a different time. For example, when ot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Certificate Authority
In cryptography, a certificate authority or certification authority (CA) is an entity that stores, signs, and issues digital certificates. A digital certificate certifies the ownership of a public key by the named subject of the certificate. This allows others (relying parties) to rely upon signatures or on assertions made about the private key that corresponds to the certified public key. A CA acts as a trusted third party—trusted both by the subject (owner) of the certificate and by the party relying upon the certificate. The format of these certificates is specified by the X.509 or EMV standard. One particularly common use for certificate authorities is to sign certificates used in HTTPS, the secure browsing protocol for the World Wide Web. Another common use is in issuing identity cards by national governments for use in electronically signing documents. Overview Trusted certificates can be used to create secure connections to a server via the Internet. A certificate is ...

Hard-coded
Hard coding (also hard-coding or hardcoding) is the software development practice of embedding data directly into the source code of a program or other executable object, as opposed to obtaining the data from external sources or generating it at runtime. Hard-coded data typically can be modified only by editing the source code and recompiling the executable, although it can be changed in memory or on disk using a debugger or hex editor. Data that is hard-coded is best suited for unchanging pieces of information, such as physical constants, version numbers, and static text elements. Soft-coded data, on the other hand, encodes arbitrary information through user input, text files, INI files, HTTP server responses, configuration files, preprocessor macros, external constants, databases, command-line arguments, and is determined at runtime. Overview Hard coding requires the program's source code to be changed any time the input data or desired format changes, when it might b ...
